[url][/url]Tried both Trimix and Quadmix (150/20/200/2), up to 50 units, with mediocre results: enlargement, but no firmness. What made a bit of difference were testosterone injections, after I started those penetration became possible, though with some effort.
Cock ring doesn't help.

I'm 67, had ED for the last 7 years, using Quadmix 150/20/200/2, up to 50 units. None of oral meds worked for me. Initially Quadmix didn't help much either: it produced enlargement, but not enough firmness. What made some difference was testosterone injections. With those penetration became possible...
