I like it too. Great for sleep and funky dreams. Might help “anabolically” when dieting because you may not be getting enough zinc/magnesium when dropping calories.
Personally, I like it a lot because I sleep better with it. One thing I noticed was that it contains higher than 100% of the RDA for zinc, magnesium, and vitamin b6, and was concerned about long-term toxicity issues. But then again the RDA for calories is only 2000…
I have used ZMA on and off. It does give decent sleep. However, everytime I go on it after a period of staying off it, I experienced some strength gains (probably due to the increased T levels). Not a bad supplement.
