I dilute with bacteriostatic water. 2 ml per 10 mg. But the injections are very painful. And for a week there is inflammation at the injection site. intramuscular injection is better.
Not sure what the white cap has anything tondo with it, but my mots-c injections stings for a few minutes after injection. It goes away and there’s no red marks afterward. I take 2.5mg 2xweek in either inner thigh or tummy area.
