Phera-Vol. Pheraplex + What other compound? Confused!!?!

[njt11]

17a-methyl-etioallochan-2-ene-17-b-ol
17-methyl-delta-2-etioallochane

Correct me if Im wrong but isn't JUST the top part pheraplex?
Can someone tell me wtf 17-methyl-delta-2-etioallochane is?
Phera-vol is the only clone I could locate at this point in time. Methyl-Plex is out of stock everywhere and original Pheraplex is long gone.
I dont wanna purchase something and not know what part of the compound is. I also don't like the fact that its 15mg, whether its 10mg Phera + 5mg whatever or 15mg Phera (Cant do 10/20/20/30 ugh).

A very popular auction website has Methyl-Plex listed by one seller. If only I could think of the name of the site...gah...Some letter, and then something referring to a body of water...
