Mar 23, 2016 This is an area that I have a few questions about. First of course is your opinions though, My question is: Are there any effective products in this area that A)Don't give you stimulant based side effects(elevated heart rate/anxiety) B)Don't catabolize muscle I have heard that most products are not really useful unless you are less than 6-7% body fat %, competing etc which I am not. It is probably at 11-12%. I don't tolerate caffeine well, which is why I only use it Pre-workout. Trenbolone isn't an option either because of certain side effects. Prior to using bunk IGF-1 from a # of companies, I used a peptide labeled as that. I noticed my body fat dropping, muscles staying full...even though I was hungrier & eating more calories. I never got that effect from anything, steroids or supplements & it was pretty amazing to see.
