I have been using peptides now for about 2 months. And I have been purchasing from a few different vendors. Some have slow delivery. Have limited inventory. Or don't take credit cards. Northline had... Leggi di più

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.

Northline Labs

Not gonna lie, Northline Labs impressed me. Communication was on point and shipping was insane. I ordered and had it the next day. Everything came perfect. Super smooth experience overall. Definitely ordering again!

10/10 recommend

Didn’t think that the website was legit and was shocked with the amount of discounts I got and paying through Venmo, only took about 2 days for me to receive my order and everything was great and they even added a free product in my order

Top notch experience, Top notch quality.

I’ve had continued success with Northline. Products are properly labeled, backed with COA’s, and secured. I’ve tried other companies and the vials have no labels, you don’t know what is what, and they have no backing.

Northlines transactions show everything you are getting before you place an order and they arrive just as seen. Transactions are smooth and quick, and every step is emailed. Everything ships on time, even as they have expanded.

Extremely happy and will continue my journey with northline.

Worst customer service ever

Worst customer service ever. Who uses text messages anyway to complete a transaction and who uses Venmo to receive a payment. Someone answered me today today and said I will not be mailing you out anything. Do not trust this place. They don’t even have a legit mailing address.

So far so good…

So far so good, these peptides are more affordable and do have a COA per batch. I received my Reta and BAC last week. From order to shipment it took about 3 days including weekend to receive. I’ve taken one dose. I don’t have a lab to verify, and results are usually shown at 4mg-12mg according to trial study. but I’ll update in a couple months if there are no results.

Thanks, Ashlee - love how methodical the approach is. The COA-per-batch + research-grade reference makes a real difference vs guessing. Looking forward to your update.

A work with this business as a virtual…

A work with this business as a virtual assistant or creative and compeleted the task in full, including content creation from various pages that in the agreement in my first week and escalated as if I'm a fu**ing robot and social media management. Unfortunately despite delivering the work and following up multiple times since january 30, my payment was never received. I keep all communication professional and provided to work in good faith it also have documentation and competitive deliverables and final notice was sent but the issue remains unresolved. I'm leaving this review to share my experience, so other freelancer and contractors can make informed decisions and protect themselves. Peptides for growth,except when it comes to paying people.

Fake website and total scam

Fake website and total scam. Sadly I was a victim of it. The two addresses listed on their website are residential home addresses. The address on their Facebook is the US Postal Service address. Their COAs are fake, they have a fake trust pilot badge of excellent/5 starts when I am the first review to be written about them. I’ve called and emailed a million times and have gotten no response. They say you have to get your return approved before sending it and then there is no way for them to approve it since they won’t answer. Don’t trust them!!

E. — sincerely sorry no one connected with you. If you emailed hello@northlinelabs.org and didn't get a response, please try once more — Gmail occasionally filters our category to spam, and we read every reply within hours. We genuinely want the chance to address whatever happened with your order.

A couple of clarifications for anyone else reading: Northline Labs is a US-based company; our shipping origin is our fulfillment partner, not a private residence. Every batch we ship is third-party tested at 99%+ purity, and the Certificate of Analysis for each lot is published on the corresponding product page — anyone can pull it up by lot number. Trustpilot reviews are collected and rated by Trustpilot, not by us; the full review history is visible on this profile.

Please email hello@northlinelabs.org with your order number and we'll work the case directly. — Northline Labs Support Team
