Test suspension is the most potent form of testbecause 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. You can see that Suspension is the true king steroid. as there is no ester attached, Test-Suspension does not carry a traditional half-life in an esterified sense; it can't as there is no ester. Nevertheless, it does possess a total activity time, giving it a half-life of slightly less than 24 hours. This is a very short lived half-life.
