Iba-iba talaga ang presyo depende sa clinic, but from what a few of us tried, private OBs usually charge around 300-500 pesos per injection, while lying-in centers tend to be cheaper, sometimes 150-200 lang. Good thing you're exploring injectables since the pills didn't work for you, but I'd suggest calling ahead sa mga clinics near you kasi tulad ng center ninyo, mabilis maubos sometimes, mas mura pa usually kung may standing orders ka with them para sure laging available!
