I started out with just one peptide and now use a few different ones from Northline. Shipping is fast and customer service is great. The only thing I wish they would do is use larger vials for the hig... Leggi di più

Product Works. But I bought the The Mot-C and the BP-157 and there was no water to reconstitute the powder on either. This was a reorder for me. Twice no water. I think if you order stuff that needs t... Leggi di più

Quality products. Used several peps from Northline and every one have been great. Reta has shown great results and CJC-IPA provides the flush that indicates it’s working. Northline is my trusted suppl... Leggi di più
Dettagli dell'azienda
Scritti dall'azienda
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.

I got everything I asked for
I got everything I asked for, the exact stack I needed. The price is unbeatable to other markets. My girlfriend works at a clinic where a monthly stack is 16k a month. For a normal buyer trying to get into peptides this is the place!

Great experience overall
Great experience overall. Ordering was simple, shipping was fast, and the company had clear product info and solid communication. Products arrived well-packaged and as expected. Like most peptide companies, you still need to do your own research on usage, but from a service and reliability standpoint, this one stands out.

Great customer service and support
After issues with UPS delivery, I finally received my first order of LIPO C from Northline. First off customer service with shipping was phenomenal. We emailed back and forth and they always responded. LIPO C is great and really works well for my research. I will be purchasing from Northline labs again.

The peptides are superior quality
The peptides are superior quality. They ship fast and are packed with care. I had an issue with my last order because UPS delivered it to the wrong address. But I filed a claim with them to resolve. Northline responded immediately and offered their help. Definitely a great experience everyone.
