Hair Safe cycle while on fin

[Twisted45]

Been on gear for about 10 years. Recently started taking finasteride to help with my hair loss and has helped a ton. I now want to do a cycle but not sure what to use. Going to be using test at 500 for a base since I know fin works relatively well on test. 19nors are out since they are basically counterproductive on fin.

Any suggestions on what I can stack with the test. Primo? Also heard it's pretty harsh as well though.

Orals?

Ostarine?

Any help would be appreciated !!!
