— THE LAB —
One lab. Named, registered, accountable.
Every biologic we educate on comes from a single FDA-registered U.S. partner — screened, quarantined, and released with a Certificate of Analysis for every lot.
In partnership with


FDA-REGISTERED·CLIA-CERTIFIED·GMP/GTP-COMPLIANT
A trusted laboratory partner.
Most operators in this category source from anonymous resellers and aggregators. We chose a different path. Renvi works with a single, established laboratory partner — selected for the seriousness with which they approach sourcing, processing, and documentation. Their standards are the foundation of ours.
Where the science comes from is the most important compliance and quality decision in this category. We made it deliberately.
Why Renvi
Screened, quarantined, and verified — every lot.
Most operators in this category stay anonymous about who oversees the work and where the materials come from. We don’t. Two things sit at the center of how Renvi operates.
Lab-verified quality
One lab. One standard.
Our biologics are sourced and processed by a single, dedicated U.S.-based laboratory partner. Nothing in the supply chain is anonymous.
- Triple-layer donor screening & characterized, quality-verified tissue
- QR-code Certificate of Analysis released to documented spec
Renvi’s single laboratory partner is Regenerative Research Group (RRG) — an ethically-sourced, quality-verified biologics program. RRG supplies the biologic suite our independent providers may discuss with you.

— THE PROCESS —
From donor to recipient. Documented every step.
Why we made this choice.
One source.
Healthy, informed U.S. donors aged 18–25, with three-generation health screening and healthy, scheduled C-section births only — no smoking, alcohol, drugs, or vaping.
Real documentation.
100% chain of custody from donor to recipient, released with a Certificate of Analysis and full lot tracking on every batch.
Honest standards.
Processed in an FDA-registered, CLIA-certified, GMP/GTP-compliant U.S. lab — with no cell expansion (per 21 CFR Part 1271) and a 14-day quarantine plus full disease testing on every lot.
The U.S. standard we hold to
- ✓FDA-registered, CLIA-certified, GMP/GTP-compliant processing

- ✓Three-generation donor health screening; healthy, scheduled C-section births only
- ✓No in-vitro cell expansion, per 21 CFR Part 1271
- ✓Sterility and release testing on every lot, with a Certificate of Analysis
What we won’t accept
- ×Anonymous or overseas sourcing with little traceability
- ×Pooled material from multiple donors
- ×Cell expansion not permitted in the U.S. without specific FDA licensing
