I think that AndroDrive being more Pregnenolone and DHEA based should call for a PCT than would support adrenal hormones. Hexarelin on top of being a GH peptide also raises ACTH allowing the adrenals to fire up it's own Pregnenolone production again. Pregnenolone and DHEA both lead to increased GH so a peptide for GH seems like a smart idea to me. Lastly I think this would be a great addition to help maintain gains post cycle when using AD combined with something else (AD alone wouldn't make much gains), the anabolic and thermogenic effect of GH could keep gains lean following a cycle of AH and ADD for example.

I would still have other stuff in PCT, but Hexarelin seems like an unusual but smart addition for PCT when something like AD is being used.
