Hi Dan
When I was using Trimix injections, I got fully hard within 10 mins, and stayed hard a good 2 hours, even after cumming.
I had a nice chubby for about 2 hours after the first 2 hours.
After about 8 years and increasing the dosage, I would only get hard for a few minutes.
When I started on Trimix, my uro told me that I would eventually need an implant.
Started with Viagra at age 40. Worked good for about 12 years.
Tried Trimix injections, worked great for about 8 years
Now Trimix no longer works.
I got implant on Oct 26th 2022.

I get hard pretty quickly: 5'ish minutes. Lately, it's been random for when it goes soft. Sometimes just ½ hour, sometimes 3 hours. Often, I'll go soft in 45 minutes then pop back up ½ hour later.
Born 1954. Diabetes, hypertension, atherosclerosis, MI. Sildenafil became ineffective. Tri-Mix 30/3/20 Pap/Phen/PGE1 godsend so far. Daily Cialis. Tried LiESWT 13 times, Botox, PT141, Eroxon, QST, DUS, Vertica, Ferticare, cabergoline, psycho+hypnotherapy.
