Trimix, tolerance so quickly?

[Inject77]

Hello, I'm new here, but I've been reading posts for about a year. I developed ED due to cycling. I injured the pudendal nerve and lost almost all subtle sensitivity in the glans, which left me unable to have intercourse using PDE5 pills, so I ended up having to use Trimix. The sensitivity is enough to achieve orgasm, but not enough to maintain an erection in certain positions where vaginal friction is lower.

Since I initially had no vascular issues detected by Doppler, I only needed 5 units of Trimix 10-1-30 (PGE, Fent, Papa) to achieve a good erection lasting one hour. Now, after a year of use and approximately 100 injections, I’m having to use 18 to 20 units to get a firm erection. If I use 10 units, the erection can last up to 2 hours, but the rigidity is poor. With 20 units, I get a 9/10 erection that lasts 3 hours.

For those of you who have been using it longer — did you also have to triple the dose in such a short time?
