Sustanon is made up of 100 mgs of testosterone decanoate which has a half life of 14 days. The next drug in Sustanon is 60 mgs of testosterone isocaproate which has a half-life of 8 days. The third drug is 60 mgs of testosterone phenylpropioate with a 6 day half life. And finally the last ester is testosterone propionate which has a half life of 4 days. So not only is it extremely difficult to map out the life of these different testosterone esters, but in addition, Sustanon is only dosed at 250 mgs per ml. This means that if you are using ampoules of Sustanon (the little bullet shaped class vial in the pic next to the box), you have no choice but to dose the drug in multiples of 250mgs.
Also, medical advice should be sought if the person has previously suffered heart attack, has a disease of the blood vessels or the heart, has high cholesterol levels in the blood, has clotting or excess bleeding problems, or has diabetes, kidney, or liver diseases. If the person has one or more of these problems, then an alteration of the dosage may be required. Medicines that can react with Winstrol are blood thinners or anticoagulants, diabetes medication, and insulin. Care should be taken while administering Winstrol with any of these medicines.
