Phantasy, if you buy it from Alpha Dream at 1mg/mL, that comes already fixed (time-extended) with DPG, and will come out at about 50mcg per drop. You can apply it straight from the dropper bottle and cover with fragrance (or not, really, Estratetraenol smells fine.)

Soon I'll put together a post with instructions on creating your own spray mixes.

Thanks, I've written that down for when I get some.

It will be good to read any guide you write on mixing. However, I've decided not to even give that a go until I first have a handle on what I'm doing and, understanding and recognising reactions in others and myself.
