It's a known irritant, along with boldenone propionate. A few guys still sell it but be weary of anyone who says that theirs is painless. Maybe in a concentration of 25mg/ml, but anything more will be crippling to most.
My source had it along with bold cyp.....it was making everyone really sick so he quit selling it...he actually offered a bunch of free vials of it...but i dont need to get sick from an experiment....
I'm going into week 3 with the cyp...to early for me to tell right now...
