SCOPE OF THE EVIDENCE
What This Report Does — and Does Not — Establish
This report supports
- Independent verification of the submitted sample
- Reported identity as Retatrutide
- Reported peptide content of 32.80 mg
- Reported purity of 99.892%
- Batch-specific third-party evidence for srt2609200357
This report does not by itself establish
- Results for other Signalyn Bio batches
- Sterility unless separately tested
- Endotoxin level unless separately tested
- Residual solvents unless separately tested
- Heavy metals unless separately tested
- Long-term stability
- Complete manufacturing traceability by itself
Scope of this result: Results shown apply only to the submitted sample and batch.
