You can't just take the weekly dose and add that to the dosage of that day while ignoring the esters. In this case, it comes close to working out because the half-life of test e is close to 1 week. However, if using test with another ester, adjustments will have to be made.
From Bill Roberts:
The amount to use is the amount that is on average taken in one half-life of the drug, plus the injection amount that will ordinarily be used.
So for another example, letâ??s say someone is planning on using 600 mg/week of testosterone enanthate, taken as 200 mg three times per week.
If figuring the half-life at 5 days, then on average the amount taken per half-life (per 5 days) is 5/7 of the 600 mg. That works out to an average of 429 mg taken per 5 days.
So the frontload amount is that amount, plus the usual ongoing amount of 200 mg.
If being highly exact this would work out as 629 mg, but as 600 mg is a more convenient figure, this would be more than close enough. Thereâ??s no problem in rounding the number a little.
So on Day 1 the injection would be 600 mg. This would not produce unusually high levels, but instead would promptly get levels to where they need to be.
