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.

So I have never tried any glp anything before but I started with the glp-3 and it’s seriously been a rough start because I didn’t get sick the first three days but I’m currently on my second week and I was way less sick and after the sickness wore off I felt so good! I’ve always had depression well at least for the last 13 years.. especially seasonal depression. I am a mom of 7 and over the last two years I’ve literally felt so exhausted! I have been been more happy I feel uplifted and I have way more energy and focus. I’ve been in a drug recovery program for the last 4 years and since starting GLP-3 I forgot to even take my medication. I am so thankful to have the opportunity to help with the research of this product REN has literally made me feel so human again.

I placed my order on the cyber deal days. It was quick and easy to place an order. They received way more orders than they expected and they sent me a text telling me so and gave me a new estimated delivery time. I waited about a week after that date. Nothing. So I text them, got a quick response and they expedited my order right then and apologized with a nice discount on my next order. I recieved my meds within 2 days after that and the meds are working great.

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.
