bro depends where you got them...if you got from a good brand like sarms1...osta mk2866 is 50mgs = 1ml (1ml = 1 dropper)...nolva and clo and aroma depends where you got it...should say mgs/ml on the bottle
It is very hard to tell it like this. Different brands have different concentrations (mg per ml), and different size droppers. You will need to be a bit more specific here.
I don't want to give out dosing instructions unless I know the concentration per mL. It changes depending on where you ordered the products from. It's a very simple formula.
Take 40mg and divide it by the mg/mL to find the required mL.
For example if the product has 20mg/mL -> 40mg / 20mg/mL = 2 mL
