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.

Only reason it’s not 5 stars is because it took 2 1/2 weeks to get my order, customer service is great

Our lab is a steady purchaser of ultra high quality peptides from Prime Labs. They consistently deliver exactly what they advertise and we consider them a key member of our research team. If you are considering additional material providers, you will not be disappointed working with Prime Labs. We are not affiliated with them personally in any way, this is the objective review they deserve.

The website is easy to use, and the prices are good, especially when they have sales. Everything came wrapped with bubble wrap, so no chance of breakage. The COAs are good, too.

Initially I was hesitate to order because I’ve had had a bad experience with another peptide company, but decided to try out prime labs and I was surprised because all the Facebook reviews showed that they had shipping and I was shocked the second time I’ve ordered with them and the order has been with me within a few days! Great customer service, thanks guys!

I’ve made several purchases from Prime Lab and will continue to exclusively use them. With the exception of one order, all have been fulfilled and delivered very quickly - several shipped same-day as purchase! The quality is great and the prices are right. You can stack promos with sale prices, which is a huge bonus when bulk ordering.

I haven’t had to time to prepare or even use the peptides I ordered, so I’ll review those super important details as soon as I can give an honest review. But as far as everything else it’s a 5 out of 5 stars.

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.
