Test-C Duration

O.K., want to run some test C or E.
How long will my test levels be abnormally elevated after my last dose?
Doc likes to run bloodwork on me periodically and I don’t need him freaking out, I’m on HRT! So I need a time frame that I can go by IE; 2weeks, 4 weeks… I may add EQ to the mix also, same applies there…
Thank you, Tim

The half-life of test C or E is roughly 8-10 days. Use that number with how much you’re using each week to determine how long you need be off before getting the test done.

Say you inject 500mg per week then you’re looking at a total body concentration of something like an 800mg concentration each time you inject. If you injected today and your HRT dose is 100mg/wk then you’d want to stop about a month in advance. To be safe we’ll assume a 10 day half life. You can use this example to adjust accordingly.

1st 10 days: 800 down to 400mg
2nd 10 days: 400 down to 200mg
3rd 10 days: 200 down to 100mg

JC,
Thanks for your reply, that;s exactly what I needed to know. Now how about EQ? Does that elevate test as well?
