Excellent!
It helps my acne a lot. I have PCOS and have been suffering from outbreaks since 5th grade! I'm in my late twenties now. I discovered this brand (sustained release) about 23 years ago. It's been great since then. I am taking 2 tablets in the morning and 2 tablets in the evening (4000mg a day). You will definitely know when things are gone. If I can go without it for just a few days, I usually get at least one large cystic acne. I firmly believe in something like this and I like it staying in my system for a long time so I don't have to take any medicine during the day (like other PanAcid followers).
