Credit to you OP for asking this question.It shows you're thinking and aware that Aas ain't no joke.
But ^^^^ calling "bullshit" on this statement haha
16 yr old's don't just join Meso. Obviously the gear has you thinking to some degree to ask. Don't be foolish hold out dude.
Too answer your question, no I never "felt guilty" for using Aas.Only 2 things that caused the "guilty mind" looking back. Drinking and driving often in my 20's (very fortunate didn't hurt anyone) The other "succumbing to peer pressure" in HS. Started using hard drugs and years later it became a full addiction.
Btw OP if you're feeling like I'm preaching to you. Good! Cuz I am lol
