I agree with Barb. Never use anything that isn't approved by the country's government or you run the risk of doing more harm than good.
Sounds like you have quite a "cocktail" going there. I've never heard of somatropin or clenbuterol so I just did a real quick search. From what I read, clenbuterol is used to treat breathing problems in horses and is not approved for human consumption - at least in the U.S. It sounds like it could be very dangerous.
It's much safer to lose 1-2 pounds/week by implementing a reasonable diet and exercise program. We'd be glad to help with that if you are interested, otherwise, you might try Weight Loss Alternatives - someone there might know more about it.
Good luck.
