I had a look what that is, turns out its 65% glycerol + 35% silicon dioxide.
Do you use that in a shake? Have you thought about using pure 100% glycerol? It's more concentrated than HydroMax and probably a lot cheaper. It also avoids ingesting silicon dioxide.
As long as the evening caffeine doesn't cause issues. You could pair the evening dose with ~500mg theanine for improved sleep quality. It's a big dose but theanine is fairly harmless.
IMO the natural L-form phenylalanine is best. IIRC D-phenylalanine inhibits an enzyme involved in dopamine production. I've only ever used L-phenylalanine.
Just fyi, agmatine shares the same "anti-adrenaline" property as clonidine and tizanidine. So if you ever increase your agmatine dose or use it more frequently remember it will potentiate those other drugs. Agmatine
could be worth using in lower doses (~500mg) more frequently - eg with your sodium ascorbate...or at least once @ AM, once @ PM to benefit from it's anti-addiction/anti-withdrawal effects.
It all depends how you feel about it really, i'm just offering ideas. Agmatine (and theanine) both act as a "buffer" from benzo tolerances, and proactively repair things (neurogenesis via BDNF & GDNF).

this post interesting, basically anabolics help by blocking anti-catabolic hormones like cortisol/estrogen.
Less cortisol, less weight loss. Theanine and Agmatine both protect/reduce cortisol (directly and indirectly).
