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.

First, let me say shipping was upgraded for free. The peptide was nicely packaged delivered by FedEx my only concern was GHK-cu usually stings because of the copper & it did not. I mixed with 3 ML water and I didn’t get any sting ? This is my second shot, . Does that mean the peptide is not real? After this review prime labs reached out and offered their support, & also advised I should feel some sensation with this peptide. They sent me a replacement shipment that I received today. I am thoroughly impressed I’ll update again once I start using and can report results See updated review [https://businessapp.b2b.trustpilot.com/reviews/693366ee66d2118d1048b0c3/?locale=en-us&businessUnitId=681f7d9aaa0d32686abce823]

The website is easy to navigate, ordering was simple and being able to stack multiple discounts is amazing on top of already decent prices! My shipping was upgraded and shipping timeline and delivery notifications were on the dot. Discreet packaging was also nice, insulated and the vials were well protected from breakage. So far all is going as intended with the products.

Initially they corresponded quickly but I needed a refund as I ordered wrong peptide, Sophia cancelled it for me which was great but 8 days later still not refunded and last night she emailed me and said they never received funds but it was charged to my credit card. This morning I sent a photo of charge and still no response. I also reordered 8 days ago the correct peptides and it was charged to my card as well and still has not shipped out. Concerned I am scammed, hoping they respond. Seems most of the reviews have been well handled.

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.
