I have been longtime users of GAT products. Gives a nice pump and lasts the duration of the workout. I would definitely pair it with a preworkout though. Personally I’ve tried pump products from multiple companies and this is one of the top tier products.
Overall I really like this product, I like how they offer the non sweetened/flavored version because I add it to my regular pre for enhancing effects. However, my one and only critique is that they should either completely get rid of L-Norvaline or replace it with something else. The research on that seems to point towards negative brain effects with long term use and I imagine they can easily get rid of this/replace and still keep a lot of the benefits of the supplement. 4.5/5 stars if I could.
