Highly satisfied with my experience with Prime Labs. I truly appreciate how detailed and informative their peptide descriptions are, it made understanding the products easy and reassuring. The ordering process was quick, simple, and hassle free. Shipping was incredibly fast, and the research product works fantastic. The pricing is also very reasonable and fits well within my budget. I highly recommend Prime Labs!

Product has always arrived on time or earlier. I have only ever had one issue with a product getting lost in transit and to my surprise they were very communicative. They even gave me a new shipment after they found that the deliverer lost the order. Will definitely continue to use prime lab

Delivery is fast; I receive my product a few days after I order it. I have been taking Retatrutide for 4 months now and have lost 40 pounds! I am so happy with the results.

The entire purchasing experience exceeded my expectations. The communication was excellent from start to finish. Their customer service was professional, responsive, and genuinely committed to solving every question quickly. The products arrived well packaged, professionally sealed, and exactly as ordered. The quality of the packaging and presentation gave me a great deal of confidence. Based on my experience, I can confidently recommend Prime Lab Peptides for both their outstanding customer service and overall professionalism. I will definitely order from them again on my next trip to the United States.

So far so good. Ordered Bcp-157, TB-500 Semaglutide, Glow, MeloTan 2.. All seem to work how they should. Shipping is lights out fast. Most of the time from order placed to my mail box is 3-4 days tops. Pricing is a little more than other companies. But you get what you pay for. The fast shipping and quality make up for any price difference. I’ll keep ordering as long as they keep up the fast shipping and quality. If you are seeking out cheap pricing I’m betting you’re not getting great quality and shipping in 3-4 days.

The peptides were timely and instructions for use were exceptionally detailed and clear (but not so detailed where one gets lost). Will definitely be purchasing from here again.

The products are real, I'm losing weight in a dose-dependent manner, and I recommend this company. The products arrived and everything was in order. After my initial review, customer support reached out, acknowledged the processing delay on their end, and offered me a coupon toward my next order. I appreciate that they made an effort to make it right. I hope these products are real and anyone who can verify that they are shares there experience!

Easy to order and complete purchase. I have been ordering from them since January 2026 and have received every order on time with no issues. The products are verifiably third party tested and work as they should.

How reviews work here

Where these reviews come from

Two sources. 1,272 were left by customers on our former public review profile and rebuilt from the notification we received for each one — the wording, rating and date are the customer's own. The rest were written here since, after an order or directly from this page.

Every review is read before it goes live

A human reads each new review for abuse, defamation, personal data or off-topic content — never for its rating. Every decision is logged with its reason, and a published review appears word for word.

Nothing is filtered by rating

The 19 one-star and 8 two-star reviews are kept and readable through the rating filter. A page that only shows praise is not worth reading.

What is not here

Reviews their authors deleted, and reviews taken down before the former profile closed, are excluded — republishing them would put back online what was removed.

How the rating is computed

A plain average of 1,276 ratings, every review counting once. No weighting, no recency bonus.
