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.

Yet again, Prime Lab has come through with perfect order fulfillment for our research lab. We depend on them and they deliver. Highest quality materials, at the right price and unmatched customer service. We evaluated several material sources and did in-depth research before landing on Prime Lab. It was the right decision!

Great Product Great Company!

I have been ordering products from prime Labs for several months now and can’t say enough good things about their products and the company! I am achieving the results I’m looking for! I ordered on Tuesday evening and my product arrived safely packaged Friday morning! Any questions I have are answered immediately by their customer service ( Thank you Magally!) the discounts are fantastic, they beat their competition by far! I will definitely continue doing business with Prime Labs!

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.

This company provides great products and quick shipments! I currently had a situation with the product ordered and felt like I had been baited and once baited, I felt the quality of the items I had purchased didn't seem so great. I did research and felt very targeted in the wrong way. I had spent money on bulk and thought I had been scammed. All evidence seemed to point in that direction. The customer care team worked diligently to solve the concern. They apologized for the circumstances that had me concerned. They investigated and helped to bring understanding on the matter. It did take a matter of a week to resolve, but in the end, they resolved my concerns. Where I was a very skeptical after using this company in the past, they made me a loyal consumer again! I learned a valuable lesson throughout this situation, that at every distributor, even at Walmart, and Amazon things can get delayed, mixed up, and seem hopeless. And sometimes solutions to our concerns do not happen on our timing, but what's important is the willingness to make the customer happy... and this company has that! That says a lot to me in my opinion! A great company stands behind their product and knows customer satisfaction is key! The route to excellence takes integrity, and this company has it!!

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.
