### ★★★★★ small shop but they got it right

*Brandon B. — May 21, 2026*

First time ordering from a smaller name and honestly it went better than expected. Box arrived sealed, vials filled to the line, and the COA was right there in the package.

### ★★★★☆ quick and clean

*Jenna A. — Apr 22, 2026*

Domestic shipping was fast, three days. Vials sealed, labels straight, COA in the box. Reordering.

### ★★★☆☆ was out of stock

*Sandra W. — Mar 15, 2026*

Wanted tirzepatide but it had been out of stock for a couple weeks. Ended up getting ipamorelin instead which arrived fine.

### ★★★☆☆ fine, nothing special

*Caleb Y. — Feb 4, 2026*

Ordered BPC-157, came packaged ok and on time. Just an average experience honestly, nothing stood out.

### ★★★☆☆ Mixed experience with Semax order

*Spencer Bauer — Jan 14, 2026*

Ordered Semax and KPV together. Semax arrived fine but KPV vial had a small crack in the rubber stopper. Contacted them and they shipped a replacement but it took 8 days total to resolve. The actual peptides tested well once I got usable vials. Wish their QC caught the defect before shipping.

### ★★★★☆ good support

*Joseph H. — Jan 9, 2026*

Had a question about my retatrutide order before it shipped and they answered same day. Helpful and friendly.

### ★★☆☆☆ vial looked underfilled

*Jason D. — Dec 18, 2025*

My MK-677 vial seemed light compared to what I ordered. Hard to be sure but it didn't look right next to my last one.

### ★★★★☆ Reliable source for BPC\-157

*Heath Pearson — Dec 15, 2025*

This is my third order of BPC-157 from Pacific Research Labs and they've been consistent every time. The COA shows 98.7% purity which is what I need for my protocols. They include bacteriostatic water which is convenient. Shipping took 5 days but that's reasonable. Only gripe is their website checkout process is a bit clunky - had to re-enter payment info twice. Product quality makes up for the minor inconvenience though. Their batch testing documentation is thorough and they clearly take quality control seriously.

### ★★★★☆ Great combo deal on CJC and GHK\-Cu

*Clara Jennings — Dec 1, 2025*

Bought CJC-1295 and GHK-Cu as a bundle during their holiday sale. Both products came with individual COAs dated within the last month. The GHK-Cu had a beautiful blue tint which indicates proper copper binding. CJC reconstituted smoothly with no particulates. Their packaging uses pharmaceutical-grade vials with crisp labels. Customer service answered my dosing calculation question within a few hours. Prices are middle-of-the-road but quality seems worth it. Tracking was accurate and delivery was on schedule.

### ★★★★★ my go\-to now

*Jack C. — Dec 1, 2025*

Third order from these guys. Semaglutide and GHK-Cu both reconstituted clear, packaging has been consistent every time.

### ★★★☆☆ COA not batch specific

*Paige K. — Nov 12, 2025*

The certificate they sent looked like a generic one rather than tied to my actual batch number. Emailed support and they took a few days to reply.

### ★★★★☆ no complaints

*Angela J. — Oct 29, 2025*

CJC-1295 order arrived in about five days. Lyophilized cake intact, COA included in the box.

### ★★☆☆☆ plain packaging, no cold pack

*Melissa S. — Oct 7, 2025*

Tirzepatide showed up in a padded envelope with no ice pack. It was a warm week here so that worried me a little.

### ★★★☆☆ shipping was slow

*Brenda W. — Sep 21, 2025*

Took about nine days to arrive which is slower than I'm used to. Product itself was fine, vials sealed and labeled.

### ★★★★☆ solid for the price

*Janet V. — Sep 3, 2025*

Ipamorelin came in well sealed and the price was a bit lower than the couple of other places I checked.

### ★★★★★ COA matched the batch

*Gabriel Z. — Aug 19, 2025*

Ordered BPC-157 and TB-500. COA was batch-specific and matched the vial labels. Will be back.
