GNC L Arginine 1000mg Supplement, Supports Healthy Blood Vessel Tone, 90 Servings

Picked up the GNC L-Arginine 1000mg because it “supports healthy circulation,” “promotes vascular health,” and all those very official-sounding phrases that definitely don’t hint at anything else at all. Nope. Nothing suspicious here. All I can say is: I feel circulated. Deeply, impressively circulated. My blood flow has never been more… directional. GNC can’t legally say what everyone already knows, so let’s just call this supplement a “confidence booster” and leave it at that. Five stars. Feeling great. Standing tall—both metaphorically and, uh… physiologically.

Good quality

1000mg…much better than the 250 or 500mg

I’ve been taking this for years. Part of my overall health regimen.

great for a pump before the gym, and i can definitely tell a difference in vascularity and vigour.

The product is fine, after all it is what it is. Making it available on Amazon is the issue, the capsules are not always available. Capsules are easier to swallow.

No flavor, big, but swallowing isn’t difficult. Seems like high quality. This has helped since I’ve been taking it for a few weeks. Will buy again.

My local GNC closed so I started purchasing this on Amazon. This really is the best l-arginine and seems to help my breathing when running.
