it comes in ace and deconate forms yes. so it can be done dail eod or weekly with the deca ester. i have used it in the past with no test at all and it can be used with test. it does not impact health markers for some people and it is strong as shit but and this is a huge but. if you have esro issues it will absolutely wreck you big time and that's where the issue with health markers come in. if you have to run a serm or other form of estro control it will wreck your markers.

is it good for replacement? yeah if you are good with estro but on a side note it will shut you down worse than test does. i like to add in in when my health markers get wonky and need a little boost to my hrt but i as i said i dont have estro issues. so i am good with that.
