Bill,
Let’s say, hypothetically, someone was to make an injectable preperation from the hormone powder that accidentally precipitated out of the solvent of this product. Not that I or anyone would or should think of doing this.
Just for fun, how would the dosing recommendations change and what injection locations would be ideal? Thanks for pretenting with me.[/quote]
It would make for a problematic injectable because the oil solubility – though it hasn’t been tested but just based on the alcohol solubility, the melting point, and comparison with how these factors relate to oil solubility with other similar compounds – is almost undoubtedly much less than would be desired.
The half-life of the injectable would undoubtedly be short, being an acetate: so daily injection would be best.
While one would want to work up to it in the event side effects (probably just being excessively stimulatory) were problematic, I would guess that somewhere around 150-200 mg/day would probably be about right.
That might very well, with the poor oil solubility, be something like 15 or 20 mL per day of injectable required. That’s obviously not reasonably feasible.
Probably the only practical way would be as a suspension, but I don’t know how to make a good one. (Simply being a suspension isn’t enough to be a good product: particle size and particle size distribution are important.)
It doesn’t seem worth the trouble if the bioavailability improvement would be only say 2 to 1 which is all it may be.
Locations wouldn’t be important, I don’t think, as the injection sites have to be muscle, and blood flow is such that blood returns to the heart first from muscle before getting to any fat (except intramuscular fat, but that’s not a major cosmetic issue usually.)
