Hey brohter, good questions. A good way to see what effects you get from the GH releasing peptdes, would be to get some labs done while on them. Maybe stop your GH for awhile. Then do labs to see your GH and igf levels. For this experiment, I would also stop the IGF, MGF and anything else that could effect the reading. That would be the only way to really know what you are getting>. Then you can ask yoursel if it is worth the cost.At your age, you should get some decent results using 2-3iu gh. And if you are getting real IGF, more power to you. As for the MGF, I have never seen anyone get ANY effect from it. I have heard that you are supposed to use it with IGF to get the full effect. I dont know though I have seen people use it both ways.
