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!

Great experience overall! There is a wide variety of products available to review, and each listing includes clear descriptions and easy-to-follow directions. The entire process is seamless, from selecting products to checking out. Shipping is prompt, and tracking information is readily available, making it easy to monitor orders every step of the way. Highly recommend!

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.

There was a big promotion happening when I placed my order which caused a delay in shipping. I did receive emails keeping me updated on when it would ship. They expedited shipping once my order was ready to be shipped by upgrading it to 2 day. That was an unexpected bonus and much appreciated. I will update when I have some feedback on the product.

Prime lab is very responsive to questions and the customer service people are excellent. If I had one small criticism is that it seems that orders aren’t always processed promptly which can delay delivery a bit.

So far so good!! I literally ordered my research products 2 days ago & today they were at my door. I love the links they give me to the products I ordered with very helpful research knowledge on how to study the products. I'll start a customer if they seem to be working.

I saw all the great reviews so I chose this company to make my first purchase. Honestly, I thought i had been scammed at first, because they claimed 2 day shipping and days later I still had no word of my purchases being shipped. I reached out and they assured me that it was just taking longer as they were overwhelmed with cyber Monday orders. When I received my products they were packaged well and they had even upgraded my shipping free of charge. I highly recommend this company.

It’s scary ordering online these days and knowing who to trust. However fast shipping and reasonable prices on peptides, I took a chance here w Prime Lab Peptides. To be honest shipping was delayed and not as quick as I had hoped for. BUT every email I sent had a speedy response and in the end I did receive my products and customer service made it worth the wait. So yes, I do recommend this company.

this stuff works GLP-2 and GLP-3
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 1,276 ratings, every review counting once. No weighting, no recency bonus.
