I'm curious who has used both and if you could share the differences between the compounds? If I use Mast, I plan to use Mast P b/c I like short esters. Also, Mast is notorious for being hard on the hair line. I'm curious if Primo is the same, less or not at all bad on the hair line? I really want to use Primo but I don't care for long esters except Test and it also cost substantially more so just looking to get some answers. Thx for any input!
