Length of Time TriMix Erection is Effective? How long does it keep you hard?

[brian188]

I’ve been injecting now for over a year and have determined that with a good injection I remain hard on average for 1:45 minutes. I base this on my erection remaining firm until I notice the first signs of losing my firmness and not to the point where I am completely flaccid.

I gauge the time when I have nothing left but “a chubby” to be around 2:30 hours.

What do you other men see as far as how long TriMix works to keep you hard? Time to lose firmness? Time to nothing more than a “chubby”?

I stay hard for about 1-2 hours depending on how much i use softens to a chubby for about 2 hous or so been using trimix for 3 years use 15-20 units depending on how long i want to stay hard use 30-1-25 strength

I am using 10 units, the same as when I started two years. 100 injections, missed twice. The first time (two years ago) got nothing. The last time I missed, after 5 minutes of nothing I inject a second time. Thankfully that's only happened once in over 100 injections.

I almost always inject after midnight.
Hard for 1-2 hours.
Since the injection is almost always after midnight. I go to sleep after sex. And will awake 2-4 hours after injection.
I will then get up to make sure it goes down, then go back to bed.
It's usually not fully flaccid until after 4 hours.

I usually always stay very firm for well over an hour, sometimes two hours. The total duration until down to just a chubby is on average two to three hours for me.
