Start with a simple peptide hold-time estimate.
Run a research-use estimate for a curated vial peptide, see the likely hold time and top risk drivers, and open the deeper model detail only when you need it.
Only supported vial workflows should be treated as in-domain.
Unsupported dosage forms, missing identity, and out-of-scope chemistry should stop the workflow early instead of producing a false sense of certainty.
Defaults are there to lower first-run friction.
If you do not know the stress conditions yet, keep the defaults and let the uncertainty score stay visible.
The next step is still wet-lab confirmation.
Estimates are there to prioritize pH, appearance, RP-HPLC, and LC-MS, not to replace them.
How It Works
The first run should feel lightweight.
Single-peptide mode is the default, with blend mode hidden until you need it.
Volume, solvent, and temperature stay up front. Stress settings stay hidden until you need them.
The first view focuses on hold time, confidence, and the top drivers before model detail.
Supported Boundaries
Honest scope is part of the product.
- Curated lyophilized vial peptides
- Single compounds and binary blend scenarios
- Aqueous reconstitution only
- Explanation-heavy hold-time estimates with explicit uncertainty
- Clinical compounding, dosing, or patient-use advice
- Formal shelf life or expiry claims
- Topicals, strips, finished nasal workflows, and non-peptide products
- Metal-complex and heavily modified analog submodels
Guardrail
Not a clinical expiry engine.
Peptide Holdtime is a research estimate for curated RUO workflows. It does not make sterility claims, patient-use recommendations, or formal shelf-life declarations.
