It is the exact same compound, I would assume down to the raws. The original SuperDrol clone, SNS's Methyl-DrolXT was initially mislabeled with the b-isomer; however, sources confirmed that SNS's Methyl-DrolXT was of the exact same raws as Anabolic Xtreme's SuperDrol. Whether AX's SuperDrol was of the same raws as Designer Supplement's original production run is unbeknownst to me.
At any rate, that is besides the point: CEL's M-Drol is bar none the closest thing to the Methylmasteron standard you will find. No offense to the OP but, I am continually surprised that people are willing to stuff Kilosports Mega-Oxy-Bol with no reference standard into their face yet readily question a product confirmed to be the original!!
