Sourcing Fork
Which side of the sourcing fork the provider is on — legitimate 503A/503B compounding-pharmacy telehealth, or gray-market "research chemical" supply.
Why it matters
Peptides are a magnet for gray-market sellers labeling products "not for human consumption." The gap between a licensed compounding pharmacy and a research-chem vendor is the gap between medicine and a gamble.
How we assess it
We determine the actual supply source and its legitimacy.
- Legitimate 503A / 503B compounding-pharmacy sourcing
- Absence of gray-market or "research chemical" supply
Source types: The provider’s pharmacy disclosures and sourcing claims.
How we score it
Licensed compounding-pharmacy sourcing scores high. Gray-market "research chem" supply is the red flag this factor exists to catch and scores low.
