These dosages are a helpful guide, not a prescription. Every clinician is expected to do their own due diligence before prescribing.
No established human dose
The evidence is preclinical only. PubMed lists rodent studies of cognition, nerve injury and a Huntington disease model, plus zebrafish work. No human trial, human pharmacokinetic data or human dosing was found. Two foundational Washington State University papers carry retraction notices (2025) and an expression of concern (2021). One rat Huntington model study found no benefit. FDA states it has identified no human exposure data for dihexa acetate. A 2018 systematic review of experimental non-human studies (PMID 29733881) is the best single summary of the animal evidence. Papers that use dihexa as a reagent to turn human stem cells into liver cells are in vitro work and are not clinical evidence.
