Having run both, I had signs of obvious liver strain on superdrol, ie dark circles under the eyes, loss of appetite, lethargy, etc. In addition, superdrol has caused some serious drops in HDL, some approaching 0. Superdrol has been theorized to cause upregulation of the ERs as well, which is the explanation of the delayed gyno. I went hypoglycemic numerous times on superdrol as well, the only other thing that caused this before was tren. superdrol caused my low blood pressure to be elevated to high-normal. Having said that, superdrol was my first steroid and the gains were very good, but in retrospect, it wasn't worth it. Did you see the news paper articles about hospitalization associated with superdrol, or at least its clones, which "may" be another steroid.
As for epi, I have an allergy to sulfer meds so taking this compound is a big risk for me, so I have not done so. However, all of its properties are based on it being similar to its unmethylated counter part, but if you look at the difference between dianabol and boldenone you see that this logic can be faulty. In addition, we are arguing if this chemical breaks down in the body to another steroid, the fact that we don't know shows how little we really know about this compound. Also, since its a non-aromatizing androgen, evident by the gained hardness, its likely that it is more harsh on lipids than a testosterone derivative such as DMT.
Maybe my original statement about "much safer" applies more to superdrol and just "safer" applies to epi. At least with DMT we have SOME research in english and a good bit of people have used it on a broad scale.
