Can someone explain this structure

[Old Guy]

1-dehydroandrostanolone-17-cypionate - This is the structure for Dazed's 1-test cypionate

17-hydroxy-5alpha- androst-1-en-3-one - This is the structure for 1- test according to an article by Big Cat on BB.com.

Can anyone explain the difference?

 

[sethroberts]

no difference

they both describe the exact same molecule, just differences in the interpretation of the nomenclature system.
