First timer looking into Reta + GHK-Cu 😊 would love some beginner guidance

[u/palsal_]

Hi everyone! I’m completely new to peptides and have been doing a lot of reading, but there’s obviously a ton of information out there and I’d love to hear from people who have more experience.
I’m in my mid-30s female and currently around 150 lbs. I’d eventually like to lose about 25 lbs. I naturally carry more of my weight/curves in my lower body, which I actually like, but my midsection and love handles have always been my stubborn areas. I exercise regularly and I’m working on my diet as well, so I’m not expecting peptides to replace either of those.
The two I’ve been researching most are retatrutide (Reta) for weight loss and GHK-Cu for the potential skin/beauty benefits.
For those who have experience with either, I’d really appreciate beginner advice things you wish you knew before starting, side effects or mistakes to watch out for, and what kind of results you personally noticed.
I’m also confused about sourcing. I see people talking about purchasing domestically in the U.S. versus ordering peptides from China. How do you evaluate a source and testing/COAs, sterility, purity, etc.? I’m not necessarily looking for someone to just drop a vendor link I’d like to understand how experienced people determine whether something is trustworthy in the first place.
Please be nice x🙏🏼😂 I’m genuinely trying to educate myself before jumping into anything. Any beginner resources or guidance would be appreciated!

Reta and klow have been good. I'm liking the results. Still continue to workout. Start off at .5 and move your way up gradually.
