USADA was given full authority to execute a comprehensive national anti-doping program encompassing testing, results management, education, and research, while also developing programs, policies, and procedures in each of those areas
Some research has explored whether AHK-Cu may help modulate 5-alpha reductase, the enzyme that converts testosterone to DHT

This mechanism amplifies existing HGF signaling rather than bypassing it: HGF Potentiation: Dihexa binds to HGF and stabilizes its active conformation, increasing c-Met receptor activation at physiologically relevant HGF concentrations Synaptogenesis: In vitro studies reported that Dihexa promoted new synapse formation at picomolar concentrations orders of magnitude more potent than BDNF in this specific assay Dendritic Spine Formation: Preclinical data suggested increases in dendritic spine density in hippocampal neurons, a structural correlate of learning and memory Oral Bioavailability: Unlike most peptides, Dihexa's small size and peptidomimetic structure may allow oral absorption and blood-brain barrier penetration Cerebrolysin: Multi-Neurotrophic Factor Cocktail Cerebrolysin is a standardized mixture of low-molecular-weight neuropeptides and free amino acids obtained by enzymatic breakdown of porcine brain tissue

After use, if needed, remove the remaining amount of the gel from the flip-top cap with a cotton towel or absorbent paper until visually clean and dry
Limitations include limited large-scale human clinical evidence, challenges in extrapolating in-vitro concentrations to in-vivo contexts, stability sensitivities (light, heat, alkaline pH), and variability in supplier purity
