Only giving a 4 because I haven't started my research yet. Ordering and shipping were amazing! All items were in great condition and nicely packaged. So far I do recommend PrimeLab Peptides.

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.

If you asked me last month how I liked this company, I would say they were great. I placed my second order on Dec 6th and still have not received it. I emailed twice to get a status update and have yet to get a response. Very disappointing. I was confident this would be the company I would use going forward but I’m second guessing that decision now.

Five stars for Prime Lab Peptides. Every order feels smooth from start to finish. The products arrive well packaged and clearly labeled, which builds trust right away. Quality stays consistent across orders, which matters a lot. Customer service stands out. Messages get answered fast and with care. Questions never feel rushed or brushed off. Communication stays clear and respectful, which makes the whole process feel easy. Overall experience feels professional and dependable. I feel confident ordering here and recommending Prime Lab Peptides to others. Solid products, strong service, and a team that shows up.

This order was delivered in 4 days however I placed another order the same day as this order on Dec 7 th and that order as of today has not shipped. I did email customer service and they informed me that it would be shipping soon but as of today Dec 15th I have not had any updates on my 2 nd order. I am disappointed since they advertise 2 day shipping and I signed up for VIP. I’m getting nervous and thinking I might not receive my 2nd order at all?

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.
