As Masteron-Propionate is an excellent bodybuilding contest anabolic steroid the majority of who supplement will do so during this period and generally towards the latter half of the contest prep when they are already lean; remember, the leaner you already are the more pronounced the benefits will be. As a Propionate based anabolic steroid there is a very short half-life associated with Masteron-Propionate and to be effective we must administer it on an every other day basis.
Most will find 50mg every other day to be the minimal dosage if the desired effects are to be obtained with 100mg every other day being far more optimal. Yes, you can use more than this but you will rarely find anyone using more than 600mg-700mg per week and more often than not such doses are overkill. For those who choose to use Masteron-Propionate you’ll find it stacks well with most anabolic steroids and common stacks often include items such as Trenbolone, Testosterone and Winstrol.
