If you put in your cycle it will tell you the daily amount in your system.
For an example
My next cycle looks like this
1 625mgCyp e3d + 400mg eq e3d
2-15 312mgCyp e3d
2-14 200mgEQ e3d
this keeps my daily amount of test near 100mg and eq near 70mg rather than having them jump from 200mg down to 50mg
its the same amount of gear in the same times but better planned for consistency.
I dont know how much of a difference it makes but I like to think im doing it the best way possible.
