I am currently on test cyp. Injection twice a week at 50mg. (Wednesday and Sunday injections 100 total a weekI have resistant hypertension. 10 mg or amlodapine (sp?) daily. I was also prescribed 50 mg of viagra. (Few years now and well before starting test). Thinking about getting on 5 mg of cialis daily in the morning. I have read taking both is dangerous. However I have also read where people have taken the daily low dose of cialis (5mg) and then knowing if sex is going to happen also take a low dose of viagra before the sexual encounter. Maybe 25 mg or less. Has anyone done this? Only reason saying I am 50 years old and sometimes I would take 50/75/100 mg of Viagra before the deed. My body has got use to 50mg.
