They have really been pushing the 1ml vials, because they claim the 10ml are a multiuse vial w/ risk of contamination, but I wave the BS flag.
Most Drs. offices have 10ml vials of 100mg/ml and 200mg/ml vials for horomone treatment ( the 100mg/ml is used for females) and I know the 10ml vials of 100mg/ml test sits for more than a month occasionally.
Also, unless you're scripted 200mg/week, the 1ml vial by definition become a multiuse vial.
