My one gripe is the certificate of analysis they sent wasn't tied to the actual batch I received, it read more like a generic reference doc. Purity numbers were there but I'd rather see my own lot tested. Shipping was reasonable, about four days domestic. Decent enough for the price, just wish the paperwork matched the order. ### ★★★☆☆ just okay *Rachel S. — Jul 1, 2026* Product was fine and arrived intact, but the plain padded envelope with no cold pack made me a little nervous in summer heat. ### ★★☆☆☆ took way too long to get here *Hunter K. — Jun 18, 2026* Order sat on processing for almost a week before a tracking number ever showed up. When it finally arrived everything was fine, but two emails asking for an update went unanswered. For a vendor this small I expected to hear back faster. ### ★★★★☆ good vials fair price *matthew.o.sourcing — Jun 4, 2026* Pricing on their BPC-157 beat what I usually pay and the vials looked clean with consistent fill. Shipping was a couple days slower than I'd like but nothing major. ### ★★★★★ 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.
