What is a peptide stack?

A peptide stack is a combination of two or more peptides used together to achieve a specific goal. Stacking can produce synergistic effects when compounds target complementary pathways.

How does the interaction checker work?

The interaction checker cross-references known pharmacological mechanisms for each pair of peptides in your stack. Interactions are classified as synergistic, neutral, caution, or avoid, with an evidence tier (clinical, emerging, or theoretical).

What does the safety score mean?

The safety score (0–100) reflects the overall interaction profile of your stack. Synergistic pairs add points; caution pairs subtract 15 points; avoid pairs subtract 40 points. A score above 80 indicates a generally well-tolerated combination.

Can I share my peptide stack?

Yes. After building your stack, click Share Stack to copy a URL that encodes your exact selection. Anyone with the link can view the same stack and analysis.
