So I ordered some mc igf Saturday. Stuff Got here monday, fastest shipping ever btw! Decided to see what everyone was talking about today, did a simple 20 mcg in each bicep and did arms. Driving to the gym with this stuff alone gave me a nasty pump and in the gym I literally felt like my skin was going to rip open even now 2 hrs later if I move my arms they are still swollen to the gills! This stuff is incredible!! Can't want to continue this! Thank you MC IGF for the most painfully amazing pumps ever!
