@Terrificli -- You are sort of missing something when it comes to human growth hormone. If you are dealing with true growth hormone (which is a drug) then you are talking about something that can only be obtained with a prescription in the United States. It is also worth mentioning that a lot of organized sports ban the use of the growth hormone drug.
But, when we are talking about human growth hormone spray and other things that are freely available without a prescription we are not talking about something that has the actual growth hormone drug. No, we are talking about primarily dietary supplements with a bunch of amino acids and other things.
