I get a great feeling of well-being from IGF2. I have tried Powerfull on 3 different occasions and each time it has caused a lethargic feeling that made me stop. I have read that they were similar supps. Why does IGF2 work well and Powerfull cause me a problem? What is the different ingredient?
Second IGF2 question - will it make sense to take it when I'm on a cycle of 4AD transdermal?
