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

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.

I’ve already made four purchases on this site and couldn’t be happier. The products arrived in just 2–3 days, all perfectly sealed and in great condition. The quality is outstanding and everything was exactly as described. I’ll definitely keep coming back!

Fast shipping and product works! I'm so glad I found this option. Steady 1-2 lbs per week weight loss for 2 months. Not a fan of the complicated payment portal.

some of the products were ok others not as good. The Reta from this vendor did not work versus my previous place. I also was disappointed with the email response time and fact no refund or another vile where sent after using 2 that were not good. I bought 4 products from this company and have since gone elsewhere.

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.
