shipping a bit slow this time
Emma T.

My earlier orders came in two or three days, this one took most of a week with slow tracking updates. Product was fine when it got here.

COA not batch specific
Hannah V.

The cert they sent was current but it wasn't tied to my actual batch number. Would prefer a real batch match. Shipping and packaging were good.

Narrow Labs - average experience overall
Veronica Soto

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.

half their stuff out of stock
Nicole Y.

Wanted Ostarine powder and Cardarine in one order and ended up only able to get one. Stock is hit or miss. What I did get shipped fast.

no card payment

Products fine, shipping fine, but I had to dig out Cash App to check out. No card or PayPal option is a hassle. Knocked a star for that.
