Half life and PCT timing question... I don't get this stuff

[DecaKid]

here is the math i'm talking about:

if you shoot 2g's of deca how long does it take to leave your system. This is assuming after 1 half life, you have 1000mg's left; after 2 half lives you have 500mg's left; and so on. Define "leaving" system as 75mg's left.

so here's the equation: 2000*(1/2)^x=75 defn. x as number of half lives.
solving:
1) (1/2)^x=.0375
2)x*ln(1/2)=ln(.0375)
3)x=4.737 half lives or 10.1 weeks to almost clear your system.

if you work in previous injections at 2g's per week it comes to 13 weeks, i think, to almost clear your system

What am i missing here??!

What you are missing is that 2g's of deca per week is much higher than the standard dose.

Simply that deca is not test.
