What are you talking about?
androstenedione, androstenediol, 5-androstenediol, among others will all aromatize and they are definitly pro-hormones.
Pro-hormone means the hormone being taken CAN be CONVERTED to some other hormone in the body like testosterone, deca, boldenone.
That fact does NOT preclude the said hormone from ALSO having steroid like effects WITHOUT and BEFORE it is converted.
So PH can convert to testosterone or estrogen for example, but can also have steroid like effects in their native form.
Then we have the pro-steroids which are HORMONES which have steroid like effects WITHOUT any conversion and this includes stuff like 1t, etc.
It's rather hilarious that some can't get their heads out of their nether regions and say 1T isn't a steroid when it is actually 1-testosterone. How much closer do yo want to get?
