That´s what i think , but here in brazil somatomedin tests are not really trustable.i found out a research who says thats sometimes the people does not increase the levels and still have good effects . I do not know what to do know. Tell me what you think. I fell so bad about that. I spend a lot of money in my cycle.i buy for a very safe place with a doctor prescripcion.sould i repeat the test in another lab??? Thanks a lot. I talked to my doctor and he says that i lost 5 cm of abdominal fat so it has been effect. I was expecting minimum 400 as you said.tell me your opinion please.
