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.

Not gonna lie, I didnt get it at first. I saw “Research Use Only” and “Not for human consumption” and I was like… wait, I want tirzepatide for humans 😅 Took me a second to realize how it works. Anyway, glad I did’t skip it, quality is insane and like 40x cheaper than pharma brands. No regrets (of course I am a researcher)

I’ve ordered from Prime Lab multiple times now, and every experience has been consistently top-notch. The products are clearly high quality, always arriving properly packaged and labeled. Shipping is lightning-fast, and customer support actually feels human—quick replies and clear answers every time. Easily the most professional peptide supplier I’ve dealt with.

I had my doubts at first, like most people ordering peptides online. But Prime Lab changed that. Everything, from the site to the packagin feels professional. And if you’ve already placed your order and you’re wondering if you made the right choice: you did 🤘🏻

Just got my batch independently tested, and the HPLC results came back 0.3% above the stated purity on the CoA. That’s not just impressive, it’s almost unheard of. The analysis showed 99.883% purity versus 99.58% declared, with no detectable residual solvents or endotoxins, and a perfectly sharp single peak, zero degradation products. That level of quality control indicates advanced purification methods, likely involving preparative RP-HPLC and tight cold-chain compliance. Huge props to Prime Lab Peptides. As said to Sofia, you’re not just meeting standards, you’re quietly setting new ones. This is pharmaceutical-grade research material. I won’t go anywhere else. 🤝🏻

A few months ago, I barely recognized myself in the mirror. I felt sluggish, bloated, and honestly… old. Like I’d aged a decade in just a year. I started Retatrutide from Prime Lab Peptides with low expectations Ive been burned by false promises before. But this time? Everything changedddd!!!!! Within 2 weeks, I started dropping weight,fast!!!!! 10 lbs gone without starving myself wow Whatss that . After 5 weeks, I was down 24 lbs and people around me were asking “what’s your secret? 🤨” but me 🤫 But what really surprised me was GLOW 70mg. I added it to my stack after reading about its skin benefits and wow, my skin was clearer, tighter, and even had this subtle radiance I hadnt seen in years. One friend literally said, “You look like you reversed time.” But still 🤫🤫 I’m 37, but people started saying I look 30 again. No joke, this combo gave me back energy, confidence, and a glow I thought I’d lost forever !!! Prime Lab isnt just another sketchy supplier they changed my life. Everything came fast, clean, and exactly as described. You can tell they actually care about their quality. No underdosed vials. No headaches. Thank you If you’r o n the fence , this is your sign. I’m living proof it works See updated review [https://businessapp.b2b.trustpilot.com/reviews/68a7396fd247d9d64bdf50b9/?locale=en-us&businessUnitId=681f7d9aaa0d32686abce823]

People online kept raving about Prime Lab, so I gave in.Ok, I get the hype now. These guys are the real deal. Not some shady supplier that ships unlabelled vials, ignores your emails, or disappears after your payment. No gimmicks, no drama, just pure quality, every single time.

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