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.

Easy access and training instructions to the app. It says it will be 3 days and within 2 days it is at our door step. We have had symptoms as recommended you have to do the research and either increase magnesium, collagen, fiber and/or protein. Nausea has came with dosage changes. My spouse and I are using the Trizepitide and are very pleased with our results thus far.

I wasn’t able to place an order this time because of a new payment platform that was launched. I tried a couple different payment options and both would not go through so I ended up having to purchase elsewhere. That is unfortunate.

If you’re considering purchasing peptides, I highly recommend this company. My experience with Prime Lab Peptides has been outstanding from start to finish. Their team is knowledgeable, dependable, and clearly committed to delivering high-quality products. The ordering process was simple and secure, and shipping was impressively fast. Overall, this company will from now on be my go-to supplier.

I’ve ordered from this company several times, and up until now, everything was excellent. Shipping was always fast, the products were reliable, and I genuinely felt confident ordering from them. However, when I tried to place an order today, I was redirected to an external site that immediately asked for personal information. That was an instant red flag. I’m not comfortable providing sensitive details through a third-party link, especially when this wasn’t part of their process before. Because of this unexpected change, I no longer feel secure ordering from them and will be looking for a new, trustworthy site moving forward. It’s disappointing after such a good track record, but customer safety should never be compromised.

Updated Review: Updating my review — everything has been resolved. There was a duplicate charge due to confusion with the crypto payment process, but the team handled it quickly and issued a refund without any issues. Great customer service and communication. I appreciate how they took care of the situation and made things right. I will continue doing business with them. 👍 I have sent multiple emails regarding a duplicate crypto payment for Order #16199 and have received no response. Due to confusion during the MoonPay checkout process, I accidentally completed two payments of 319.34 USDC each, totaling 638.68 USDC, while my order total was only $331.00. I have already provided full details and transaction hashes, and MoonPay has confirmed both payments were successfully delivered to the wallet generated during checkout. The order has already been delivered, yet I am still waiting for support to resolve the overpayment. I was planning to continue doing business with your company, but the lack of communication is very concerning. I expect a prompt response and resolution. If I do not hear back soon, I will have no choice but to escalate this matter further.

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.
