be patient, i have personally seen great results with intermittent use of igf over the past couple years. many are dissapointed when they dont make huge gains of it right out the gate. that is not how it works. now mgf i do not think it has been out long enough for anyone to really say, i personally used it once and did not like it, apparently i did not take enough but at the doseage recommended wouldnt want to put out the money to see if it is any good.
