this is my 1st time trying a slin only cycle. ive done 5 cycles in the past... i'm 5'11" 215lbs. tell me if this slin protocol is safe:

1. workout
2. inject HUMALOG (start with 1 unit, increase by 1 per day until a max of 12 units per day)
3. drink 10xUI grams of glucose, protein, creatine in a shake as soon as i finish the injection
4. 1 hour post injection, eat beef and rice
5. 2 hours post injection, eat chicken and pasta
6. stay cautious for the next 2 hours

QUESTIONS:

is this safe?

how good are gains kept?

how long should I wait between cycles to avoid insulin insensitivity?

if I do too many slin cycles, will i become diabetic?
