Are you experiencing any estrogen related side effects? If not I would keep it the same...if yes increase the dose until they diminish or until you exhibit signs of low estrogen.
This is a snippet from another board; I do not take credit for typing this up but a very useful tool I use.
High estrogen sides
Acne, loss of libido, water retention (Bloat), pissing less than the water you consume, moon face, very small testicles, scrotum hanging too high, soft testicles, extreme oiliness all over, aggression (roid rage), depression, bitchiness, lethargy, insomnia, soft erections, extreme cravings for sugar/chocolate, high bp, bp spikes, enlarged prostate, pressure in lower abdomen when urinating, thin stream, constipation (from water retention)
Low estrogen sides
Dry skin, dry lips, dehydration, loss of libido, good morning wood no wood when its time for sex, loss of wood while having sex, loss of sensitivity, dry gland (penis), white gland, loss of girth, irritability, mood swings, crying for no reason, dht rage (aggression you take out on others), dull orgasm, hesitation just before urinating, night sweats, loss of appetite, constant fatigue, lethargy, constipation (due to dehydration), diuretic effect (pissing more water than you are consuming), itchy scalp, obsessive thoughts
Of course YMMV, I got each and everyone of those sides the past few years I have been juicing and I am sure I am forgetting some sides. When you get one side effect it is just an indication use this list to make a full picture. So say you have loss of libido, no zits and dry skin/flaking you know your e2 is low. Say you have loss of libido, acne, uncontrollable aggression, and bloat you know your e2 is too high. Never go by one side only, being bloated only means nothing, having dry skin only means nothing again.
Hope this helps. Treat estrogen like the money in your wallet, one of the most important things to control for us.
