I've been type 1 for 18 years now. 4-7 shots per day. Rapid and long and acting insulin.
One misconception people have is that insulin acts like AAS where more is 'better.' Not the case.
Another complication is that when 'healthy' people take insulin, they effectively have 2 sources of insulin acting: their own production and what they inject. So readings from a glucometer will not be all that useful.
Agreed that death is unlikely. Usually it involves a high level of negligence: overdosing then falling asleep, getting drop down drunk, driving a car, etc.
IMO not worth it unless competing at a high level.
