D Aspartic Acid

D Aspartic Acid from The Protein Works™ is 100% pure D Aspartic Acid. It is an amino acid that has been shown to play a key role in helping promote muscle tissue growth and libido enhancement. Supplementing with TPW™ D Aspartic Acid can help stimulate certain signal molecules within the body which then in turn enhance activity within the testes and pituitary gland to help enhance lean growth, strength and energy.


D Aspartic Acid in Sports Nutrition

Since its introduction into the sports nutrition market, many studies have been done on D Aspartic Acid to test its performance enhancing properties. In one particular study, experts supplied a group of healthy, young males (aged between 27-37) with a daily dose of 3.12g of D Aspartic Acid for 12 consecutive days. Results showed those male subjects that received the D Aspartic Acid displayed a 33% rise in T-levels compared to those who didn’t. Consequently, D Aspartic Acid has since been praised for being a supplement with great muscle building and strength enhancing potential.

There is only limited research backed results based on d-aspartic acid and i personally did not feel it helped me. That said I'm only in my early 20s so my test levels are already high! Might work better for people late 20s up
just received this today only ordered it last night!! cant wait to try it at the gym tonight and see if it is as good as the other products from TPW!
Quality product from a quality company
Only been a week since taking this and noticed lifting more.
Gd product i mix with taurine and creatine and not sure which one but kind of small bits dnt dissolve so left with what feels like bits of sand but overall gd price for a quality item.
Feel more pumped and so far has only had a positive effect on my training. Mixes well and no bitter aftertaste. In fact i mix it with my creatine to overide the creatines taste!
Looked up about this stuff before buying and it defo gives boost in gym
Test is defo up been on it for over a week now before review and defo working
One side affect tho is your horny
24/7 lol
If you are not very good with tastes then I would prob recommend not having this in water.

It is bitter to say the least, mixed very well though!
Always used D Aspartic so glad you're now stocking it in its purest form
I read up alot on d aspartic before buying and the studies were right, test definitely higher
