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

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.

I have purchased twice from Prime Lab Peptides and was a great experience with great product. The new paying system has been down low though- I can’t get any of the three payment options to go through. I had to start buying my product from another company. However, if prime lab peptides were to open up more accommodating payment options I’d surely go right back to spending my money there. Thanks 😊

Fast shipping and product works! I'm so glad I found this option. Steady 1-2 lbs per week weight loss for 2 months. Not a fan of the complicated payment portal.

So far, everything is going great. The price was least expensive. It was the delivery that I had a little hiccup with, but everything was fixed and it took two days instead of 12 hours, but the product actually works so far if the pressing my appetite as it should, and I’ll let you guys know a little bit more after a month from now

Great resource for all your peptide needs

The Experience searching and finding the correct peptide was great! The site was easy to use and the communication once the order was placed was amazing! The only reason I didn’t give 5 stars was the checkout process. There were a lot of steps, confusing signup process and a lot of declining from the payment processor without reason… the third party payment processor was not easy to work with. The peptides came quickly and well-packed. Despite the frustrations with checkout, I will definitely shop here again.

it was a really good experience working with you guys. I can’t say much about the actual peptide itself since it hasn’t even been a full week yet I thought the reconstitution guide was a little confusing. I was unsure of how much backwater to put in. It would be really helpful if you guys had a video instruction or a little bit more links to go to with extra procedural role demonstration

I am still evaluating efficacy but I was really happy with the shipping and communication regarding product arrival. I am also happy with the instructions sent via email on reconstitution and use

Love the product but shipping varies. My first order took almost 3 weeks to get to me. My second order arrived 3 days after purchase. I purchased my 3rd order 3 days ago and haven't received a shipping confirmation email yet so I think shipping this time is going to be a similar fulfillment time frame closer to my first order than my second. But as long as you order ahead of time it's not an issue if it runs a little later on fulfillment. But product seems to be great. Research test results have been promising so far. Price isn't the cheapest on the market but it's definitely competitive! Will order again for sure. Just make sure you keep in mind that sometimes shipping isn't super fast.

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.
