Glutamine and beta alanine are legit. My mother had terrible problems with her ankle, she started drinking a glutamine enriched fruit drink.. took care of it immediately. she could tell instantly if she went a couple days with out it. Test boosters are tricky, at younger ages you can run into issues that your body will stop making its own and then fucking yourself if you go off. Not that your old, but at your age its not with out reason to assume that your bodies test levels have droped and seeking a medical professional to get the real deal is not out of the question. Basically give them the I dont have the sex drive I used to and im always tired speach. its also very hard to find anything that is legit, the shit that actually works is often made in mexico, not held to production levels it should be so you end up with a end product that is not uniform and often times as soon as the FDA gets wind of what it really is they jerk it off the shevles. Its usually incredibly hard on your liver, I had friends shortly out of HS that got into body building and I mean big time, we are talking one kid who was 5'6 245lbs of pure muscle, never used roids.. but he used some heavy otc test boosters and hes paying for it today at the age of 27 hes in for all kinds of liver issues.
