### ★★★☆☆ does the job

*Sierra H. — Aug 5, 2026*

Packaging was secure and the order matched the site. Nothing stood out either way, just a standard transaction that took about a week.

### ★★★☆☆ decent middle of the road vendor

*Ryan K. — Jul 27, 2026*

I have ordered from Research Peptides twice now and both times have been fine but unremarkable. The peptides themselves seem good and the vials are sealed properly. Shipping has been the weak point, around a week to ten days each time even though they are domestic. Customer service answered my one email after a day. They put a COA up on the site but it is a product-level certificate, not specific to the batch I received, which I would prefer for the price. If you are not in a rush they are a perfectly reasonable choice.

### ★★★★☆ no real issues

*Samantha D. — Jul 18, 2026*

Ordered the GHK-Cu, arrived in about a week, vials crimped clean. Cold pack was a little soft on arrival but the order itself was fine.

### ★☆☆☆☆ still waiting on a reply

*Wade E. — Jul 9, 2026*

Placed an order and one item shipped out of stock without notice. I emailed customer service four days ago about a partial refund and have not heard back. Disappointing for what is otherwise a normal looking store.

### ★★★☆☆ pricing is fine, shipping less so

*Robert E. — Jul 1, 2026*

Their TB-500 is priced reasonably compared to a couple of other vendors I checked, and the site was easy to navigate. Shipping was the slow part, took about nine days. Average overall.

### ★★★☆☆ ok but plain packaging

*Matthew O. — Jun 22, 2026*

Vials were fine and fill looked correct. Box itself was pretty bare bones, just a padded mailer with one cold pack that had mostly thawed by the time it reached me. Not a dealbreaker but worth mentioning.

### ★★★★★ great support

*Connor Y. — Jun 13, 2026*

I had a question about stock before ordering and they emailed me back within about ten minutes. Order showed up six days later, everything packed neatly with an ice pack. No complaints here.

### ★★☆☆☆ slow to ship

*Emmett N. — Jun 4, 2026*

Took eleven days before the tracking even updated. It got here eventually but that is longer than I expected from a US site.

### ★★★☆☆ COA was generic

*Allison Z. — May 27, 2026*

Product arrived fine and the vials were sealed well. My only gripe is the COA they linked wasn't tied to my actual lot number, it was a general one for the product. Would like to see batch-specific docs.

### ★★★★☆ solid reorder

*Jonathan K. — May 19, 2026*

Third order from Research Peptides and the BPC-157 vials looked the same as the last two batches. Consistency is what keeps me coming back.

### ★★★★☆ solid source

*Caleb R. — May 9, 2026*

Quick shipping on my TB-500 order, vials sealed and labeled, COA sent on request. Nothing fancy but it works.

### ★★☆☆☆ no ice pack on a warm week

*Melissa H. — Apr 3, 2026*

My BPC-157 shipped with zero cold pack during a hot stretch. It was a long transit too. Emailed them and the reply took four days.

### ★★★★★ happy customer

*samuel487 — Mar 2, 2026*

Third order with them. MK-677 always arrives quick and the vials are consistent. Support answers fast when I have asked anything.

### ★★★☆☆ out of stock issues

*Kayla W. — Feb 5, 2026*

Half my cart was sold out by the time I checked out and the retatrutide I wanted has been listed as backordered for weeks. Stock could be better.

### ★★★★☆ GHK\-Cu came through clean

*Gabriela H. — Jan 14, 2026*

GHK-Cu vial was sealed and the powder looked good, reconstituted to a nice clear blue. Packaging was plain but did the job.

### ★★★☆☆ decent, prices creeping up

*Michael D. — Dec 12, 2025*

Been ordering tirzepatide here for a while. Still reliable but the prices have gone up noticeably since last year. Shopping around now.

### ★★★★☆ Quick order, both peptides tested well

*Mason Hart — Dec 7, 2025*

Grabbed MT2 and TB-500 from Research Peptides for upcoming trials. Both arrived in 3 days with proper cold packing. COAs look good - MT2 at 98.4% and TB-500 at 97.9% purity. Pricing was competitive. Will order again.

### ★★☆☆☆ slow shipping

*Jasmine D. — Nov 18, 2025*

Took eleven days and tracking did not update for most of that. The CJC-1295 was fine when it finally arrived but the wait was rough.

### ★★★★☆ ipamorelin order

*Christina U. — Oct 29, 2025*

Ipamorelin reconstituted clear, no floaties. Took six days to arrive which is fine for the price. Would order again.

### ★★★☆☆ COA not batch specific

*pamela.m.research — Oct 6, 2025*

They emailed a COA but it was a generic one, not tied to my actual lot number. Product looked fine but I would have liked the matching paperwork.
