From reading multiple post on half lives of multiple steroids im still slumped to some point. Im going to use a ridiculous number to prove my point so that we can understand when to start pct when doing certain gear.

Lets say week 1 i inject 1000mg of a certain drug that has a 7 day half life. This is telling me that in 7 days i will still have 500mg in my system.

Most of us inject weekly so after 7 days i pop another 1000mg which means now at day 8 i have 1500mg in my body. Without going through all of the math at the end of my cycle i should slowly approach the ending point of around 2000mg on my last pop, not the important part of this post.

I have just popped my last injection say monday jan 1st to make things easier and this is where things start to get hazy. Lets say currently monday january 1st i have 2000mg of this drug in my body. On monday jan 8th (7 days later) i should have 1000mg left correct? Wouldnt that mean that in another 7 days (january 15th) it would be completely gone/degraded?

If not...and it just keeps halving over each week it could take a year for every bit of the drug to be completely out of my system.

So my question is at what point/level of drug do your start pct and i know this is vague depending on which gear your on but how do you know to start pct when there could still be way too much gear left in your blood stream because of extremely long half lives........

Hope this makes sense
