Deca and estrogen

[csky]

How severe is the aromatization of deca. Incase you recognize me I still am sticking to test e cycles until I reach my potential before adding another substance. This is topic is a question asked by a friend if he should use estro blockers or not sweat it unless he sees gynecomastia coming in.

The transition of deca is not the same as basic test you would use something like proviron for it but at the dosages used probably not needed at all I personally have never had any issues and have used deca a few times at 600mg a week hope that helps

Deca aromatizes but not to a high degree (about 20% less the test, off the top my head). if you ran a low dose of test with a moderate dose of deca you could get by not running an AI at all.
eg. 150mg test with 400mg deca.

if your estrogen sensitive at all though then you'll want to run an AI with every cycle . also keep in mind Deca is a nandrolone, it will illicit progesterin and prolactin actions in the body, and if your at all sensitive to that then you could get leaky nipples or gyno.
keeping estrogen in check and running a dopamine agonist like prami or caber is the best 'pre-caution'

also , you want to prevent gyno , not wait till it happens and treat it after the fact. running a serm on cycle is another option

Also running blood work mid cycle would be a big plus to learning what you do and don't need.

I recommend that you run an AI when you run any cycle. Why? You don't know if you've got a body that is gyno sensitive or not. Why take a chance? Even if run .25mg every 3rd day, controlling E2 goes a long way.
