you take risk every time you buy ugl or alleged hg if it aint from the doctor how do you know without testing it .im using prescription test now its the balls smooth no pain and lord am i getting strong .im using vet grade npp bought from a vet overseas (for fighting cocks) it burns like hell and its low dosed so i have to use a large amount for every other day shots .ive used and still use ugl stuff hit and miss here somtimes i grow and somtimes i dont feel crap .and somtimes i pay way to much so these days take what you can get just be careful you may be buying plain oil with a little ba in it for pain so you think its working.
