It would probably be closer to 0.80 Ml.
As 0.75 would be 7.5 + 3.75 = 11.25........................ JP
P.S.
Half an 0.50 Ml would be 7.5 and half of that or 0.25 Ml would be 3.75
Everyone is different. Some people need high estro to feel balanced. Started at 12.5-15 EOD and adjust. I feel my body needs more estrogen to be balanced so now i just wait until i see minor signs of high estro (bloat, puffy nipples) before i use aromasin and my libido and mood has been fantastic lately!
True, everyone is different. Im not one to quibble over 2.5mg so I end up going with 1ml/15mg. If your ardent on sticking with 12.5mg then cross multiple then divide. So, if 1ml yields 15mg then 12.5 = x. Or 0.83ml
Start with 10mg EOD and increase from there if needed. 0.66mL will be equivalent to 10mg.
Remember that some estrogen is needed for normal muscle gain and sexual function. You don't want to bottom out your estrogen levels. You just want to keep them in the low-normal range.
It is better to start on the lower side, so do just 10 mgs EOD to make sure that you don't crash your estrogen levels. If you see that you still need more, only then increase the dosage to 12.5-15 mgs EOD.
^Truth! I happen to be a bit more susceptible to gyno. Through trial and error I found the dose that works for me. That happens to be 1ml/15mg QD. Going EOD and I start to feel that subtle nodule coupled with mild soreness.
