Nolva is not an AI, it is a serm. Why would you need an AI? Epistane doesn't aromatize.
Also, you do not wait 2 weeks after the cycle ends with "AAS"... how long you wait depends on the half life and active life of the compound. For example...testosterone enanthate, 2 weeks is about right. For testosterone propionate about 3 days. For testosterone suspension or orals, you would start the next day after the cycle.
