Been ordering from them for years without an issue. My last order they created a shipping label and never handed anything over to the carrier. They haven’t responded to emails, or messages through their site. Their phone is out of order. They’ve obviously turned into a complete scam.

If I could give no stars I would have. This company is the worst peptide scam artist site on the internet. They create a shipping label. Then never send anything. And they don’t refund money back. Scam company, and so unethical. F Extreme Peptides

I placed an order for 10 vials of Semaglutide and when I opened the package, not one of the 10 vials had a label on it!! How the heck am I supposed to know what is in these vials? Now I'm out $600. Their phone number is not working. Their submit form on their website is not working and neither is their phone number. I am pissed ........

Don’t want to even give this company a star. Been ordering from them for 12 years. Paid for 2 orders in December 2023 and still have not received them.

Well, I should have read reviews before I ordered. Label created but usps has not received the package. I'm going to attempt to get my money back through my debit card company.

I submitted an order with extremepeptides.com and the tracking says 'tracking number created' and nothing else. It was never given to USPS they just stole my money. I never received my product or refund and they have ignored my calls and emails. Would avoid doing business with them if you don't want to be scammed.

I'm so tired of having to beg for my product to be delivered.
