My vial is close to three months so perhaps that is the issue. In any case the initial effect was encouraging enough to try another vial.
May I ask if you had any issue with side effects? I experience a little flushing and a hint of nausea shortly after injection. Both are mild and transitory. I do experience a little soreness/fatigue which I do not like but it is not a deal breaker. I still have not figured out timing. In my case it reaches peak effectiveness anywhere from 4-8 hours after administration. Would love to hear others experience.
