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 was shown this concept by a nurse at a Dr's office. She has lost 40 pounds so far. Her biggest concern was the hair loss she was starting to experience. I did research on vitamins to take to hopefully bridge this myself. I understand why it happens. I just started Tirzepatide this week. I am, in the end, needing to lose 90 pounds. I understand Tirzepatide will help me with about 50. I was wondering if you have advice on what to take for that last 40? I saw there were different options.

Updated Review- I originally purchased two 30 mg vials of tirzepatide from Prime Labs back in September. My last review noted that I didn’t think the potency was nearly as good as other vendor I had been using. In November, their customer service team reached out after seeing my review. They acknowledged the quality issue and explained that improvements had been made. They offered to send me one 30 mg replacement vial—half of my original order—to demonstrate the upgraded quality and asked that I update my review if I felt it had improved. The replacement arrived within a few days of our email exchange, and the quality was much better this time. I genuinely appreciate when a company makes the effort to correct a problem, and Prime Labs did follow through. I’m giving four stars because although they did not replace both vials from my original purchase, the improvement in product quality and their willingness to address the issue deserve recognition.

Arrived quickly, just as promised. And then they placed another charge on my credit card! Don't check the VIP box, because you will be charged $35. They credited it when I inquired but my credit card company is replacing my card so I have that inconvenience to deal with.

Product arrived in a mailing envelope; some vials were secured in a vial box, which was appreciated. Three vials were rolling around loose in the envelope when there was room for them in the vial box. Hoping the product is good quality, shipping was fast!

Fast free shipping, excellent quality, friendly conformation email that offers support

Free fast shipping Discount code wasn't offset by shipping cost like other suppliers. Researching lowers doses is very affordable but not so much when researching maintenance or max dosages. For comparison a compounding pharmacy charges the same price for all dosages. Trizep 15mg x4 =$200 Prime Labs Trizep 30mg @ $120 x 2= $240

I’m genuinely impressed with my experience! My order arrived quickly, just as described, and the communication was excellent throughout. It’s clear Lab Peptides truly values its customers—and I love that they also support charitable initiatives. That kind of integrity really sets them apart. I’ll definitely order again.

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.
