Narrow Labs

Been using Narrow Labs for a few months now, mostly for Melanotan II studies. This latest batch came with a really detailed COA that included additional amino acid sequencing data which was super helpful for my documentation. Purity came in at 98.6% which is excellent. Reconstituted perfectly and the vial quality is noticeably better than some budget vendors I've tried. Shipping was 5 days, tracking updated regularly. Price point is fair for the quality. Only minor gripe is their website doesn't save your shipping address for future orders so you have to re-enter everything each time. Will definitely keep ordering for research purposes though.

Placed an order for MK-677, Melanotan II, and BPC-157 about three weeks ago for ongoing lab research. The MK-677 and BPC-157 both checked out fine - good purity according to the included COAs, dissolved cleanly, proper labeling. The Melanotan II however arrived with a manufacturing date that was almost 11 months old. Not expired technically, but I prefer fresher compounds for baseline studies. Customer service was okay when I reached out, they offered a 10% discount on my next order but I would've preferred a replacement. Shipping took 6 days which is middle of the road. Pricing is competitive but not the cheapest I've seen. They're not bad, just nothing that makes them stand out from the dozen other vendors I've tried over the past two years.
