Ian,
There are numerous trimix threads to browse .. you can use the search function.
A few quick thoughts -- others will have more and better points:
- You will need a script for trimix and a compounding pharmacy (not a regular pharmacy) to fill it.
- The first "test" injection with trimix should be in the dr's office. Bring your wife!
- Be clear with the dr on how to adjust dosage. Most dr's insist they be consulted before any dosage increases on your own.
- Make sure you discuss with your dr what to do in the case of a prolonged erection .. when to head to the ER, etc.
- Trimix needs to be kept refrigerated or frozen .. get instructions from the pharmacy.
And, have fun!!!
