I could be wrong, but I believe IDS buys their bulk raw from Ergpoharm (or LPJ). Same stuff inside the capsules, it just comes down to an issue of dosages meeting label claims.
I don't know about IDS, but I do know that HDT 1-AD can be severely underdosed! A few caps were tested @ 28mg for what was supposed to be a 100mg cap!!?!? HDT bought 1-AD directly from Ergopharm too...so just because Ergopharm is the raw prodcut doesn't mean the comapny is dosing correctly.
