One week that ordered and didn't shipped . did not answering my emails. Lost my money and time.

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.
