I know lots of people have used the bonus dose in the 2.5 pen as a stepping stone to the 5 pen, as the bonus dose seems to have more than 2.5 in it.
Does anyone happen to know how much is in the bonus dose for a 5 pen? Im on 5 at the moment, I have another 5 pen waiting to go in the fridge, but I thought I’d try and use the bonus dose first if possible. But I was concerned it might be too much.
