GLPs like tirz and reta really can change your life, and a wellness clinic isn't where I'd go for them. They're a totally different topic from the other peptides you listed. Almost none of those non-GLP ones have real clinical data, so the clinics are just guessing about their effects. Ask yourself what a clinic that sells peptide regimens actually wants... hint, it's money, not wellness. If you're curious about a peptide, read up on it in the threads on this site and other places first, and brush off whatever the clinic says beyond that, it's just a way to get at your wallet. Once you have an informed idea of what you want to test, try them one at a time, spaced out over a week or more, and get comfortable mixing a vial properly before you start.
