I had 3 unsuccessful attempts of HRT, all of them about 6 months long and I saw almost no effects. Now, the fourth attempt is already succesful, so I will share what was the difference and you decide by yourself if it is applicable for you:
The first attempt was on Estrofem and Spironolactone - both taken orally. No effects at all... only small buds behind the nipples, hot flushes and better sleep.
The next two, I was taking Spironolactone and Finasteride orally, but the Estrofem sublingually and have better effects, than before, but still insufficient, although I was on pretty high Estrofem intake.
The fourth time (now - almost 15 months) - Estrofem sublingually, the first seven months - Androcur orally, and after my 1 year anniversary - micronized progesterone sublingually.
Beside the medicals, there is one very significant difference between the unsuccessful attempts and the successful one - before my last HRT, I was drinking a lot of beer and whiskey and smoked two packs of cigarettes daily, also smoked weed quite often. I was eating almost everything, which doesn't contain meat (I am vegetarian).
Now I don't smoke anything and drink almost no alcohol - sometimes I drink 1-2 glasses of red wine or beer and nothing more. I drink a lot of water and I don't eat junk food.
