RE: Transfered Juice
The gear will not be sterile now by any means, i personally would not use it as there is allways the risk of infection.
Infact, when you withdraw from a new 10ML multi vial the remaining gear is actually not sterile as air will have entered the vial, so risk is allways present i guess with a multi vial anywayz.
The concern for me would be the last drops of oil left in the first vial you had on the cycle, this will have had plenty of time to cultivate bacteria..
it your call bro, but an abcess can be very painful and not very good at all for your bodybuilding,
