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.

Thanks so much FunkOdyssey! 8 units was good for 2 hours. Much appreciated. [The only curious thing was that it took 10 minutes to 'hit' even with massaging it around, but no matter.]

That is actually a good thing and more natural since you can start playing with your partner and they will feel more "involved" with your emerging erection. Walking out of the bathroom with an erection without foreplay shocks most sex partners. Embrace the process.
