I used spray at first but remain unconvinced by it's efficacy. I also made up some PM cream but did not persist I did however use wild yam cream and felt that it helped; then the source dried up.
You should, within a few weeks, be aware of your chest becoming fattier. This should be followed by your nipples becoming erect and, then beginning to point slightly outwards. Next you will be aware of lumps [knots] behind the nipples and, then, the tenderness kicks in. This process took me about 4 months. Within another month I was aware that I had no sense of maleness left, mentaly.
I say this, because, if it is not happening for you, you probably need to up your dose. Once the knots appear and the tenderness kicks in, you are in a better position to judge; any reduction in the size of the knots , or in tenderness and you need to up the dose, even if it if just long enough for the sensations to return. I started on 2000mg daily, with the occaisional ramp up to 3000, or even 4000, but now have settled into 3000. At 2000, the knots had gone, along with the tenderness and growth had besome very slow. Now the knots and tenderness are back and things are back on track. You will find that there is a wide difference in the cup sizes of bras and, in the last week I am filling out, the biggest of my bras, very nicely; it gives a girl such a boost!
