Peptides are cope twin. They have more cons than pros. They are expensive too.
If you think with buying peptides and injecting it your gonna grow like 30cm or smth around that don't do it. I know a lot of ppl who bought peptides and injected themselves they only grew like 1.9 cm or smth around that. their jaw grew too but uneven and their face got asymmetrical. Instead of peptides you can sleep 9-12 hours-sprint 2-3 days a week-and eat healthy. Ppl who injected them selves peptides nearly all of them got carpel tunnel syndrome. Their organs got too big like heart is a muscle And peptides like igf-1 makes muscle grow and their heart got bigger. It may seem like a good thing but like breathing was harder and every heart beat hurts. And way worser things like heart failure
