Half-life estimate, not bloodwork or dosing advice. Disclaimer.
Masteron enanthate. Longer ester of the same parent as Mast P.
The default row models 200 mg as an intramuscular dose, twice a week (e3.5d), for 12 weeks.
Also called Drostanolone enanthate, Masteron, Masteron E, Mast.
| Half-life | 4.5d |
|---|---|
| Time to peak | 2d |
| Parent hormone | 70% |
| Default dose | 200 mg |
| Default frequency | Twice a week (E3.5D) |
| Default duration | 12 weeks |
On that default row the model counts 24 doses. Steady state is about day 22.5. Washout runs to about day 24.5. In the last interval the peak is 336 mg and the trough is 267 mg, a swing of 21%.
About 70% of each milligram is parent hormone, so 100 mg of Drostanolone enanthate leaves about 70.0 mg of Drostanolone.
A half-life of 4.5d means a dose is still present at the next one, so the line climbs and then levels off.
Mast P has a half-life of 0.8d against 4.5d on this page. Parent hormone is 80% there against 70% here.
Cut — Test 200 + Mast E 400 plots 200 mg twice a week (e3.5d) for 12 weeks. It is an illustration already in the app, not a protocol to follow.
Ester fraction ~0.70; enanthate half-life ~4.5 d from the community PK set. How the model works.
