[QUOTE="Cataceous, post: 193824, member: 38109"] First, the testosterone content of an ester such as T cypionate is only 70%. So your 49 mg T is contained in 49 / 0.7 = 70 mg T cypionate. Second, normal men have a diurnal variation in serum testosterone that peaks in the morning. These levels are what's typically measured, and are what guys on TRT usually aim for. But later in the day normal men see levels drop by 40% or so, whereas those on testosterone cypionate may see fairly constant levels over each day. A rough estimate is that this increases the testosterone requirement by 25%. So now you're up over 90 mg T cypionate, which is getting pretty close to the nominal 100 mg/week dose. Furthermore, if a guy is injecting only weekly then he must go higher still to make his troughs match the peaks of normal men. The bottom line is that if you can dose your testosterone such that your serum levels approximate what's seen naturally then you'll find that the total amount of testosterone needed is comparable to what normal men produce. I do this by injecting a blend of testosterone enanthate and testosterone propionate daily. The total testosterone dose is only 4.4 mg per day, yet it's providing quite normal peak testosterone in the 600s ng/dL. [/QUOTE]
