Please don't give bad advice

The esters in sust do NOT work independantly of each other.
2Xwk is fine mate.
Personally i shoot i 1xwk on cruise.
Sustanon 250 contains a number of esters of testosterone with different durations of action. The esters are hydrolysed into the natural hormone testosterone, as soon as they enter the general circulation.
A single dose of Sustanon 250 in males leads to an increase of total plasma testosterone, with peak level reached approximately 24-48hrs (tmax) after administration. Plasma testosterone levels return to the lower limit of the normal range in males after approximately 21 days.
