It seems impossible to find TD formestane, but the oral version is readily available. I have Formestane from Fusion Supplements and the only filler is corn starch. As formestane is insoluble in water or ethanol, I'm considering 2 options:
- Ethyl acetate: so far it seems to work, later I will report the yield. I don't know the solubility in ethyl acetate, but around 100 ml could be fine for extracting a whole bottle (4.5 grams). The only issue is evaporating all that amount later. EDIT: yield around just 50% but this was a test with a little amount a no vacuum filtration, which is mandatory.
- DMSO: formestane is soluble in DMSO (57 mg/ml), but DMSO has an high boiling point. Perhaps adding water will "break" the solution and the formestane precipitates. I have to test this. EDIT: Yes, it works and seems to be the easier way.
