Interaction Checker
Check the curated interaction dataset for the compounds in your stack.
Not exhaustive. This covers high-value pairs only and is a harm-reduction reference — not a complete drug-interaction database. Always verify with a clinician or pharmacist, especially for prescription medications.
Add compounds on the left to check for interactions.
Educational use only — not medical advice. The interaction dataset is curated for harm-reduction and is incomplete; many real drug, supplement, and food interactions are not represented. Confirm any stack with a qualified clinician or pharmacist.
About this tool
The interaction checker cross-references your stack against a curated dataset of compound-by-supplement and compound-by-prescription interactions. List what you take (peptides, hormones, supplements, and prescriptions) and the tool flags known interactions with severity and a short mechanism note. It is a starting point for research, not a green light to combine anything.
How to use it
- 1 Add each compound, supplement, and prescription you take.
- 2 Run the interaction check.
- 3 Review flagged pairs, their severity, and the mechanism note.
- 4 Discuss any serious flags with a clinician before changing anything.
Frequently asked questions
Is the interaction checker medical advice?
No. It is a reference tool that surfaces documented interactions from a curated dataset. It doesn't cover every possible combination, and it can't account for your full medical history. Always consult a clinician or pharmacist about interactions that matter for you.
What does each severity level mean?
Major means a documented risk of serious harm. Moderate means a meaningful effect on efficacy or side effects that may need adjustment. Minor means a small or theoretical interaction. Treat any major flag as a reason to consult a clinician.
