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.
Most of my recommendations for considering yourself an advanced steroid user are self-explanatory. Basically, my worry here is that no matter how many cycles you´ve done, if you´re losing half of your gains from each cycle, then you have a lot of work to do to figure out what you´re doing wrong after your cycles end. There´s really no way around that fact & if you´re not keeping half of your gains, then something is going wrong when you end your cycles. Before you jump into an advanced cycle, with multiple compounds and drugs, you need to get your post cycle in order. If you´re losing more than half your gains from every cycle… then something isn´t in check. You aren´t an advanced steroid user you´ve just used a lot of them. But, if you keep most of your gains from each cycle, and meet the other 3 criteria for being advanced, then this cycle is for you!
500 mg/week . In my opinion, this is a reasonable minimum for an actual steroid cycle. I see little point in suppressing the HPTA but probably failing to get much gains out of it, as is the usual outcome for any dosage much less than this. Again, because testosterone aromatizes to estradiol, an aromatase inhibitor may be required to avoid estrogen-related side effects. No one, I think, will fail to see substantially improved gains at this dosage level compared to natural training, but the rate of improvement may be slow. Eight weeks, however, is sufficient even at this amount for a quite significant improvement, unless of course one has trained for enough time at this usage level to have gotten most of what the individual can obtain from it.
