Hello Fidalgo!
Each 5ml of the syrup contains 2mg chlorpheniramine maleate and 0.5 mg dexamethasone. Usually 10-15ml before orgasm is enough and the same dose next day in the morning. if you have POIS permanent downsides like I do, it might be helpful to take it on No-orgasm days. please, consult a doctor first tho and read about the side effects and contraindications to avoid any risks.
It helps me with OCD, makes orgasms more enjoyable, suppresses my stress and lessens my dissociation problems. it works as if it eliminates the side effects and gives my a brain a chance to recover.
The brand name is Apidone. It's a locally produced over-the-counter drug in Egypt.
