### ★★☆☆☆ broken bottle, had to pay to return it

*Vivian I. — May 30, 2026*

One of the two dropper bottles showed up cracked and leaking. The annoying part wasn't the breakage, it was being told I'd have to cover return shipping to get it sorted. Felt backwards for something that wasn't my fault.

### ★★★☆☆ fine but the price went up

*Adrian G. — May 24, 2026*

Bought from them before and the Ostarine was the same as last time, packaging was solid. Just noticed the per-bottle price crept up since my last order. Still got the testing docs though.

### ★★★★☆ COAs for every batch

*victoria895 — May 19, 2026*

Ordered the Cardarine and they had a batch-specific COA posted right on the product page. Bottle was bubble wrapped, arrived in five days. No complaints.

### ★★★★★ quick shipping, COA matched

*Grant P. — May 9, 2026*

Terse review: ordered RAD-140, shipped fast, lab report lined up with the batch. Reordering.

### ★★★☆☆ plain packaging, product ok

*carolyn.l.biohack — Apr 27, 2026*

Box was pretty bare-bones and the vial just had a basic label, but the YK-11 itself looked fine and the COA was on the site. Middling, does the job.

### ★★★★☆ dependable vendor

*Corey H. — Apr 14, 2026*

Ordered MK-2866, arrived in five days, packaging was solid and the label had everything I needed. Good experience.

### ★★★★★ happy with the COAs

*Daniel Y. — Apr 1, 2026*

I always check the third-party report before buying and theirs are current. Cardarine came clear and properly sealed. Quick delivery too.

### ★★★★☆ easy reorder

*Miles Q. — Mar 19, 2026*

Second time ordering LGD-4033. Site was easy to use, shipping quick, vial labeled with batch info. Would recommend.

### ★★★☆☆ slow to reply to email

*Zachary D. — Mar 7, 2026*

Took about three days to get an answer to a question on my order. Not terrible but I've had faster. Product and shipping were fine.

### ★★★★★ price went up but still worth it

*Vivian P. — Feb 23, 2026*

Noticed prices crept up a bit since my last order, but the lab transparency and fast shipping keep me coming back. Ostarine arrived sealed and clean.

### ★★★★☆ good packaging

*Robert O. — Feb 11, 2026*

Stenabolic showed up double-bagged and bubble wrapped. Nothing leaked or shifted. Took about a week.

### ★★★★★ reliable every time

*Reid W. — Feb 2, 2026*

Fourth order. Shipping speed and packaging have been consistent, and they always have a lab report to point to. Trust them.

### ★★★☆☆ out of stock a lot

*Sean Q. — Jan 22, 2026*

Wanted the RAD-140 twice now and it's been out of stock both times. When I did get an order through it was fine, just wish they kept inventory up.

### ★★★★☆ no complaints

*Roger P. — Jan 13, 2026*

Ordered Andarine, came packaged well, labeled clearly, arrived on time. Does what a good vendor should.

### ★★★★★ free shipping is nice

*Mark S. — Jan 4, 2026*

Crossed the $75 threshold for free shipping and still got it in five days. COA available for the MK-677. Good vendor.

### ★★☆☆☆ vial seemed underfilled

*Rachel L. — Dec 22, 2025*

My 30ml of Cardarine looked a little short of the line. Could be my eyes but it bugged me. Shipping was prompt though.

### ★★★★★ Excellent quality across the board

*Melissa Nguyen — Dec 14, 2025*

I've been using Proven Peptides for about 8 months now and they've become my go-to supplier for research purposes. Recently ordered BPC-157, MK-677, and GHK-Cu for our lab and everything arrived perfectly packaged with detailed COAs. The MK-677 showed excellent purity levels (99.2% according to their third-party testing) which is exactly what we need for our studies. Shipping was fast, customer service answered my questions about reconstitution within a few hours, and pricing is competitive. I particularly appreciate how they clearly label everything as research-only compounds. Will definitely continue ordering from them.

### ★★★★☆ solid source

*Victoria I. — Dec 13, 2025*

Been ordering the LGD off and on. Liquid always looks clean, shipping is reliable, prices are reasonable. Happy customer.

### ★★★★★ Premium GHK\-Cu for dermal research

*Todd Jenkins — Dec 7, 2025*

Ordered GHK-Cu from Proven Peptides after reading good things about their quality control. Product exceeded expectations. Arrived in 4 days with excellent packaging including ice packs and desiccant packets. The COA showed 99.3% purity from an accredited lab. Reconstituted perfectly in bacteriostatic water - completely clear solution with no cloudiness. Been using it for dermal research applications and the results have been consistent. Price is fair for the quality. Customer service was professional and answered my storage questions quickly. Will definitely order again for future research.

### ★★★★★ great customer service

*Hannah U. — Dec 5, 2025*

Emailed about a shipping address mix-up and they fixed it within a couple hours. Responsive and friendly the whole way.
