Positive experiences
“Something I found that makes my meds work way better is Citrulline 2g + Arginine 2g twice daily.”
“Any Vasodilator should work for promoting a restful sleep.. I prefer L-Arginine.”
“I actually take 6g of L-Arginine powder in water on an empty stomach every day. It has helped, but I am still searching for a better solution.”
“a nice Zinc and Magnesium supplement combined with L-Arginine has helped me far more than Horny Goat Weed.”
“I know L-arginine helps with erectile dysfunction and so does many others.”
“I know L-Citrulline should be better but I had much better luck with 5-6 grams L-Arginine in that area.”
Negative and mixed experiences
“I tried so many things – L-Arginine, Citrulline, Zinc, Omega-3s, training, clean diet. Some things helped a bit, but nothing really fixed it.”
“I also started taking L-Arginine with it as I had a bunch of pills but to be honest I didn't notice any added pump at all.”
“I tried different forms and dosages of Magnesium, Zinc, L-Tyrosine, melatonin, L-Arginine, ALPHA-GPC... most of them didn't provide any meaningful and noticeable benefits”
“two weeks of arginine supplementation seemed like it rolled back easily a year or two of old injuries... best sleep of my life... bite my tongue more often”
“I used to take l-arginine and Horny Goat Weed ... I - think - they helped, a bit”
