The simplest protocol you can do is taking HGH and Lantus before bed.
Start at 4iu HGH, 10iu Lantus daily.
On Lantus website there's a calc, i would stick to that ad max dose.
Later on you can add 5iu Humalog postwo after your meal.
@Type-IIx for sure has a more refined protocol, but using insulin like that, gave me best results.
I would do also more research about Metformin, which it's not a walk in the park....
Can give Vit B deficiency, you need to add something to help mythocondria (NADH/CoQ10), it can raise acidic load
