In the attached picture it seems that max serum Test release in milligrams occurs immediately after injection. This doesn’t seem right and has implications on the build up and decay of serum levels.
The example graph shows 4, once weekly Enanthate injections of 500mg
Maybe I’m missing something, I’m interested what others thoughts are on this?
Thanks
Serum levels are increased significantly within as little as 6 hours from some studies but usual peak is about 24 hours post injection from what I’ve read.
Just seemed odd not to factor it in. I guess it’s maybe negligible in the grand scheme of things
You can look at a plot of a single 200mg injection of test e and see that in the first 24 hours your levels peak, then lower over the course of the next 3-7 days. The plotter does an ok job of showing this, but i would not take those figures as gospel because they don’T account for a lot of personal variables. I’d just use it as a basic guide to understand how the testosterone is entering your system
Nice thread!
Example:

I have a bunch of stuff over at ExcelMale on this and estimation of Tmax (time for Cmax). For cypionate and based on individual range for absorption and elimination rate constants, Tmax works out to approx. 8 to 36 hours.
I promised to be good and not link to ExcelMale any more.
Just more math and next level of complexity. Too much for an internet steroid plotter 
.
Any change you plan on sharing that excel sheet? Or sharing the formulas to allow others to build their own? Steroid plotter is nice but I’m an engineering nerd that like a greater level of info an granularity
Do you have any good sources listing values for these? Likely derived empirically.
Nice work by @anon18050987. What happened to him anyway?
Table 2:
Example of use:
Input for spreadsheet:
Examples use apparent absorption half life of 8 hr and elimination half life ~4.5 d for test cyp.
The original crappy elimination only models with instantaneous absorption finally got replaced with the refined absorption + elimination over in the What is TRT thread further down.
Nice reference!
Permanent suspension. 
If I wasn’t so paranoid with metadata I would just upload the Excel file. Let me look at that.
Excellent! Will take a proper look look when I get a chance. Hopefully get some sensible numbers out!
Neat TT vs dose tool, will aim to contribute some data to that thread shortly. At a glance I seem to be an under responder😢
