A crazy pump
I got this product as a gift in one of my orders and I was surprised by the pump. I've never tested a vasodilator before but with this one you can have your best pump.

Good vasodilation.
I tried it as a gift in an order and the truth is that it works, mixed with citrulline, beta alanine and tyrosine, you get an incredible vasodilation and pumping, I recommend it.

Extra ingredient for pre-workout
I tried a 30-cap bottle to add extra extra to my preworkout complex. I didn't notice a particular increase in vasodilation, but I must say that I already take just about every substance possible in generous doses so I couldn't quantify the effect of this product. However I do notice that the pump persists well even after post workout cardio.

To be tested
Amino acid with great potential but still to be tested . personally I am using it only in preworkout but it is still early to be able to give a full judgment

L-NORVALINE 400mg
Well
A good product at a great price which I will test for a few weeks to evaluate the real performance, but apparently highly recommended.
Minimum purchase of units!
