Cialis (tadalafil) and Trimix?

I asked my provider about doing the daily dose for blood flow and using the Trinidad for erections. They said they don’t generally do that unless the trimix doesn’t work. I am thinking about passing trimix and starting cialis. I got introduced to trimix 7 years after surgery and only occasionally having a softish erection. Trimix works great, but thinking I jumped a step

I have had a reaction to both Cialis and Viagra consisting of large dark (purple) round blotches about 2" diameter on my upper body. These eventually go away after 2-4 weeks. I'm concerned that I may get a reaction from Trimix also. Has anyone had any similar experiences ?

5 and 1/2 mos post surgery 2.5 mg Cialis daily for rehab and Trimix 10-15 uts PRN for intercourse. Natural erectile function returning

Had similar reaction to Viagra. Not so with Cialis. Trimix not same class as Viagra. I use Trimix with fantastic results

Do not assume same will be with Trimix. It was not for me and this product is a game changer.
