Hi,
I have a question on how i can dose a 1g of alprostadil raw powder to be homebrewed or in other words dry mixed and give a concentration of 10mcg. This is going to be injected. I did some research and it seems the pharmaceutical drug 20mcg or 40mcg product contains:

172 mg of lactose, 47 mcg of sodium citrate and 8.4 mg of benzyl alcohol. Are the mentioned ingredients important? Or is it possible to use BAC water directly with another medium? The medium ingrediant i believe is to distribute that 1g into a big volume. Similar to making dbol capsules using protein powder

Im trying to make a dry mix that i can dilute when i need to. 10mcg per 2ml empty vial

Let me know what you suggest
