2 progestin based steriods?

Would taking 2 progestin based steriods like decca and m1t cause instant gyno?

depends on the person..

i wouldn't risk it..

Bro, Ive ran Tren and Deca together, and I know a few people who have also ran two progestin based AAS at the same time for long periods, and none of them experienced gyno symptoms and neither did I. Although everyone is different...how my body reacts may not be how your body reacts, but I would say go for it, as long as you ran some test as a base, as deca/m1t will shut u down hard. However, i have to say that stack looks very, very poor, and you should consider using something else altogethor.
