[4] Pink Triangle Sdn Bhd was founded in 1987 to provide a telephone counseling service for HIV/AIDS and sexuality issues.

[5] PT Foundation is the first NGO in Malaysia to offer HIV/AIDS testing, counseling, prevention, support, referral and care services.

[5] Being a member of the MSM community and life partner of Hisham Hussein, Raymond Tai, the chief operating officer of PT Foundation firmly believes that the battle to eliminate stigma and discrimination of HIV/AIDS involved a shift in how soon Malaysia could move from a conservative and judgemental society to one that embraced diversity, irrespective of one's race, religion and sexual orientation.

[7] PT Foundation provides telephone and face-to-face counseling, anonymous HIV and STI screening, outreach programmes, and support for key affected populations mainly drug users, sex workers, transsexuals, men who have sex with men (MSM), and people living with HIV/AIDS (PLHIV).

The centre is managed as a social enterprise, where beneficiaries of the programme e.g. the MSM community have to pay fees for HIV and other sexually-transmitted diseases tests and counselling services.
