The horse study was done with water testo suspension but no specification of concentration or ingredients. I was quite shocked of their graph that it was still detectable after 30 days in horses.

I would go for water testo suspension with the highest available concentration. That should decrease the volume of the injected water and should decrease the absorption time (a drop of smaller volume will have a higher ratio of contact surface to volume). I am not sure if using an oil suspension will speed up the absorption. The injectable esters are in oil and they do not absorb fast but the injectable volume with them is much larger and it is not clear what effect is played by the oil - does it speed up or slow down absorption.
