Your method of packaging your peptide was done with minimal protection of heat. It was shipped USPS and your method was to wrap in bubble wrap. The peptides have sat in the mailbox in the full sun all day . The powder is solidified and possibly damaged

I have bought probably 10 different products from here, and I have always been satisfied with the purity and quality. I would rather have clomid in pill form, but I buy it from here even though it's liquid, because I trust the quality. (there's a lot of fake Clomiphene online)

DISAPPOINTED
I order retatrutide from Extreme Peptides. I have been using it for 4 weeks, and I have not felt any decrease in appetite or food noise. I have not lost a single pound. I do not believe this is true retatrutide.

Hello. I recently purchased retatrutide and melanotan from your site. I have used both of these compounds from peptide sciences numerous times so i am fully aware of how I respond to both compound. I am on day 3 of taking your Reta 20mg and melanotan. Neither are doing anything. Dosing Reta @4mg Which usually makes me struggle to eat ANYTHING. My appetite is absolutely normal on your compound. And I haven’t lost a pound I lost 35 pounds in 2 months on peptide sciences gear. Please respond. I’ve spent a lot of money on your site and feel like you sold me fake gear.
