It’s a supplement whose main ingredient is L-Arginine (in HCL form) — an amino acid.
Each capsule reportedly provides 1500 mg of L-Arginine.
The product is sold in a pack of 120 capsules.
According to sellers / distributors, BAD ASS L-Arginine HCL offers:
Improved blood flow and “muscle pump” — L-Arginine converts (in the body) into nitric oxide, which helps dilate blood vessels, potentially enhancing nutrient and oxygen delivery to muscles.
Better workout performance, endurance and energy — making it popular among athletes and bodybuilders.
Enhanced muscle growth and recovery — by improving nutrient flow and possibly supporting muscle repair and growth.
Support for circulatory and cardiovascular function (blood flow, vascularity) — sometimes cited for general circulatory health beyond gyms.
Often taken 30–45 minutes before a workout to maximize “pump” / blood flow.
Some users take 2 capsules per dose (timing may vary: before training or between meals) depending on goals.
Because L-Arginine affects blood vessels and blood flow, it's not recommended for children, pregnant or nursing women.
People with heart, blood-pressure, kidney or circulatory conditions should consult a doctor before using — as with any nitric-oxide / vasodilator supplement.
Like other supplements: not a replacement for balanced diet or proper training.
