Thorne Research Perfusia-SR® -- 120 Vegetarian Capsules
The best arginine product I've used
I've used several arginine, and arginine/ornithine products before. Generally, I try to use to pre-workout or in cold weather as a vasodilator.
Unless the arginine is time-release, your body will quickly metabolise what it's provided, and results will only stick around for a short period (say, 20-30 minutes). This stuff provides and effective, sustained release. I've seen this stuff relabeled and sold for more. I do wish it was a bit cheaper, but you get what you pay for.
Thorne Research is also a very solid company, and I trust them to not cut corners. This is my 3rd bottle of this stuff, and I'll surely buy more.
