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.

Ordering was very easy and the product was delivered on time with great communication along the way. I have been purchasing from another reputable company but found Prime Lab Peptides more affordable. Also when I had questions I emailed them and Sofia was great answered my questions promptly and in detail. I just tried the product waiting for results but I will be ordering again shortly. I needed to test the waters so to speak not knowing more than what I have read about Prime Lab Peptides but they have lived up to and earned the great ratings they’ve received for their product and customer service!

I ordered 2-30 mg vials and they arrived quickly and were packaged very nicely! I did have a question for them and they were very quick to answer my question!! I have not tried the product yet, so I can’t give any input as to how it affected my research!

Easy finding, ordering, and delivery. Very good follow up on delivery status. Products are accurately labeled and after a few weeks of use have had zero quality issues when compared to known samples. One issue that was easy to solve was that the stopper had collapsed so could not draw up sample. Easy fix with an 18g needle. Excellent supplier. Well Done!!

Ordering was easy, delivery was on time, packaging was great. I just received the order and my test subject had the first dose with no issue. It’ll will be a couple days before I can comment on quality, but I’ll update this post if it’s not as expected. So far 5 stars.

Prime Lab has great selection for all my research needs. My first order was a little slow to receive which, was ok but my last order was here by the next day. Also, what I like they have a reward program that gives you points you can use for your next order. Prime Lab has won my business, so thanks again and I will be making a 3rd order real soon!

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.
