At 700 tren a,and decca 300,it lactated a little.It was very small,not even a drop.Took caber and dropped my tren dose to 50 ed.A week and it was gone.I wasnt that worried cause i knew that lactating didnt mean gyno! Witch does scare me.If you give it a shot id run decca for 6 weeks,then add the tren ace.Just because you could have a more pile up effect if you run tren a, and then the decca kicks in,you could have a shit load of pro's kicking around.IMO.Most people only run tren for 6 weeks(most,lol)And it take that amount of time for decca to kick in.So if your running tren for 6 and drop it,your decca is just kicking in.Your not getting them both at the same time.Of course NPP would be different,and might be a better choice if you want to give it a try.Since both ace and polyprop will clear quickly.Caber on hand would be 100% smart.
