Obviously not. There’s estrogen (as you mentioned), possible prolactin, usually cortisol. If a lot of test was used, just dropping that probably causes some loss.
I think you’re thinking deeper into this than I had intended.
If on TRT, one of the issues, test suppression, is less of an issue, so some of those losses are reduced. As you’ve mentioned time and again, cortisol is one of the biggest issues when coming off cycle.
So bulking SARMS also have cortisol issues too coming off?
