Here. The secret to make BO disappear is

85% Dutasteride + 15% Accutane(Accutane works synergistically with Dutasteride. If you take Accutane without Dutasteride it is going to increase your BO)

After it’s 99% removed,

Clean with Neutrogena Deep Clean for your pits.

And put on some Talc with coffee grounds.

The above works like magic but the MAIN biggest charm is still Dutasteride without that the rest is nothing.
