To answer your question, Depending on what AAS's your on, if they are likely to aromatize then take the L-Dex at up to 1cc ed (most common is .5cc e/d) the nolva can be taken at 10mg day as a preventative measure but if you get signs of Gyno take it at up to 2cc's (40mg) per day till the itchyness/tenderness disappears.
In you original message there will be a little box to edit your post. Please do this. It doesn't really matter where you got your liquids from, they all pretty much work the same.

Thanks
