Nothing wrong with trying forma, but if you can get the doc to test estrogen and prolactin and prescribe the appropriate pharaceuticals, that would be the better route, and probably cheaper.
If you are suffering symptoms of aromatisation, it will definately help. Forma Stanzol contains formestane, which was a prescribed AI, in the USA and elsewhere, until it was pulled because the FDA and others thought it was too anabolic for an anti-oestrogen product. I've used Arimidex and other products before, and while Forma is milder in side effects than Arimidex (and significantly cheaper too) it is just as effective at controlling E2.
An additional bonus effect for me is the one FS has on my sex drive and well-being. I feel really happy and find it enhances mood with higher doses. I'm also always in the mood for sex, and in all my twelve years on HRT I've never felt this sexually wired before. Honestly, Geolift...I hope you have the same experience I've had on this stuff. It honestly is that good!
If you are getting effects of aromatisation I'd start at 4 pumps day/night for a few days and see how you go. If you want to knock it up, then add an extra pump per application. (so two extra pumps a day). For controlling E2 you shouldn't need more than 5 pumps (twice a day).
