What carries over from Peptide Sciences
- Same compound coverage. TB-500 is one of the most-cited compounds in tissue signaling research.
- Stricter compliance posture: server-side researcher attestation, geo-restricted shipping enforcement, no human-use implications anywhere on site.
- Batch-specific Certificate of Analysis with every order — not blanket lot docs.
- Privacy-respecting checkout: crypto + Zelle, no marketing-database opt-in, no resale-targeted retargeting.
