like how would you even mix up a 10mg vial. How much bac water then doing it with your slin pen. Do they come in a small vial or is it a big vial?A vial is good up to 2 months(per the manufacturer) at room temperature or even protected from light. I would anticipate it be good longer if its kept in the fridge and in good conditions.
2mg even at a starter dose would be a 1.5month supply at the start.
1st month you utilize 1mg. 2nd is 2mg.
3rd month is 4mg. 4th is 8mg.
Now for resale purposes... 2mg might be a good idea to sell to Karen. Karen might think they are getting a deal and can trial it out for their friends.
