Testosterone is the undisputed king of steroids mainly because it is safe, elicits rapid mass and strength gains while maintaining libido, a sense of well being and energy. Pure Testosterone comes in a water based aqueous form (Suspension) and also in a solvent/oil based form (Test Base). Testosterone suspension is the most potent form of testosterone because it does not possess an ester. Esters are calculated into the steroid weight therefore esterfied steroids are not a true mg for mg of free hormone. 100mg of suspension is 100mg of free hormone! Enanthate in a solution is only 72mg of free hormone per 100mg.
