Cataceos. About dilution of medicines. Here I have hydrocortisone powder to dilute in water for injection. If I use bacteriostatic water to dilute the powder, could I apply subq and store the rest in the refrigerator? I have to take 30 mg a day of hydrocortisone. This topic is about progesterone, but I have this question or I can open a new topic. ThanksI have PMs ongoing with another member on this subject, so I'll just quote myself from them. The conversation is referring to ampules from AllDayChemist, but I'd do something similar with vials obtained domestically, except no need for filter needles.
"In more detail: I use a filter needle and luer-lock syringe to withdraw the progesterone from an opened ampule. I change to a regular needle and inject the progesterone into a new sterile vial. To the vial I add benzyl alcohol and grape seed oil to reduce the concentration from 100 mg/mL to 20 mg/mL. For administration I use 0.3 cc, 31 gauge, 5/16" insulin syringes."
...
"I bought the 2 mL ampules, which per mL are said to contain 100 mg progesterone, 200 mg benzyl alcohol, and ethyl oleate to complete the milliliter. If the contents of one ampule were transferred to a 10 mL sterile vial then you would add 1.54 mL of benzyl alcohol and 6.46 mL of grape seed oil to the vial to reduce the concentration to 20 mg/mL progesterone (10 mL total product with 200 mg progesterone and 2,000 mg benzyl alcohol). I don't know if the benzyl alcohol concentration really needs to be as high as in the original product. It's good practice to divide the results into a few vials so that you're not using any one vial for too long of a period, e.g. more than a couple months or so."
I mentioned possible suppliers of the ancillaries: Med Lab Supply, Tex Lab Supply
For uniformity you could buy and use ethyl oleate as the diluent. This is what I did originally. But then I decided I'd rather not be taking more EO than necessary, so I switched to grape seed oil, which seems to work just as well.
