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!

Great experience overall! There is a wide variety of products available to review, and each listing includes clear descriptions and easy-to-follow directions. The entire process is seamless, from selecting products to checking out. Shipping is prompt, and tracking information is readily available, making it easy to monitor orders every step of the way. Highly recommend!

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.

This was a multi-order day for our research lab with Prime Labs and it all went perfectly as usual. We have come to depend on their high quality peptides for our research. They consistently deliver the quality products and services we demand.

The fact that my shipment delivery was upgraded to 2 day air verses the usual ground delivery! Makes a huge difference in when I receive my packages. My very first order took over a week which I had never had issue with other companies that I have used.

Who sent you a vowel of medicine to mix and inject without giving you the proper syringes? I've paid $163 and I got nothing to inject with so make that make sense.

I loved buying from this company! I bought my product, but roughly five days passed without it getting shipped out so I sent them an email about it. They said it's because the 'size' I wanted was out of stock, but they gave me a full refund and sent me a free bottle with a higher mg. I was very thankful and started conducting my research with the Tirzepatide 30mg. Everything seems to be going smoothly and all the symptoms points to a high purity vial of Tirz. I waited three weeks before leaving a review and I can attest that this product is of great quality. This was my first time buying a research peptide company and I'm glad this company was my first time.

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.
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.
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.
Reviews their authors deleted, and reviews taken down before the former profile closed, are excluded — republishing them would put back online what was removed.
A plain average of 1,276 ratings, every review counting once. No weighting, no recency bonus.
