Half-life estimate, not bloodwork or dosing advice. Disclaimer.
Four testosterone esters in one vial (30 mg propionate, 60 mg phenylpropionate, 60 mg isocaproate, 100 mg decanoate). The plotter expands one dose into those four curves.
The default row models 250 mg as an intramuscular dose, weekly, for 12 weeks.
Also called Sustanon 250, Sust.
| Half-life | 7.5d |
|---|---|
| Time to peak | 3d |
| Parent hormone | 70% |
| Default dose | 250 mg |
| Default frequency | Weekly |
| Default duration | 12 weeks |
On that default row the model counts 12 doses. Steady state is about day 37.5. Washout runs to about day 40.5. In the last interval the peak is 223 mg and the trough is 124 mg, a swing of 44%.
About 70% of each milligram is parent hormone, so 100 mg of Sustanon 250 leaves about 70.0 mg of Testosterone.
A half-life of 7.5d means a dose is still present at the next one, so the line climbs and then levels off.
Test P has a half-life of 0.8d against 7.5d on this page. Parent hormone is 80% there against 70% here.
Sustanon 250 weekly plots 250 mg weekly for 12 weeks. It is an illustration already in the app, not a protocol to follow.
