I doubt it’s not enough. Used 1000iu’s of Pregnyl per week for quite a while recently.It doesn’t even seem like you used such large doses of HCG though, which is what is generally concerning.
Though I wonder if you’re lack of response is due to too much HCG, or not enough.
I did do HCG mono for a little when I first started. 2000iu’s/ week. But just looked back and I was only on HCG mono for roughly 6 months
