### ★★★★★ customer service actually answers

*Matthew Q. — Jun 23, 2026*

Had a question about which payment options they took and emailed expecting to wait a day. Reply came back in under an hour and they walked me through paying with Zelle. Order itself was smooth and arrived fast.

### ★★★★☆ quick shipping

*Brandon L. — Jun 17, 2026*

Two days from order to door. Box was plain and nothing rattled around. Would order again.

### ★★★☆☆ fine, just pricey

*Janet B. — Jun 9, 2026*

Product and shipping were both okay. Just noticeably more expensive than a couple other domestic sources I've used for the same thing.

### ★★★★★ took a chance and glad i did

*Tara F. — Jun 4, 2026*

I'd been buying from another vendor for about a year and got tired of slow restocks, so I gave Core Peptides a try after seeing them recommended a few times. First order was CJC-1295 and Ipamorelin plus some bac water. Processed same day, shipped USPS Priority, landed in three days on the dot. Packaging was discreet and the vials were well sealed with no damage. I asked support a question about stock before ordering and got an answer within a couple hours, which honestly sold me more than anything. Reordered since and it's been the same experience both times.

### ★★★★☆ solid catalog

*Dylan S. — May 30, 2026*

The selection here is huge, they had two blends I couldn't find anywhere else. Shipping was quick too.

### ★★★☆☆ good vendor but where are the COAs

*Wesley L. — May 24, 2026*

No real complaints about the product or the shipping speed, both were fine. But I had to email them to get a certificate of analysis and even then it wasn't tied to my batch number. For the price I'd expect that on the product page already.

### ★★★★★ fast and accurate

*Josephine O. — May 19, 2026*

Ordered BPC-157 and TB-500 on a Tuesday, had it by Thursday. Order was exactly right and the vials looked clean.

### ★★★☆☆ good vendor

*Brittany B. — May 14, 2026*

CJC-1295 order showed up fine and the vials looked right. Pricing has been creeping up though.

### ★★★☆☆ plain packaging, slow restock

*Andrew G. — May 9, 2026*

Product is fine and arrived ok. Just a bland unmarked box and the GHK-Cu I wanted was backordered two weeks.

### ★★★★☆ will use again

*wesley\_fit — Apr 30, 2026*

Solid all around. Ordered TB-500, came in three days, packaging was secure. Customer service answered my question quick.

### ★★★★★ fast and clean

*Miles D. — Apr 18, 2026*

Two day delivery, semaglutide reconstituted perfectly clear. Exactly what I wanted.

### ★★★☆☆ underfilled vial

*Kenneth X. — Apr 5, 2026*

One of two ipamorelin vials looked light compared to the other. Emailed them and they were polite about it but I'm knocking a star.

### ★★★☆☆ decent, COA gripe

*Matthew N. — Mar 22, 2026*

BPC-157 came quick enough. Wish more products had the COA posted upfront instead of having to ask every time.

### ★★★★☆ consistent quality

*Janet S. — Mar 9, 2026*

Tirzepatide order, my second from them. Same fill, same fast shipping. Glad I found a steady source.

### ★★★☆☆ slow email reply

*Mason M. — Feb 24, 2026*

Product was good but it took three days to get an answer to a simple shipping question. Otherwise fine.

### ★☆☆☆☆ Wouldn't reconstitute, wouldn't refund

*Ally — Feb 17, 2026*

I've been researching peptides for years. CJC-1295/ipamorelin and wolverine blends to be specific. I switched to core peptides hoping to save a little bit of money. horrible mistake. The CJC/Ipa blend was clumpy and wouldn't dissolve. It wasn't my bac water because I tried again with a vial from my previous brand, worked great. Worst part is that once I FINALLY got a response from customer service they were useless. No refund, blamed me, wouldn't take ownership. Their lab tests look a bit suspect too. I won't be ordering again.

### ★★☆☆☆ Where are the real certificates?

*SJG — Feb 17, 2026*

Start with the good, lots of options\! —but they around of stock of what I want.  Then I click on their COAs and it’s just an auto generated image, if they do have real 3rd party testing? please correct me if so…

### ★★★★☆ good experience

*Holly B. — Feb 11, 2026*

Ordered retatrutide, shipped same day since I beat the cutoff. Showed up fast and well packed.

### ★★★★★ impressed

*Sandra D. — Jan 29, 2026*

First time ordering, BPC-157/TB-500 blend. Arrived in 3 days, vials looked perfect, COA emailed when I asked.

### ★★★★☆ reliable so far

*Hannah Z. — Jan 17, 2026*

Four orders in, never a problem. MK-677 and ipamorelin both consistent. Site says UPS but it always ships USPS, minor thing.
