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.

Consistency
Been a customer for a few months. Products are as described, backed with COAs and available customer support.
Highly recommend.

Great customer service
I made my first order and it duplicated. I messaged them and they sent back the first payment and fixed it. Really super easy to work with.

A provider you can trust!
I have purchased with Northline Labs a bunch of times now and been very pleased with the process, and products. In a time when it's hard to find trustworthy sourcing, you can trust Northline!

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.

I’ve ordered 4 times from Northline
I’ve ordered 4 times from Northline; every order was on point except one order my package was either stepped on or smashed when I got it from UPS. They re-issue right away no questions.

Wish I’d read the negative reviews…
Wish I’d read the negative reviews before ordering. Worst experience after having ordered from a few other peptide companies. To begin, paid for two day shipping and didn’t receive for 10 days as other reviewers have noted. But most egregious is that none of the vials have batch numbers that correlate with the COA published on their website and no printed COA came with my order. Dose written on the Reta vial was a completely different dose than the vial ordered. I would never ever feel safe using and conducting research with any vials that come from this company. Just outrageous, epically given that I spend $750 on my order.
Order #32506
Update: not sure why they’re pretending not to know about this order considering they’ve emailed admitting their mistake re wrong vial being sent. This still however does not address my concerns re safety of vials as batch numbers and lot numbers don’t correlate to what’s published on the site. This is the only peptide company I’ve seen have this discrepancy and not include COAs with orders sent.

It's Chinese untested chemicals
Their reviews all have American names and horrible English that's been translated from Chinese. This company is NOT third party tested. They are a Chinese company shipping from over seas with untested chemicals. I tested the Retarutride and it was only 42% pure. This is a health risk.
Update: I sent all the proof to northline labs and they doubled down that their reviews are authentic when it's a name like Jeff Kyle and the message is like "Purchased Times many and Can't I get enough! Incredible generosity of this peptide man journey!"

Bought northline labs retatrutide 20mg and it was delivered from a home address. I have sent numerous emails and texts asking why and to send me cert on this product but keep getting the run around. I’ve taken the product for over a month and don’t believe it is legit. I previously purchased from peptide science but they went out of business. So I know what I should be feeling with the product. Very disappointed

Reta
I paid extra for 2 shipping and didn’t receive the product for almost 10 days. Tried email and calling the company no answer. their Reta Is fake been taking it 3 weeks and absolutely no benefits or improvements on hunger curve. I’ve taken Reta from another company and had results in 2 weeks. Do not waste your money or time on their overpriced fake products
