- Lyophilized Appearance
- Compact white or off-white cake occupying one-third of vial floor; does not shift when tilted
- Loose powder, yellow/gray discoloration, or dispersed across vial walls; shifts easily
- Legitimate lyophilization produces a dense, cohesive structure. Loose powder indicates improper freeze-drying or filler substitution
- Reconstitution Time
- Dissolves completely in 60–90 seconds without agitation; crystal-clear solution
- Requires swirling or shaking; cloudiness, particulates, or residue remain after two minutes
- Delayed dissolution or cloudiness signals contamination, incomplete synthesis, or engineered filler designed to mimic peptide appearance
- Certificate of Analysis (COA)
- Batch-specific HPLC purity ≥98%, mass spectrometry confirming 9,117 Da molecular weight, endotoxin <1 EU/mg
- Generic COA with no batch number, missing mass spectrometry data, or no endotoxin testing
- Absence of batch-specific verification is the clearest indicator of unverified or counterfeit peptides. No COA means no traceability
- Packaging Integrity
- Vacuum-sealed vials, tamper-evident caps, desiccant packets, cold chain documentation
- No vacuum seal, loose caps, visible condensation inside vial, or moisture exposure during shipping
- IGF-1 LR3 degrades rapidly with moisture exposure. Compromised packaging renders even authentic peptides ineffective before use
- Supplier Transparency
- Provides third-party lab verification, lists synthesis facility location, offers batch retesting upon request
- Vague sourcing claims, no synthesis location disclosed, refusal to provide independent lab verification
- Legitimate suppliers disclose synthesis facility accreditation and offer independent retesting. Opacity on these points signals unverified sourcing
- Price Point
- $80–$150 per 1mg vial from verified suppliers; reflects synthesis cost, purification, and quality testing
- Significantly below $60 per 1mg or wildly above $200 per 1mg without corresponding purity documentation
- Pricing far below synthesis cost suggests dilution or counterfeit; excessive pricing without third-party COA suggests markup without quality basis
