Contraindications: Yohimbine is contraindicated in individuals with diagnosed hypertension, cardiac arrhythmia, anxiety disorders, renal impairment, or liver disease. It must not be combined with monoamine oxidase inhibitors (MAOIs), selective serotonin reuptake inhibitors (SSRIs), or any other sympathomimetic agent. Pregnant or breastfeeding individuals must not use this product.
Side_Effects: Elevated norepinephrine secondary to α2-adrenoceptor blockade can produce: tachycardia, palpitations, increased blood pressure, diaphoresis, anxiety, tremor, and insomnia. These effects are dose-dependent and are most pronounced when yohimbine is taken outside of a fasted state or combined with stimulant compounds. Gastrointestinal disturbance (nausea, diarrhoea) is reported in a minority of users.
Monitoring: Blood pressure and resting heart rate should be measured at baseline and weekly throughout the cycle. Users with borderline hypertension should not exceed 12.5 mg per session. Cease use immediately if chest tightness, irregular heartbeat, or severe anxiety occurs, and seek medical evaluation. Do not exceed 25 mg per single dose without medical supervision.
PCT: Yohimbine does not suppress the hypothalamic–pituitary–gonadal axis and does not require post-cycle hormonal therapy. If yohimbine is used adjunctively alongside anabolic androgens, any PCT protocol should address the primary androgenic compound; yohimbine can typically be continued through PCT without interaction unless the PCT agent is adrenergically active.
