ok just doing a search on here i read that 1g of powder displaces 1ml of liquid,and that everclear can easily be used as my solvent.so if i wanted to make 50ml @ 20mg/ml i would use 1g powder and 49ml of ec.is this right.if i wanted to make it 40mg/ml would i just go 2g powder and 48ml of ec?

Close enough yea. Nolvadex doses should be multiplied by a factor of 1.5 when doing your own conversions. 3mg Nolvadex = 2mg tamox citrate

I think you mean: 2mg of Nolvadex = 3mg of tamoxifen Citrate.
