### ★★★☆☆ 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.

### ★★★☆☆ Decent peptides but customer service lacking

*Isla Thompson — Sep 21, 2025*

Ordered KPV and Melanotan II for different research applications. The peptides themselves tested okay - KPV came in at 96.2% purity and MT2 at 97.5% according to their COAs. My issue is I had questions about storage recommendations and it took customer service 5 days to respond. That's just too slow for a serious research operation. Shipping was fine, about 4 days. Prices are reasonable. If they could improve their response times I'd rate higher. The products are decent but support matters when you're spending this kind of money.

### ★★★★★ no complaints

*Laura S. — Sep 15, 2025*

Semaglutide showed up well packed with a cold pack. Vials filled to spec and labeled clearly. Smooth checkout too.

### ★★★☆☆ support is quick at least

*Christina D. — Aug 27, 2025*

Had a question before ordering and got an email reply in like five minutes. Shipping itself was average, took about a week to land.

### ★★★★☆ good first order

*anthony.x.prep — Aug 9, 2025*

Ordered BPC-157 and TB-500. Both vials arrived sealed with the lyophilized cake intact. Asked for the COA and they sent it the next morning.
