Informasjon om virksomheten
Skrevet av virksomheten
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.

Negative
Negative. Send the wrong order. Last month and. Yet no possible solution. Too much money to throw away. I won't purchase again. Still seeking refund.
Update. The company reached out and will hopefully have it resolved in a day or two. Thank you.

Very happy with Northline
I was feeling overwhelmed trying to figure out which company to use for peptides after buying in clinic for $$$. I followed advice on Reddit and other online forums recommending Northline and I’m happy. Great quality and service.

Ordered Reta and NAD
Ordered Reta and NAD. Although shipping was a little delayed I’m happy with the Reta. Customer service has been great from day one. Haven’t started my NAD as I advised I needed to reconstitute with saline as opposed to the back water. Have recommend this company to several friends

First batch ordered
I just ordered my first group of peptides from this company. Shipping on their end was super fast. Dropped off at ups a few hrs after I purchased. We will see how it goes and if it goes well I wont hesitate to order from them again.

Affordable, fast.
Prices are some of the most, if not the most, affordable, out there. I received my order within a few days with standard shipping. Everything was as expected. No complaints. Will purchase again!

Shipping and product quality is good
Shipping and product quality is good! However, customer service is poor. It takes days for them to respond back or they don’t respond at all. I would ask about wholesale or ambassador perks, they responded once but the other times did not get no response.

Hi Cynn, thank you for the kind words on shipping and product quality — and the honest feedback on support. You are right that response times have been uneven during a fast growth stretch, and we have been actively fixing that. On the wholesale/ambassador inquiry: please email hello@northlinelabs.org with "Wholesale follow-up" in the subject line and we will get you a real answer the same business day. We appreciate you giving us the chance to make it right. Northline Labs Support Team
