PrEP through the GGD
The cheapest way to get PrEP is through the GGD. All necessary check-ups and tests will be done every 6 months for free by the GGD. You pay the pills yourself. You buy them at a pharmacy using the recipe you get from the GGD.
Sadly, the waiting lists at the GGD are full. Sometimes a spot comes free. Ask the GGD what is possible for you.
