that chart looks all kinds of wrong to me. if you are injecting 500mg of test a week, you should have significantly more than 70mg of test in your blood by week 10. also, the correct timing to start your pct is determined by the halflife of the compounds you take, which is largely determined by the ester attached to the steroid. so taking test prop will give you a very different time to start your pct than taking test c.
test c has a halflife of approximately 6.5 days, meaning that if injecting 500mg, after roughly 6.5 days there should be 250mg left in your body. for the sake of easier calculation, and erring on the side of caution, lets work with a halflife of 7 days, and a shot once a week.
week 1 500 mg
week 2 750 mg (500 injected + 250 left over)
week 3 875 mg
week 4 937.5 mg
week 5 968.75 mg
week 6 984.37 mg
week 7 992.18 mg
week 8 996.09 mg
week 9 998 mg
week 10 999 mg
as far as i know, you want to be under 50 mg of aas in your bloodstream before you start pct (this could be wrong, if it is, anyone please feel free to correct me), which would mean this:
week 11 499.5 mg
week 12 249.75 mg
week 13 125.87 mg
week 14 62.43 mg
week 15 31.21 mg
meaning that i would probably not start pct before the beginning of week 14 at the earliest, and not before week 15 if i had a limited supply of pct meds.
