Reconstitution math, sourced dosing, and honest pharmacokinetics for 30 common compounds

One page per compound: the reconstitution math, sourced dosing and titration schedules, honest pharmacokinetics (a curve only where human data exists), storage guidance, and the primary sources, with deep links into the calculators. These are references, not recommendations.

Compounds with no published human pharmacokinetics (CJC-1295, AOD-9604, BPC-157, TB-500, GHK-Cu, MOTS-c, KPV, Epithalon, DSIP, Semax, Selank, Melanotan I, 5-Amino-1MQ, Humanin, SNAP-8, NAD+, Glutathione) are deliberately absent from the chart above; their pages explain what is and is not known instead of plotting a rodent number as if it were a human one.
