What Does Instantised Branch Chain Amino Acids Stand For?

Instantised Branch Chain Amino Acids (iBCAA ) from TPW™ are made from Leucine, Isoleucine and Valine and are renowned for their muscle building qualities, along with their ability to prevent muscle loss when taken preworkout. During periods of intense training the body can enter into a state where the muscles begin to breakdown. But because iBCAA’s are absorbed directly into the muscle tissue and are metabolised quickly, taking them preworkout or intraworkout can help to prevent this muscle breakdown and ensure your muscles remain in a more positive state during training.


How Can iBCAAs Help Muscle Gain

Studies have demonstarted that Instantised Branch Chain Amino Acids (iBCAA) have impressive muscle building properties when taken post workout. TPW™ iBCAA’s have been made in the optimal 2:1:1 ratio (leucine: isoleucine: valine) especially important in the post workout window. Research shows leucine (the dominant constituent of our iBCAA) can enhance protein synthesis by as much as 33%. Protein synthesis is the process by which the muscles use protein to repair and regrow - so iBCAA supplementation post workout can be particularly important to strength athletes or those wanting to build quality muscle.


How Are iBCAAs Made?

It's important to note there is a fundamental difference between products advertised as "BCAA" and "iBCAA". The "i" stands for instantised which means our BCAAs have undergone a high tech manufacturing process. This ensures that when mixed with water, our BCAAs dissolve fully. Standard, cheaper BCAAs, when mixed with water cannot dissolve and 'lumps' float on the top of the liquid. This not only makes it harder to consume but also takes longer to reach the muscle. Here at TPW™, we only manufacture iBCAA as we believe in only offering products that achieve the best results for our customers.


How Are iBCAAs Flavoured?

Whilst Branch Chain Amino Acids are backed by years of research, they are also known for having a slightly bitter taste and not mixing ever so well. That’s why here at TPW™ we have ensured that our premium quality BCAA's are instantised to ensure easy mixing and solubility when added to any protein shake. Plus for those like to consume their BCAA’s preworkout or intraworkout on their own, the TPW™ Product Development Team have introduced flavoured iBCAA powder: available now in Berry Blitz, Orange Burst and Green Apple Spike. Made using our unique all natural flavours and colours, flavoured iBCAA powder mixes into a fruity cordial drink that’s not only refreshing but backed up with scientific support. Find out more about TPW™ All Natural Innovative Flavours.

Each ingredient supplier must pass rigorous audits and checks before being given the TPW™ quality seal of approval. Traceability, quality, and consistency are the three things we demand on every single ingredient.

good for cutting! love it
I recently placed an order for a 500 gram bag of this product in Green Apple Spike flavour which I have tried previously and found to be pleasant tasting when 5-10 grams is mixed in 250ml of cold water.

The mix-ability of these amino acids is great due to them being instantised making them water soluble and allows for them to mix without leaving clumps and excess foam at the top of your shaker.

I have had standard amino acids from Body *uilding War*house and M* Pro*ein in the past which have been a nightmare to mix and even worse in cold water leading to mass amounts of foam and lumps at the top of the mix.

These are available in a 2:1:1 ratio which has been proven sufficient for increasing protein synthesis.

I tend to add extra Leucine powder which is also available at TPW to bump up the content of this amino acid, this allow for me to be able to customize the ratio when required and turn it into 4:1:1 or 8:1:1, it is also a great way of saving using money on using excessive amounts of iBCAA and allow for you to use the same 5g serving and add 2-3 grams of Leucine powder to make it more effective.

For increased muscle growth and recovery i recommend consuming 5 grams of this product 5 times a day.

1st serving in the AM when you wake up to prevent muscle catabolism, 2nd Pre workout for a boost in energy stacked with a caffeine based pre-workout, 3rd intra workout to prevent muscle breakdown and improve protein synthesis, 4th straight after your workout to once again boost protein synthesis and make your post workout recovery shakes more anabolic and the 5th serving before you go to sleep to aid protein synthesis and improve leucine content of your pre bed casein based protein shake.

BCAA's are great for when you are cutting by allowing for you to retain muscle tissue whilst reducing body-fat levels when performing fasted cardio / weight training sessions.

Sometimes instead of consuming 5 separate servings I just add 20-30 grams of this into a 2 liter bottle of water with some added glutamine and sip on it throughout the day to drip feed the muscles amino acids.

This product is really good. I've used it for a week now and I take 5grams before a workout and 5grams an hour before sleep. It stops you feeling fatigue after a workout and stops muscle breakdown which is extremely good.

I got the Apple Spike falvour. The colour is fantastic and mixes well, smells just like apple starburst. Unfortunately, doesn't taste quite as nice but it's definitely not the worst.
Good product, would recommend!

