or simply time.
When you start using test it may very well take some time before a side like acne appears, so it might simply be that had you stayed on test e for this long the same would have happened.
Or it may be E2 spikes from the prop.
Or it may be the SERMs,
Or combination of all.
(Diet can also influence this)
In short, asking WHY it appears is much less fruitful than asking HOW to deal with it in this case.
