Here's some data. Dinh lang extract and deprenyl have some additive effects on prolonging the lifespan of OFA-1 mice. (Acta Physiologica Hungarica 79(2): 119-124 1992) GROUP MAXIMUM LIFESPAN control 133 weeks dinh lang 170 deprenyl 162 both 180 This also works in Wistar rats as well. (Acta Physiologica Hungarica 75: 301-302 1990) GROUP AVERAGE MAXIMUM LIFESPAN LIFESPAN control 147 164 weeks dinh lang 180 194 dinh lang & 206 239 deprenyl The life extending effect of dinh lang extract appears to be quite real as it has been demonstrated in two strains of rodents. Moreover dinh lang appears to be more effective than deprenyl. In addition the dosage used was probably suboptimal. Only 10 mg/kg extract was used in the life extension experiments, while maximal effects of passive avoidance performance in young OFA mice was found at 20 mg/kg. (Acta Physiologica Hungarica 75(1): 69-76 1990) In Wistar rats aged 22-24 months 20.8% resumed full scale sexual activity at a dosage of 20 mg/kg, 11.5% at 10 mg/kg, 7.7% at 5 mg/kg and 0% for controls. (Acta Physiologica Hungarica 75(1): 61-67 1990) It would be interesting to see more research on dinh lang, especially at the 20 mg/kg dosage.
