May as well finish what I started...

Perhaps the scariest thing about being Type 4 is that not only will you be subjected to consciously feeling your impending doom flowing in your veins, but the nature of the experiment is simply harrowing.

Your own puberty has been inhibited. Through a cocktail of complex **** and treatment, you will never experience the slow development of your body as everyone else your age on this planet will. Instead, your DNA has been spliced and recoded using the genes of a prize stud stallion. The equine was chosen for its vitality and excellent health, meaning that theoretically, you should not suffer as much if the genefusion occurs successfully.

You have been told that instead, your 'puberty' has been altogether replaced by a stage of total body reformation, reconstruction and mutation. The smart-enzymes within your cells inhibit the activation of the equine genes in your DNA until the scientists give the cue. When the gene has eventually found itself in enough of your cells, the transformation will begin in an "accelerated form of puberty", if you can recall correctly.

Until then... Well, all you can do is wait.