I take a serving 2 times a day and i'm really starting to lean up! BCAA's are a hidden gem in the bodybuilding world. TPW's BCAAs taste and mix great. I've tried all three flavours, Apple being my favourite. They are slightly sour, but that makes them so refreshing!

have been using these Instantised Branch Chain Amino Acids for a month now and feel they are a an awesome product and even superior to all other versions which I find to clump when mixed in water and leave residue at the bottom of my shaker cup.

iBCAA mixes much more easily with none of that irritating froth that floats to the top of your shaker cup.

These are dosed in the ideal 2.1.1 ratio which is more than adequate for muscle building purposes.

I find it to be best to dose this product at 5-10 grams per serving and to have up to four servings a day, one first thing after you wake up, one pre workout, one intra workout and another before going to sleep, by having multiple servings you improve protein synthesis throughout the day and prevent your body from breaking down its own muscle tissue by using this to provide them with the energy that they require.

BCAA's work great first thing in the AM prior to some morning fasted cardio to provide a boost in energy and allow for your body to burn fat rather than your lean muscle tissue.

When I have used BCAA's pre workout or intra-workout I have noticed that I am able to push harder and require less rest between sets, normally I require 1-1.5 minutes rest but after 10-15 grams of this I only need 45 seconds rest, this is great because it cuts down on the time spent in the gym.

iBCAA gets 5/5 because it is a high quality refined BCAA product with great mix-ability and taste in Green Apple Spike and Tropical Punch, the Tropical Punch is my favourite so far and even makes the greens powder taste great, by having this in the same flavour I can easily combine the two product to improve energy levels for my AM cardio sessions.

Another great product! I've tried berry blitz and tropical punch flavours and tropical punch was by far my favorite (reminded me of fruit salad sweets :D )and was a really great flavour. Anyone that has ever got a bag of unflavoured BCAA's will know how awful it tastes so the fact that this tastes so good amazes me!

If your a first time buyer use my Code for a free small bag of protein JS117090 :)
Noone who trains should be without this stuff - it's amazing - just read up on what BCAA's do and you'll buy some straight away!

You feel good taking it too - but don't get unflavoured unless you think your hardcore like me!! Big mistake hahaaa!

So I have read up on BCAA and benefits, I have been a long time swimmer but have had a 2 year stint out the pool, I have been using the Tropical Flavour 2 scoops of iBCAA wit 400ml of water whilst training and swimming and have noticed a difference already in gains, in that little extra energy from the sugar hit of each sip, and also in the motivation to push that last rep or last sprint, I will be buying again, not tried the other flavours but Tropical is nice and not overpowering - tastes a bit like robinsons cordial, I use this during and a few BCAA tablets after to top up before a shake.
if your looking for glutamine you should buy this product! if your looking for a faster rate of recovery and be able to bust more pumps out in the gym, this is the product for you!
and also comes at a cheap affordable price!
if you want BCAA you should get this product, delivers you good BCAA and I have seen a slight change in recovery rate! this is cheap BCAA and is the bomb!

Used in the past Instantised Branch Chain Amino Acids are a superior product to the normal version being that they mix much more easily with none of that irritating froth and bits sinking to the bottom of your shaker cup. These are dosed in an ideal 2.1.1 ratio which is more than adequate for muscle building purposes.

5/5 a top notch high quality BCAA product with great mix-ability and taste in Green Apple Spike and Tropical Punch.

I have used other amino acid products before and this one is as good if not better than them . great value for money and mixes well for a bcaa . No complaints
always use this to sip on during a workout , have started to add some electrolyte powder to it also now. A staple in my training and good value .
high quality BCAA , opted for a flavoured version in orange , use this intra workout , does the job well
Bought Berry Blitz. It is the most horrible thing I have taken in my life. Undrinkable.
Apple flavor is good not too sweet so easy to drink while training, mixes well and at a great price
Mixes well and taste great but not sure if had any real effect for me. Certainly makes a nice drink intra work out though!
Guess anyone reading a review here knows what these bad boys do so that just leaves flavour review. Tropical punch is great, taste is beyond palatable. Mix with water 10/10 no residue or grainy left overs. A must buy in an awesome flavour.
A very nice product and a good buy.
quality product works the first time i use it feel energy in me and no fatigue at all
Great intra workout in with your gallon of water!

Green Apple Spike is amazing.

Mixes well, tastes great and even turns the water a funky colour!

