Perhaps it was Milos who was whispering in Victor's ear haha. Milos was involved with some of these guys through Victor iirc.
If I recall correctly some of the BALCO athletes got 3iu, and I think post-workout. However, imo it would be very hard to measure if this "did" anything, even after a long time. You can go by subjective feeling of course but otherwise how would you know it's working or helping your case?
There are some old Russian writeups on insulin use in athletics, and iirc they sometimes added like a single IU of insulin to a regimen. I think it was to supplement some perceived "deficiency" or something. But again, kind of hard to know if this is actually doing anything measurable, you know what I mean?
I support the idea regardless lol.
