Read this before you rely on anything the plotter shows you.
This is not medical advice
CyclePlotter is a calculator. It draws a mathematical curve from a published half-life figure and the numbers you type in. It does not know your medical history, your bloodwork or your circumstances, and nothing it displays should be read as a recommendation to take anything.
It does not recommend doses
The plotter has no default protocol, no suggested amounts and no opinion on what you enter. Every value on the chart comes from input you provided. A curve that looks even is not evidence that a schedule is appropriate or safe.
The model is an approximation
Half-life and peak concentration values are population averages drawn from published literature and vary between individuals, injection sites and preparations. The curve is an estimate of serum concentration, not a measurement of yours, and some compounds have no published peak at all. Only laboratory testing can tell you what is actually in your serum.
Anabolic steroids carry real risk
Use of anabolic androgenic steroids is associated with cardiovascular, hepatic, endocrine and psychiatric harm. In many countries possession or supply without a prescription is a criminal offence. If you are using or considering using these compounds, speak to a doctor and get regular bloodwork. A harm reduction service in your country can usually advise without involving law enforcement.
No warranty
This tool is provided as is, without any warranty of accuracy, completeness or fitness for a particular purpose. Values in the compound database may contain errors. You are responsible for anything you do with the output.
