Keep in mind in old literature, Primo can be seen to have a slightly higher androgenic rating in the A/A ratio compared to mast. How reliable these rating values are has been debated.
Whats consistent is that most vets/experts will tell you the androgenic side effect profile of masteron on hair are more noticeable than primo. Primo is still hard on hair. Test + finasteride is best. Nandrolone is hair safe but only if not running finasteride. Don't combine the two or it's worse due to 5AR keeping nandrolone a more androgenic compound (moreso than methyltest when enzymatic conversion to DHN blocked).

These 2 are absolute authorities imo.
