Congrats! Not sure if it makes much difference, but these are the general rules I follow with the gel:
Put it on shortly after showering, but when skin is completely dry.
Put it on at around the same time every morning, give or take a couple of hours. (If nothing else, this helps to make the application part of your morning routine so you're less likely to forget.)
Spread it on as large an area as possible, avoiding very hairy areas.
When you can't squeeze anymore out of the sachet, cut it open as there will be a small amount left inside.
Don't put it on your downstairs, it stings like a mofo and doesn't make any difference to growth.
Hope this helps
