why is 10 weeks ideal for test E?

[gained75]

i know most recommend 10 weeks for a 500mg/week test cycle but can anyone explain why? why not 4 or 8 weeks? always wondered lol thanks

[THE_DOME]

because it takes 4-8 weeks to kick in,

[gained75]

yea but wouldnt it still work for those weeks after it kicked in? like if it takes 4 weeks to kick in, and you stop after 4 weeks, wouldnt you have 4 weeks after you stopped injects?

HALF-LIFE BASICS

Each compound includes an ester that, along with other factors, controls the release of the hormone into the system. The rate of release differs by ester and is defined in terms of half-life. The average half-lives of esters are:

ESTER HALF LIFE (days)
Formate 1.5
Acetate 3
Propionate 4.5
Butyrate 6
Valerate 7.5
Hexanoate 9
Caproate 9
Isocaproate 9
Heptanoate 10.5
Enanthate 10.5
Octanoate 12
Cypionate 12
Nonanoate 13.5
Decanoate 15
Undecanoate 16.5

The half-life is the length of time (in days) to release half of the hormone into the system. For example, if 500 mgs of Testosterone Cypionate is administered, in 12 days, on average, 250 mgs of testosterone has been released into the system and 250 mgs of testosterone remains attached to the ester. In another 12 days, an additional 125 mgs (half of the remaining 250 mgs) has been released into the system for a total of 375 mgs released and 125 mgs still attached to the ester. The key detail is that different esters release the hormone into the system at different rates.
