I would try some topical DHT blockers, i.e., Nizoral shampoo, spirolactone, etc. Also, I have been using topical products from Dr. Proctor, Texas, for over 20 years and he has a good reputation. I also use Proscar, which is 5 mg's whereas propecia is 1 mg. The 5 mg is much cheaper to purchase over the net. A lot of guys quarter the 5mg tablets but I just half them and hope that the additional mgs will help. I also use emu oil, which is proported to help with the frontal loss. I just started my first cycle of Sustanon, so I can't directly answer your questions regarding Deca. However, as I mentioned it previously, I would try the topical applications. Just Google Dr. Proctor and read about him.
