I’ve ordered from 3 peptide sites and this is the only one where I could actually see COAs and get fast answers. Peps arrived fast and well packaged. So far so good.

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.

Simply the best. I’ve tried a few places and this one stands out. They actually reply, they care, and the product feels right. It’s not just another sketchy supplier, you can tell.

Had a pretty technical question about formulation, and the answer I got was super in-depth. You can tell they actually know what they doing. That kinda attention makes you feel like you can really trust them

Grabbed 3 vials of Tirze 30mg in bulk, used SAVE20 code. Got the USPS free shipping, landed in 3 days. Bubble wrap was tight, and they tossed in a 10ml bac water taped up like a little extra gift. Support checked in all along to make sure the freebie made it safe. Little touches like that go a long way.

Soooo happy with this company. There was a shipping mess up that wasn't even their fault, and they still fixed it and upgraded me to overnight. They always throw in little perks for repeat costumers, send thank you notes, and answer emails super fast (like under 30 min)! My research legit saved my life. I get emotional thinking about how things were before vs now.

Ordered a few times now, always impressed. Quality’s always there, peptides show up fast, sealed tight and got COAs with ‘em. You can tell lab standards are solid. Don’t see myself ordering from anyone else.

Pep veteran here, have used roughly 5-6 peptide companies. This one is on another level. The cakes are prestine, clean, and effective. I placed an order, did some more reaseach, then placed another order a few hours later. They combined my orders, refunded the shipping on both and applied free shipping since I hit the free shipping reward. The prompt and professional customer service is gold stanard, only if comcast would take a page our of your book. Thankyou!

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 1,277 ratings, every review counting once. No weighting, no recency bonus.
