The suppliments are nothing but Placebo and a marketing ploy.
The research on L'Arginine is far from conclusive and actually very contradictory. The only studies which show increased performance was at a level that NO suppliments offer, and a level that was unsustainable for prolonged periods.
So this Argi boost, is a placebo at best,
I go to the gym with water, train hard, sweat a lot, then drink water and have a banana on the way home. No Instagram, no check in, I do it because it makes me feel good. Not because i need it to run my business.
Tragic
