Once a day the HL is long as hell (35hrs? dont quote me) Taper up as sides dictate, 120mcgs is a pretty solid high side. I'd start slow at 20mcg for day 1 and 2, then go up. Take Taurine or you WILL cramp. Jaw cramps are the worst. 14 on 14 off is standard, diphenhydramine or ketofien will help clean receptors off making longer cycles possible.
If you get up to 100+ mcgs a day some people split doses, a popular one is 1st thing in the AM and then right before bed. As long as you get to sleep before it takes full effect you can dodge a lot of sides, ie shaking.
Be careful. Listen to your body.
