Drug testing before and after games hasn't changed the number of athletes who now secretively use Growth Hormones that are tough to detect through ordinary methods like urine samples.

Sorry* Is this a better thesis ?

Still too much.

End the sentence after hormones.

Honestly ! What would you advise me to stick to at this point . Because I have attempted writing atleast 5 thesis statements and I am dreaded !!

If I go about the statement I put above I do not have enough sources to defend my argument either .

Please do advise

or...

Various approaches to prevent steroids in sports have not bin successful because athletes are now using hard to detect growth hormones which calls for a analysis of better approaches

I hope you are patient with me .

Sure -- I'm patient. :-)

I suggest you stick with this:

Various approaches to prevent steroids in sports have not been successful because athletes are now using hard-to-detect growth hormones.

I hope I do well on this paper because writing this thesis was the hardest.

Thanks for all your help I really do appreciate it !!

You're very welcome. I'm sure you'll do well on this paper.
