Northline Labs is an independent United States supplier of research-grade peptides and bacteriostatic water. We work with researchers, laboratory professionals, and biotech operators who need consistent quality and predictable supply. Every batch we ship is third-party verified at 99%+ purity. The Certificate of Analysis for each lot is published on the corresponding product page before the order moves — no waiting, no requesting. Weekday orders typically ship same-day via UPS, and we run a standing buy-one-get-one-50%-off offer across the catalog. We answer customer emails in hours rather than days, and we read every reply. Lot quality, transparency, and responsive support are the three things we work hardest to never miss — and the reason most of our customers come back.

A bit over priced compared to other companies I have purchased from. I only order if they are giving an extra discount on top of what they have now. Wish they were more competitive with their pricing.

I ordered Reta . Bc I was on brand Tirzepatide 15 mg from lily ..I went to 10 mg dose of Reta.. I had no result .. they are responsive and ship quickly . They claim the Reta is from a Texas lab . Their address in Minnesota but seems to have ox
Ownership in Canada . I would be wary of a company that uses a cofe of « the bearded gorilla « the owner I think is the bearded gorilla .. any way most of their spokes people look like they are on anabolic steroids and androgens They had a moron chiropractor advise you to use Reta and Tirzepatide together ( an Md is really gonna prescribe research pharmaceutical ) ?? . But to check first w your Md . I think think their peptides might be ok as they are easy to get . I think the Reta was horse feathers . Any way beware of medical advice from the drivers seats of Ubers etc . .. I find that hysterical .. and chiropractors and guys pumped up on steroids . Which is what most of their spokespeople look like . They are a new company and seem quite popular .. don’t know and don’t think they are scammers … but be wary of the source and quality

I did not feel anything whatsoever. Very disappointed, I feel I got scammed. I have taken semaglutide in the past prescribed so I am familiar with what I should have felt. I literally didn’t get any affects.

High quality material. Fast shipping. Quick helpful, responses from customer service. I couldn't ask for any better!

I had many questions when I first started using peptides. I reached out to get information on storage, use and reconstituting. I received a personal and detailed response which was much appreciated.

Absolutely loving my results from Reta, MOTC, and NAD+ and I am even doing lower doses and many online BROS recommend. I did a lot of research before hand for quality 3rd party lab testing with great pricing and Northline Labs delivers both. I will definitely order again.

I’ve ordered twice now from this company. Pleased with the efficiency of processing the order and timely updates. Packages have arrived without damages and without any issues. Highly recommend!

I've been receiving Northline Labs peptides. KLOW, MOTSC, RETA. Orders are received quickly. No issues with quality. Honest review though, the rubber stoppers in the vials leave very little room to draw my peptides and I bend a lot of needles.

Reply from Northline Labs
I have made multiple orders/purchases and each time they arrived on time and in great condition. No complaints here. I will continue to order from Northline.

Order to delivery was TWO DAYS! My second order from Northline. Very happy with the product and will continue to order. Only suggestion would be to ship 50mg in bigger vial than 10mg.
