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.
In either case, both men and women, Anavar can be used for far longer than most oral anabolic steroids due to its low liver toxicity rating and further as it does not appear to taper off in benefit as fast as many other oral anabolic steroids. The majority of Anavar users will supplement for 6-8 weeks but longer durations of 12 weeks are not uncommon, especially during female contest preparation time. Keep in mind, the leaner you are the greater the results will be, meaning, they will be far more pronounced; for this reason most women will choose Anavar during the latter half of their diet to reap the greatest reward.
