    Not to sound like a dumb**** but what exactly does the halflife of a drug mean? I know what in normal termonoligy it means the amount of time for a substance to decay to 1/2 the original amount. For drugs is it the amount of time 1/2 decays in your system?

    It's how long it takes for the Drug to reach it's full strength into your system before it starts declining.

    Ah, ok. So if i inject test. enthanate on one day, 10 days later it will be at its peak, then decline from there for another 10 days? Makes sense, seems like its a long time though.

    No...Well Yes, you've got the therory right, but Enanthate is about 4.5 I believe, 10 is more like the "Active" life..meaning how long the drug remains in your system....The problem is, most of the charts you see talking about Half Lives, are really "Active" Lifes....I have 3 Charts saved on my CPU, and there is even a Thread going as we speak, that says "half" life, but they're really "active" lifes. These are commonly confused.
    Pheedno has the half life thing down...maybe he'll post up...I think he (or someone) did once, but I can't find it right now.
    But like I said, I believe Enanthate is about 4.5 or so, with Cyp being about 4-6 hours longer (Which MANY Charts say shorter, but they're wrong) Prop is like 27 hours, and Tren is a bit shorter.
    I've been up for at least 60 seconds, so double check anything I'm saying right now!

    The drug mentioned is Methyl-Test (Methyl-testosterone )

    Not Methyl-1-Test (Big Difference)

    Either way..The info above is incorrect as Methyl-testosterone (Oreton) is noted to have peak activity at 2 hours post-ingestion..and a metabolic half-life of mere hours
