unlike T it takes 10 days for your body to stabilize on AI. So start with .25mg 1X/week. Keep track of sleep, energy, morning erections, libido, ... I use a 123 scale (bad, good, Great!!!) track all your symptoms daily. After 2 weeks, increase teh AZ to 2x /week and so on and so forth. At some point you'll hit diminishing returns. Aches, pains, lower libido, lower erections. so you can reduce it to a known level once you get there.
