I contacted janoshik last month about testing enclo.
I asked him:
His reply was:
What did you ask him to test the enclomiphene for?
Seems that he would have tested for both clomid isomers, but if you didn't specify, who knows. It does seem odd though. I'm wondering if the other 37% could possibly be the zuclomifene isomer of clomid?
There has reportedly been clomid sold as enclomiphene. The only way to know for sure would have been to test for both the zuclomifene and enclomifene isomers AFAIK.
Edit to add info:
