Excellent quality across the board
Melissa Nguyen

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.

Premium GHK-Cu for dermal research
Todd Jenkins

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.

BPC-157 arrived but took forever
Robert Drake

Ordered BPC-157 for research and while the product itself seems fine based on the COA, the shipping experience was frustrating. Took over 2 weeks to arrive even though I paid for expedited shipping. When I contacted customer service about the delay, it took 4 days to get a response and it was just a generic 'your order is processing' message. The peptide appears to be quality product and packaging was secure, but the lack of communication and slow fulfillment makes me hesitant to order again. There are other vendors with similar pricing who ship much faster.

Solid TB-500 source
Adam Cole

Ordered TB-500 for research and it came quickly. Packaging was discreet and professional. COA looked good, though I wish they included more detailed batch info. Overall happy with the purchase and would order again.

Good experience with a few minor issues
Lisa Chang

Been using Proven Peptides for a few research compounds - specifically their GHK-Cu, CJC-1295, and MK-677. Quality seems solid based on the COAs they provide and our initial testing. My only complaint is that the website checkout process was a bit clunky and took longer than expected. Also had to reach out twice about shipping updates before getting a response. That said, the actual products arrived in good condition and appear to be exactly as described. Pricing is fair for what you're getting.
