Most beauty-relevant
GHK-Cu
The cleanest starting point for a skin-focused audience. This is where peptide education feels most naturally at home on a beauty site.
Interesting but early
MOTS-c
An intriguing metabolic and healthy-aging topic, but still the kind of conversation that should sound more like careful education than beauty recommendation.
Interesting but early
BPC-157
High curiosity, high skepticism, and too much category confusion to treat casually in a founder-led beauty brand.
Prescription / medical class
GLP-1
A serious medication conversation that can intersect with beauty culture, but should stay clearly separate from ordinary skincare language.
Related, but not a peptide
NAD
Important in longevity and metabolism conversations, but not something Susie should group under peptides if the goal is scientific precision.
The right audience does not need Susie to flatten the ladder. They need her to make the ladder obvious.
How to use the ladder
- Start with the top: lead the public-facing section with the most beauty-native material.
- Mark the early topics clearly: if something is intriguing but still uncertain, say that early and often.
- Keep prescription content separate: readers should feel the boundary immediately.
- Use category corrections as trust builders: saying “NAD is not a peptide” makes the whole section stronger.
How the ladder affects what Susie can sell
The higher and cleaner a topic sits on the ladder, the easier it is to feature in beauty language. That is why topical skin peptides can eventually support product edits, while BPC-157, MOTS-c, GLP-1, and NAD should stay in education-first territory or outside casual commerce completely.
