Help a guy to fine-tune his bimix dose

[FDV70]

I finally got bimix that works, I was getting a premix product and not a lyophilized product. It was probably inert from lack of refrigeration.
I did 4 units of a 30mg Papaverine, 1mg Phentolamine per 1ml product.
I got a chub for about 40 minutes. My "antidote" vial is on backorder so I want to get the next dose right and not overdo it...

My question now becomes if 4mg produced a weak effect, do I double it to 8 units? Go right to 10 units? Will I get fully erect and last twice as long or 80 minutes, or is it possible 40 minutes is more likely? Even if it's guesswork, it's not likely that if 4 units is 40 minutes, 10 units would not be anything crazy like 4 hours, right?

Thanks all

If it matters I have no diabetes or comorbidities, I am 54, I can get normal erections, I just cannot sustain them. I am larger than average in length and girth if that is relevant.

Bi-Mix is much more forgiving than Tri-Mix with dosing too high, because the medications have a shorter duration of action than the alprostadil in Tri-Mix. I think you would be fine to increase to 8-10 units without any risk of a 4+ hr erection.
