The Sigma-Aldrich-Named Peptide Storefront
Credibility concern recorded. The source reference remains available for verification and correction.
A China-based ecommerce site selling research compounds while presenting itself as Sigma-Aldrich (Shanghai) Trading Co., Ltd.
Field notes
The storefront routes visitors from a research-compound catalog through warehouse selection, shipping choice, and an external card-payment page. It lists China-origin shipping at $25 standard or $50 express, and offers a separate affiliate mechanism promising 10% commission while customers receive 5% off. The page names several testing and review services, but the extract does not establish whether those affiliations or the stated 99.5%+ purity figures are independently verified.
