Got exactly what I ordered, and fast
Ordered some peptides from Northwest Peptides and it was exactly what I expected. Shipping was really fast, faster than I figured it would be. The product quality was great too. No issues with anything. I'll be ordering from them again.

Checkout Frustrations
Every time I try to make a purchase, something goes wrong. Either I get kicked out because I don’t answer the questions, which should be at the top and not the bottom because they’re easy to miss, or the coupon code I’m using gets removed. Even after it went through the first time but I was forced to redo the payment info because I forgot to answer the questions. And then there’s a notification saying I can’t use the coupon code because it’s been used too many times. That is really frustrating. It just happened again today so I purchased from another supplier.

Great product!
My experience with NW Peptides has been great. Did my own individual research beforehand for peace of mind. Couldn't have asked for more as I'm currently on week 3 and down 8 pounds!
