Correct me if I'm wrong but isn't enanthate the same thing as heptanoate?

It's a synonym of E^ Technically Hep's ester drops off on 10. E drops off 10.5. Hardly a difference and as you had in mind, virtually the same.

I'd like to add to the OP. The The dose of the androgen should also determine post cycle start times. Example: If you took 2 bodybuilders, 1 on 500mg/wk Test E and the other on 2500mg/wk Test E, in 10-14 days time the 500mg/wk bodybuilders total T will be far less than the 2500mg/wk bodybuilder. Therefore changing the PCT start time. Food for thought for the viewers out there.

I should also point out Stan Depot does not have a half-life simply due to the fact that it's un-estrified. It contains microcrystals that will dissolve slowly and once they've all dissolved the levels of the hormone will fall pretty rapidly.

Great post LK.

Thanks LK, we should sticky this, because this is a good reference chart.
