Co-administration notes from the literature

Verbatim summary text pulled from each compound's profile data. Researchers studying Epithalon and Testagen have published these mechanism-level observations. Not a co-administration recommendation.

Evidence level: mechanistic only

Khavinson pineal tetrapeptide (Ala-Glu-Asp-Gly; AEDG). Commonly paired with Testagen as part of the broader Khavinson "bioregulator protocol" covering pineal/circadian-aging (Epithalon) alongside testicular-aging (Testagen). Mechanistic independence; additive in the Khavinson framework.
