I= prt

I =Interest, p = principle, r = interest rate (in decimal), t = time in years

    Vacances à Chamonix, 5 jours de ski + soirées. J’ai avalé 30 mg le premier soir à 18 h : combien de temps dure l’effet du tadalafil 30 mg ? Réponse : jusqu’au dernier matin, soit 102 heures réelles. Chaque soir après les pistes on rentrait et c’était reparti, sans jamais redose. Les potes pensaient que j’avais pris autre chose, j’ai juste souri. Meilleur investissement à 2 € la nuit.