Great value TPW
I've just bought my second bag of ibcaas which is the powder. I really feel the difference from taking them. Less fatigue in long sessions and good results from increasing muscle mass, along with a good eating plan. Defently worth getting.
Prevents muscle fatigue intra-workout, and helps with recovery for the following day. Would reccommend 10g per serving as it's been proven to be the optimum serving size regarding the benefits.
First tine with BCAA's and not disappointed! Went for Berry Blitz and found it a far too strong and potent a flavour when mixed with 150ml of water as directed.

I mix with 300ml of water before a weights session or long session on the bike as well as adding to a breakfast naked protein shake with coconut milk, berries, super greens and cinnamon.

Got the tropical and tastes great, another top product
Great product - would love to see some without the artificial sweetener though...
I've got the tropical flavour and my friend has the berry blitz which I have tried. Both taste nice with 250-300ml of water and mix well in my shakers. They've been working for me as far as I can tell as I have been retaining muscle whilst loosing fat.
Love this iBCAA
I bought the 'Berry Blitz' flavour, I was hesitant as I normally despise anything with sweeteners in it but this was ok, could not feel any real aftertaste and it was pleasant mixed with 150mls of cold water. I just mixed it in a glass with a fork (I was home :) ) and no problems. Will definitely buy again, thank you!!!!
Berry blitz flavour is just tooo nice. and great product for retaining muscle.
defiantly worth buying makes all the deference to recovery
These mix well, taste good and keep you feeling refreshed throughout even the toughest workout
Brought unflavoured at first which was a mistake as the taste really wasn't great but thats to be expected. Mixed with juice it was a bit better but not ideal, so decided to get Berry Blitz and I must say it tastes great and have it mixed in with my water at the gym. Great stuff.
Gives me energy for a pre-breakfast workout. Berry tastes good and mixes well
Ordered this to replace another powdered bcaa that was running out - lovely flavour (apple), great for early morning training and during training generally, especially longer sessions. Much nicer than pill based BCAAs
Does the trick & tastes good (Green apple spike) which is always a bonus
Ordered the tropical flavor. Mixes very well and taste great.
Ive been using the tropical punch flavor and its great it really adds flavour to me pre workout its a bit like mi wadi and it mixes well. Definitely useful for building and recovery
this product is perfect for that additional boost when playing 90 minutes of football
Tastes good. Two scoops Berry Blitz during my workout and keep topping up. Easy to mix and tastes like cordial
Love the product. Great price compared to other brands considering it is still as good. Will be buying again not too sure if i will get unflavored again though as the the taste is pretty nasty when taken on it's own.
Got these in new order after being on the BCAA complex tablets, so far so much easier to be able to have it in powdered form. I stack mine with creatine pre workout and also just add few scoops to water during day. Essential for anyone looking to build quality muscle size and also recover!
Really Great Product, I take them intra workout & then throughout the day, I find I am able to train more intensely towards the end of my workout than I usually could.
Great product and definitely helps quicken the recovery process....just wish I hadn't got the unflavoured one :(
Really liking this product.

Apple is by far my fav
Never ever tried BCAA's before and heard alot about them, especially the benefits of taking them.

So i'd bought the Apple Flavour and took 4 scoops with a Skimmed Milk Whey 90 Shake 450ml.
Drunk 200ml before workout, 100ml during workout and 150ml post workout. I have NEVER felt so fresh from lifting weights for 30 minutes in the gym. The BCAA's really do help your muscle tissues from breaking down.

Im pleasantly suprised how great this product is. Ive used it 4 times now.

A Whey Protein Shake with BCAA's is A MUST for any serious gym user wanting to achieve big results!
I have tried multiple way to supplement BCAA, whether it be in powder or tablet form.

I hate swallowing tablets especially BCAA ones that are massive, I have also tried other BCAA powders which mostly have tasted disgusting.

As you can imagine I was sceptical, but one sip of the apple flavour and I was converted. The flavour is extremely refreshing with cold water and I'd rate the taste 10/10!
I bought the apple flavour, which when mixed in 250-300ml of fridge cold water is very refreshing indeed. I take this pre and intra workout, and have found new levels of intensity from the first day of taking it. At least for me, this product has the desired effect. Very impressed so far.
... feeling good on the quick recovery, only thing I've changed has been this product.

PLEASE NOTE the unflavoured product really is not tasty. Spend the extra bit and get some taste in there.

Mixing with other products does not remove the taste.

Good product, shame it's a bit aggressive on the oral intake.

Will be ordering flavored next time.
Just received this as i sold my Optimum Nutrition BCAA powder as i literally could not handle it. It was awful! Bought this as i had BOGOF with protein discount card VIP and it was a good deal (its cheap enough as it is.) Arrived today and tried it for the first time (orange.) Got to say its brilliant. No nasty stuff at all and with 200 instead of 100ml of water mixed in its just like diluted juice. VERY VERY SLIGHT aftertaste which isnt the best but as far as BCAAS go thats insane! Definitely sticking with this from now on! GREAT PRODUCT
This stuff is the best out there as far as BCAA goes. My tip, 2 scoops of orange and 1 scoop of apple with about 300ml of water used intraworkout is the 5hit!!!

