3-in-1 Advanced Post-Workout Formula


With over 2,000 reviews, Vintage Build™ has quickly become a staple in many supplement regimens. And now YOU have a chance to find out why so many use Vintage Build™ as their only choice for advanced post-workout nutrition.

Vintage Build™ is made with:

 InstaAminos® BCAAs

These patented BCAAs are quickly absorbed and utilized by the body to enhance muscle recovery and help repair torn-down muscle fibers. InstaAminos® stimulate muscle protein synthesis and aid in the growth of new lean muscle tissue.


 Creatine Monohydrate

Creatine monohydrate is the most heavily researched ingredient in all of sports nutrition, and for a good reason — it works! Creatine helps replenish ATP stores to improve workout performance, boost muscular endurance, and increase strength.


L-Glutamine

The body needs to be in an anabolic state and maintain a positive nitrogen balance in order to maintain and build lean muscle, which is where glutamine comes into play. On top of playing a role in the growth of muscle tissue, L-glutamine becomes increasingly beneficial while in a caloric deficit to prevent muscle loss when dieting.
