I’ll chime in :flame: .
Many members here are AAS users; their average gains haven’t been that much different than non-users. So, lil is right I think, an higher level of test will do nothing for gains.
Anecdotal evidence seems also suggest that anti-depressants, sleeping pills etc. affects negatively growth. I suppose the reason is that they mess with nocturnal REM phase and, more generally, lower EQ.
Finally, in the case of extender/ADS users, this last facts can help in length gains, exactly because the resistance opposed by smooht muscle is lowered, so all the tension is put on TA, and elastic stable deformation is achieved easier.
So, chances are you are using the device in the wrong way. How many hours daily are you wearing it? How many days per week? How much tension?
