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.

I just received my order and only the BAC Water was delivered. I paid $121.50 to receive only the water? No, I want a refund or my Retatrutide.

This is a 5-STAR organization from top to bottom. I don't know what's wrong with people who leave bad reviews about FedEx SHIPPING issues. This has nothing to do with Prime Labs. We regularly use Prime Labs as a top notch supplier for our lab work. We have independently verified the quality of the products and they consistently surpass 99% purity, just a advertised. You can trust Prime Labs.

First time buying through prime labs au. Was waiting for 5 weeks. And I was the one communicating. They couldn't tell me when they were able to ship the product. Or what the hold up was. Not sure if this place is a scam or not. I asked for a refund and revieved it. Waste of time I could have used another more trustworth site and recieved them 3 weeks ago. Disappointed

I had an issue with my shipping however I was assured, but the Customer service rep that my order will be shipped shortly and I was happy about the updates that I received in regards to the mass amount of orders they had for Black Friday. So the communication with this company is awesome.

Ordered product and spent a week and a half have not even gotten a tracking number even though I’ve been continuously told that it would be within hours and I would receive my tracking order and my order was shipping out that day. I understand it’s the holidays, but with that being said, do what you say you’re gonna do and don’t give me the runaround. now I’m going to try to get charges reversed.

I ordered specifically because of the quick ship claim as well as price. Unfortunately 10 days later my order still hasn’t shipped although they did take the money. Multiple emails w promises of shipping 24-48 hours, then will ship today via fed-ex and “we will send tracking” all false promises. Save yourself the aggravation and order from somewhere else. Now I have to spend Monday before Christmas sending proof emails to my bank to have the charges reversed.

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.
