Since i have no ambition to distribute my home brews and it is strictly for personal use, i wanted to ask about the viability of using 30-60 or even 100 ml pre sterilized vials for weekly use. i found some pre sterilized with ptfe coated stoppers. Is there a viability issue with doing it this way? with a 60 ML vial i can make 50 ML batches at a time as needed and just use it that way. i do shoot IM with a 25g pin, but generally i will draw with the same needle i pin myself with and have not had any issues. but how well will the stopper hold up to 10-20 draws with a 25g needle? is it better to go 20-30 ml vials to reduce the over all penetrations into the vial?
