Ever since starting school and working night shift and weekends ive lost alot of sleep. Im really tired on mondays. Mondays are about a 26 hour day for me continuaslly staying awake. I manage with the use of clen only on mondays to get me through the day. Sometimes thats still not enough. But when I started IGF, not only did I notice size gains and fat loss oh lets not forget the pump, the endurance is where im going with this. It helps me stay more alert, accomplish more at a more energetic level than I normally would have. Thats with applying 60 mcg in the morning after getting off work before school. Thats my personal encounter with MC IGF. It works in many ways.
