Plasm Caps V2 is a non-stimulant nitric oxide capsule that is designed to improve endurance, blood flow, and overall vasodilation to the extremities. This can also be used as an additive to any stimulant pre-workout to obtain better pumps and blood flow, but differs from Plasm Surge in its ability to produce nitric oxide in complementary - yet separate mechanisms.
Plasm Caps facilitates the creation of higher nitric oxide levels - this is accomplished through symbiotic nitrate reductase activity and endogenous antioxidant enzymes that produce nitric oxide from dietary nitrates. For a more comprehensive breakdown see: (link to longer writeup).
