Each box of Klenprime 40 holds 50 tablets, every one carrying 40 mcg of clenbuterol hydrochloride. Nothing in it is a hormone: clenbuterol belongs to the beta-2 adrenergic agonist family, the same class as several bronchodilators, and it sits in the weight-management section for its thermogenic and stimulant character rather than for any androgenic action.
Eminence Labs makes it as a plain oral tablet, so there is nothing to draw up, mix or refrigerate. Of the two strengths the Indian manufacturer puts under the Klenprime name, this is the lower one.
