I'll say this about peptides as PEDs, as I train pretty regularly alongside people who use them.

If your skills suck, it won't make you better.
If you're a good amateur and not an elite professional pushing the boundaries of what is humanly possible, it doesn't give you that much of an edge compared to just being diligent with your recovery, nutrition, sleep, and following smart programming that doesn't leave you at the ragged edge of over-training.
The biggest users (abusers?) I've seen are folks who are just trying to do too much when it comes to balancing training vs real life commitments, weekend warriors who think they can make it to the CF games while holding down a 40 hour a week job and raising kids if they just did 'more'.
And >35 year old men who haven't made the proper lifestyle adjustments in terms of nutrition, sleep, and programming to fit their mid life biological realities, and instead try to eat, drink, and train as if they're 25, but instead of adjusting their lifestyles, look to peptides as a quick fix.
And guys who are eating Doritos and chocolate milk, LARPing as strength athletes, realizing their health markers are horrible, but instead of embarking on serious lifestyle adjustments, cling to their identity as a 'lift big, eat big' kind of guy and turn to peptides to try to compensate.
And guys who don't want to pay the dues in the iron game, do the work, do the reps -- who want in 2 years what it takes 5 to 10 years to get.
All that being said -- it's your body and your choice.
