A 10-12 week cycle is normal. There is no need for PCT, just taper off the dosage.
Anavar - start at 5mg/day. Try to split the dosage up AM/PM. After a few weeks, after you see how you react to the drug, you can up the dose to 10mg. Run at 10mg for a couple weeks, access your tolerance, and then bump to 15mg/day if you don't have any masculine sides. I personally think you will be happy with 10mg/day. Towards that last couple of weeks, drop your dosage back down to 5mg/day.
Clen - Run 2 weeks on/off through-out the var usage. I don't think you will need any more than 60mcg/day.
T3 - I don't think you will need this. But if you decide to use.. start with don't go above 75mcg, and run for 6-8 weeks.
