Hey guys,
I came across something recently that has raised a question.
I have examined the testosterone levels in the body of two scenarios using a geometric series formula.
scenario 1: A patient given 500-mg injection of testosterone enanthate (with a half-life of 10.5 days)
every week will metabolize ~33.3% of the drug between each administration.
Using the given information to calculate the levels of test. e. in the body after the
12th shot results in ~749.6mg

scenario 2: A patient given 150-mg injection of testosterone propionate (with a half-life of 4.5 days)
every 48 hours will metabolize ~55.6% of the drug between each administration.
Using the given information to calculate the levels of test. p. in the body after the
12th shot results in ~337.5mg
Attachment 124547
Conclusion: Although the total administered weekly dose of test. p. (525mg/week) and test. e. (500mg/week)
are almost equal. The presence of test. e. is ~2.2 times the amount of test. p. in the body after the 12th shot.
Question: what is the effect of this difference in the amount of the drug present in the body?
