So I want to be fair here because I

So I want to be fair here because I really like this peptides company. Quality is excellent, no complaints on the products themselves, and the team has been responsive every time I've had a question. My only gripe and the reason I'm not giving five stars is that on my last order one of the vials came with a slightly bent cap. Still sealed and usable, the contents were fine, but it was a little annoying for the price point. I emailed them about it and they offered to send a replacement which I declined because it wasn't a big enough deal, just something to note. Solid company overall.

Pleasantly surprised

Pleasantly surprised. Ordered Friday afternoon expecting it Wednesday or Thursday and it showed up Tuesday morning. Vials looked exactly like the photos on the website which honestly isn't always the case with peptide suppliers. Will reorder.

Best peptides supplier in my

Best peptides supplier in my experience! Just got my second order this morning, four days from Toronto to my place in Halifax which I'm still kind of impressed by. Packaging was simple but everything was intact without any broken seals or weird residue. The Retatrutide I got last time worked exactly the way I expected based on what I'd used previously. I'll keep buying from them, there's nothing to complain about and the prices are a huge plus.

Been ordering research peptides in

Been ordering research peptides in Canada for almost three years and customs has been a nightmare with US vendors. Switched to Koi a month ago and every order has arrived at my doorstep in Calgary in 3 to 5 business days. The team also actually replies when you reach them out, which sounds like a low bar but you'd be shocked.
