For no reason, just saying:
If you want to make medication yourself and/or suggest that other people not already in the business do so, you need to a) figure out how to prove *for each dose* that whatever substance is produced doesn't have anything else bad in it, and b) will be effective and at the expected dosage, and c) what degree of certainty you've done and and b to. You should probably also prove d) what the expected shelf life is, but a, b, and c are the absolute minimum. They are also significantly harder than making a substance.
If you have no plans for a, b, and c, you're not doing anything that should be described as making medication.
