Epistane question

[Flexappeal]

I am starting a havoc run Feb 13.
I have 2 bottles of Epistane. One is from a while back its the very first generation RPN epi. I bought it when it first started coming out, its actually expired by a few months. Looks like this:

2a,3a-epithio-17a-methyl-5a-androstan-17b-ol

I've decided to run a 6 week course instead of 4, so I just purchased a bottle of IBE Epistane. It looks like this:

2,3a-epithio-17a-methyletioallocholan-17b-ol

Why are they different? I need to integrate both of these in one cycle. Do I mix or do one before the other?

Bump..

They are exactly the same, just written different, both are Epistane.
I asked this very same question myself a while back. No problems using both to complete your cycle.

i've mixed different versions on the past with no problem at all. epi strong and epivar