Upon reading I would only need between 100-200grams of water and a couple of small scoops of powder I immediately thought it was going to taste like some ultra concentrated pre workout supplement..... I was wrong the berry blast flavour is spot on doesn't taste in natural or strong more like cordial, it got me through my workout nicely which was a surprose as i didnt use it as a pre woekout and I didn't have that post workout crash or jittery feeling you get with a lot of supplements that have stimulants in. Will be using this as my pre workout from now on.

This has to be the best mixing and tasting powdered BCAA around!!
The apple flavour is so good.
I could drink it all day

take as an intra drink, like the apple flavoured one, works well , highly recommend

Before I had tried various bcaa's in tablet form, all were just horrible

No I add the berry blitz flavoured ibcaa to my unflavoured whey 80 or unflavoured Ibcaa to my caramel flavoured whey (which is even better as it takes away the too sugary taste)

The mix is just fine and I take it before and after every workout
I take a serving 4 times a day and i'm really starting to lean up! BCAA's are a hidden gem in the bodybuilding world. TPW's BCAAs taste and mix great. I've tried all three flavours, Apple being my favourite. They are slightly sour, but that makes them so refreshing! Pre - Intra - Post workout!
I bought this to use for fasted training sessions and long distance bike rides to help prevent muscle breakdown and it definitely works!! DOM's has reduced, endurance whilst training seems to of improved and it tastes great!!
Such a nice product to drink pre workout to fuel a fasted session. Flavour is spot on, not too sweet and overpowering, and no significant aftertaste. Mixes well, price is spot on. Excellent.
Wow, you guys really know what your doing! Had a weeks lay off from taking this product, boy didn't I notice the difference, was permanently sore with DOMS. Glad to say I'm back on it, Orange Burst, what a flavour, I recommend it to everyone. Keep up the good work:)
lovely flavour and good start and finish to every day
Mixed easily, green apple tastes better than most and really helped with DOMS when taken intra workout! Took as a supplement on non-training days just to help speed up recovery.
1st purchase from the company being ibcaa green apple spike, wow how nice a taste. been using amino acids for a year now and they all taste disgusting, such a nice change. 2 scoops in 100ml water, yummy recommend to all. Cant wait to try my cherry bakewell isolate tomorrow after training now. :-)
I take this when i wake up
pre workout, intra workout and post workout

i have noticed less fatigue, doms and an increase in energy when working through sets

Berry Blitz tastes good and not bitter like others i have tried.

i like mine a bit thinner and mix it with 200ml of water only.

Will order again once ive used this batch

5 stars!
Use this during traing has helped
Alot taste is ok less doms and less
Muscle breakdown wouldnt train
Without it lasts ages aswell defo buy
(Berry Blitz) Take in my workout water bottle and with post workout shake, mixes well, tastes great, will keep buying. But the best thing about this product is, I've forgotten what DOMS fells like, no matter how hard I push myself! Yet another great product from TPW.
I switched over from Xtend to this. Xtend was too sweet and felt like the acid in it was making my lower teeth sensitive. This stuff is simple and tastes good. Have tried both green apple and berry blitz. the other reviewer is right that its weak with a lot of water but I like it that way.
  • 0 of 1 people found this review helpful
Tried the Green Apple Spike flavour and it tastes great when mixed with around 100ml of water - any more than that and it is fairly weak, but still palatable. But for anyone wishing to mix this in with their water during a workout might be disappointed with the strength of the taste, or need to use more powder than suggested. Froths up a little bit when shaken too, but I found it to be fine when stirred. The idea of a flavoured BCAA is great though, and another brilliant TPW product.
  • 1 of 1 people found this review helpful
Switched my BCAA over to TPW from MP unflavored and i'm not disappointed! I only used it for the first time last night so I can't give any long term insight but the taste was bloody great!!!
Taste Great Mix well what's not to like
  • 0 of 1 people found this review helpful
Very good product, very good price! I use the un-flavoured product mixed with a small amount of squash to mask the taste. Mixes very well in a standard shaker.
Have been using this since christmas and have really noticed improvements in my training, specifically an increase in my performance levels.
As I said you have to get used to the taste if not mixing into a flavoured shake (I take it with water during my workout) but ultimately with this product it is about performance not taste so it gets top marks from me!
Guys really good product. Always take BCAA's but converted to iBCAA's after it mixes in my shake really well! Keep doing these and you have a customer for life, Great success
