Shandong Shengyuan Peptide Technology is a China-based vendor offering both retail and bulk peptide sales. The catalogue is narrow, listing just three peptides, and the single available certificate of analysis doesn't cover any of them. Pricing data is limited to one observed offer. The site has been verified as operational, but no community feedback has been captured.

Testing coverage
We hold lab certificates for this vendor, but none of them correspond to a product currently in their catalogue — so we cannot confirm what is in any vial you could actually buy. Testing scores zero until that mapping exists. This one is on us as much as them.
