Yes you can but if you don't have some test it can bother you errectile functioning as they are both similar with that negative side effect. If that doesnt bother you then go for it. Tren can make the joints sore while deca can eleviate joint pain.
You run the risk of too much prolactin build up as all of those are androgenic. I would run one or the other. Dostinex (cabergoline) or bromocriptine should be run in conjunction to prevent this problem/side effect.
Yes this is true, but some of the sides can include puffy lactating nips. Prolactin. Dostinex (cabergoline) is a lactation inhibitor. Some may experience this with too many androgens running around in the body and converting or causing a secretion of prolactins from the pituitary gland. progesterone in women tends to inhibit lactation so one would possibly expect the same in men. But the sides which many complain about are puffy lactating nipples. This comes from a build up of prolactin in the body.
