Yeah, but they both come in packs of 24 (not sure if the primatene tabs are easily split in half though as a one and a half pills would be the equivalent μmoles to one bronkaid).
$5.00 for 24 tabs of HCl ~ 1510 micromoles total ~300 μmole/$
$6.20 for 24 tabs of SO4 ~ 2300 micromoles total~370 μmole/$
So yeah, you do only get about 75% of the alkaloids per mg, but the Bronkaid's higher doesage makes up for it, right?...micromoles, lol, it just dawned on me how small of a unit we're talking about.
EDIT: So this means that 25mg of Eph SO4 ~ 19mg of Eph HCl.
