My thoughts on the difference between different brands of gh is the amount of mannitol used as an excipient, given the gh is of a high purity. Mannitol is a diuretic. Serostim has no mannitol and is fda approved for weight gain in people with HIV. A 12 mg genotropin pen has 46 mg mannitol and is used for growth in children where water retention would be seen as a negative side effect. So the serostim should give more fullness and the genotropin should give a dryer look. With generics the purity may be similar or meet pharma standards, but only the manufacturer knows how much mannitol is used. So it would be more of a gamble for some coaches to recommend generic gh going into a show unless the client is using the same batch of gh. And the coach dials the dose in based on the look.Okay, so I watched the GH part at about halfway in. He's saying most samples sent in are actually way better than what is required to claim a pharmaceutical standard. But the question is again, if all is "pharma," why the persistent debate over China GH vs well established brands like Genotropin. I guess what I wanted to hear is that in this guys view is the China growth still deficient in some way, e.g. is Geno better? I know this has been debated ad nauseum but just the other day that 20.000ng test level guys, Chase something, raved about how much better Serostim was vs generic, says you can tell big positive changes within a week when switching to Sero, said he used generic for 8 years and it wasn't doing much at all. Thoughts (again)?
