I’ve only really tried one vendor. Through a trusted source I know personally (stuff actually works, and a few other people I know are also on this stuff)

Aeon compounds. It’s expensive. But also so are most companies besides getting grey straight from the source. Reta & GLOW stack. Just reconstituted my last vial of Reta with this company. So far have lost 19 lbs in 2 months! Feeling great so far. 3 weeks on their glow stack. Haven’t seen anything noticeable so far. I’ve heard it takes a super long time so I’m playing the long game here. That being said I want to branch out and have been doing tons of research for my own company to find that is also cheaper. Ordered from Genpeptide 4 vials of reta, 2 vials of Kpv, and 2 vials of glow stack. And a couple vials of bac water. Spent about $400 total for 10 vials. Anyone on here have experience using Genpeptides? All their coa’s seem to match every lot # that was given to me.
