Hey has anyone tried to produce a supplement that mimics Activin?

Increasing sperm production can be useful for our community here especially if combined with DAA or another product that might increase testosterone post cycle.....

Activin and inhibin - Wikipedia, the free encyclopedia

Lots of Pub Med research on it also.....not sure it would be bio available but it is dimer so I am not sure if the molecular weight is low enough for a transdermal etc....?
