There's nothing that says you couldn't stack the two products, since androsol is like mag-10 but without the A1E component. With that said, if you were planning on stacking the two products, I would only use mag-10 once per day and use androsol to keep the blood levels of 4-AD more constant. You would probably want to cut the dosage of androsol down to 70 sprays a day if you were going to do this, essentially using half dosage of both products each day. And if you did that, use the majority of androsol opposite the time you use mag (i.e. if you were to use mag in the morning then spray at night).
Honestly if it were me I would just go ahead and use the androsol in its entirety before starting your mag cycle. (and if it were me I would also find a source of finaplix to supercharge the mixture. gotta love finasol) But I would just use the products separately from one another, because they are essentially the same thing, except mag gives you the added benefit of the A1E.
