Design a stack, with structural guardrails.
Click plates from the atlas to add them. PeptidesDB runs a rule-based conflict check and surfaces recognised synergies from the documented literature. Every selection is encoded in the URL — shareable instantly.
Conflict checks come from the schema. Multiple GLP-1 RAs, two GHRPs at once, melanocortin overlap, GH-axis with angiogenic peptides — every rule is deterministic, auditable, and visible at src/lib/stack-conflicts.ts.
When you add two plates that share a documented synergy in the YAML (e.g. GHRH + GHRP), the designer flags the recognised stack with the citation that supports it.
Conflict rules cover structural class-level concerns. Individual decisions about dose, timing, monitoring, and contraindications require your own literature review and a licensed clinician.
