SHIP Clinic (Sustained Health Initiatives of the Philippines)

Highly recommended: SHIP Clinic offers free testing for HIV and a variety of other STDs/STI’s. I like SHIP for their extreme discretion with your identity and results coupled with their affordability (they’re free for most STDs/STIs!). Walk-ins aren’t allowed however, so you’ll need to phone them ahead of time to schedule your visit to be sure you can be accommodated.
