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!

Delivery was quick with the QR codes right on the box for easy access and reinforcement of instructions. Wonderful experience & don't forget the great discounts offered!! Thank for your research.

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.

I’ve ordered four times twice I got it asap other two times they were sold out they don’t let you know it’s impossible to get a hold of them , it’s hit or miss and than it’ll take weeks to get a product or even a response if you want reliability than then this isn’t the company. Products are good when you actually receive them, product sold out again and can’t get a replacement I have to chalk the 85$ as a loss this time .

I've used this company in the past plenty of times, but this time without issues, but for my most recent order, they've refused to give me a refund after their delivery time didn't come on the day it was supposed to. They mentioned some bs about how delivery days don't count on weekends. I told them I've received my package on a Saturday before so how do you explain that? I was ghosted and no one reached out to me after that. Completely disappointed.

I submitted an order on December 9, 2025. Upon sending an email to confirm my order, I was informed that it would take 2 days for the payment to clear. After following up with another email requesting a confirmation note, one was provided, but the goods had not yet been shipped. Despite sending multiple follow-up emails, I have been receiving unsatisfactory responses. I advise against entrusting them with your money. As of January 4, 2026, I have yet to receive my goods.

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.

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.

Not shipped after 11 days

I ordered on December 6th, and as of today, December 17th, my order has not been shipped. I have sent several emails, and they keep saying that my order will be shipped within 48 hours, but it has been well over 48 hours.

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.
