Why though? I mean what is the advantage of running mast/primo without a test base?For me HCG provides the missing Test and Estradiol.
But yeah, EQ, Masteron and Primo work fine on their own
Make sure you use enough of them. At least 600 mg per week, preferably 800 mg or even 1g. Most preferably add some 200-250 IU HCG per week.
