They have a sale around every holiday. They are easy to order from. They are swift to deliver. If you need help, there’s a phone number and someone will either answer or call you back within their business hours.
Easy and simple process. Great product
Good prices, fast delivery. Great product
The website was set up nice easy to navigate and check out.
I would like an email after I place my order so I can track my order. Then I will know when it's arriving.
Affordable, great quality, and fast delivery
The billing was confusing because two separate emails showing the amount paid were sent leading me to think I had been double charged. I emailed the company who responded within two days after researching and explained why it occurred and alleviated my double billing concerned. I suggest this is rectified by ensuring only one email being sent to avoid confusion.
I know I can trust that my order will be on time and that the contents are what they say.
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
Good customer service , fast shipping .
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)
Quick shipping great Customer Care A+ service quality products!!
The pure speed and the care of the package
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.
I am so thankful for the quality of your products, and they are shipped quickly. You’re the only company that I trust. Thank you
