How to Read Interaction Data

Interaction Types

Synergistic

Peptides work through complementary mechanisms and may enhance each other's effects.

Neutral

No known interaction. Peptides act on different pathways and can typically be used in the same protocol.

Caution

Overlapping mechanisms or side-effect profiles. Consider using one or the other, or consult a provider.

Avoid

Combining is not recommended due to overlapping receptor activation, increased adverse effects, or lack of additional benefit.

Confidence Levels

High confidence

Supported by clinical studies, established pharmacology, or prescribing information.

Moderate confidence

Based on preclinical data, pharmacological reasoning, or limited clinical evidence.

Low confidence

Theoretical or anecdotal. Limited evidence available. Use with additional caution.
