Koipeptides Reviews 15

Ordered 3 vials of GHK-Cu from Koi after seeing the recent research on it and the product
quality is excellent. Vial labeling is clear, batch number printed right on it, COA matches the lot.
Shipping was 3 days to Texas. Their support team responded to my order status query the
same day. This is now my go-to peptides supplier.

The Retatrutide vials I received were in excellent condition. The lyophilized powder looked consistent and well-prepared, with no signs of degradation. Reconstitution was quick and effortless, and the order included a COA with detailed HPLC results. Very satisfied with the quality and would purchase again.

I've been ordering from various suppliers for years, and Koi stands out for its dependable service. Orders arrive on time, products are well presented, and the entire process feels professional from start to finish. Their team has always been helpful whenever I've had questions.If I had to point out one area for improvement, it would be pricing on a few specific products. I've noticed similar options available elsewhere for less. Still, the convenience, fast delivery, and overall experience keep me coming back. It's a solid company that I have no problem recommending.

Have nothing bad to say. The combination of Canadian-friendly sourcing, transparent and easily available COAs, fair pricing once you factor in the free delivery and crypto discount, and quick turnaround makes Koi the easiest recommendation in this space. If you're into research peptides and on the fence, this is definitely worth a look.

Quality is genuinely top of the line, no complaints there. Only thing I'd suggest is better tracking notifications. I had to manually check Canada Post a few times because their update emails were sparse. Small thing but improvement would be welcome.

This was my first time ordering research peptides and I was honestly pretty nervous about which company to trust. Did a ton of research before picking Koi and I'm glad I did. The site walks you through the products clearly, COAs are right there, shipping was fast (got mine in 4 days), and everything came packaged really professionally. Doesn’t feel sketchy, which I was expecting after reading several Reddit threads on how to buy peptides online.

Worth every dollar. Their KLOW blend is something else. The convenience of the blend versus stacking individually has saved me time on documentation alone. Purity has been on point across three separate orders now.

Paid with BTC, got a nice discount, order shipped the next morning. Has been an easy choice for me.

Ordered Sunday night, got it Tuesday afternoon. Tirz showed up in great shape, vials sealed properly, ice pack still partially frozen. Will order again 👍

Great stuff! Orders show up when they say they will, the products are what they say they are, and if something's off they actually pick up the phone. Fifth order for GHK-Cu placed last week.

I had a really specific question about my BPC-157 before I ordered, about something most suppliers either don't know or don't bother answering, and the person on the other end actually took the time to explain it properly. Didn't try to talk me into a bigger order, didn't paste a generic response, just answered the question. I've ordered four times since then. The quality has been consistent and same fast shipping too. There's something to be said for a company that treats a first-time buyer the same way they'd treat a returning one.

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.

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.

Verified the lot number with the lab they listed before I placed the order for Tirezepatide. Everything checked out. Been with them since.

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.
