Sorry for the unfamiliar English. I have a PFS since September 2020. I am currently taking arginine citrulline and Tonkat Ali for treatment. Arginine citrulline has a positive effect on wood in the morning, but it worsens and reduces erections and semen volume during masturbation. Tonkat Ali loses wood in the morning, but increases erection and semen volume during masturbation. These supplements should have a positive effect on all sexual functions, but why are these differences? Before PFS, I took these supplements on a regular basis, but only had a positive effect. Can anyone explain the rationale for this result?
