I'm doing a minimum dosage for test (250 mg a week) for trt, I have felt a slight change on my libido but not how I wanted to, is ok to have a little extra push with viaggra, or that can cause me any health complications?
It is perfectly safe to use viagra in combination with a steroid cycle.
Just make sure not to use viagra daily as your body can become dependent on it and eventually you won't be able to get an erection without it. I would only use erectile drugs like Viagra or Cialis 2-3 days per week.
Just a tip, you can legally order viagra as a research chemical liquid from ag-guys.com. It'll be the exact same drug as brand name viagra, just much cheaper.
