Are you referring to "ON Cycle" made by Fizogen???? To be honest with you bro I have never tried the product so I cannot comment on its effectivness. However, Fizogen has a pretty bad reputation overall as a company. Many of their products are underdosed and to top it off, the ads for their products make them sound like actual steroids, which is total BS.
I would try to look for something else if I were you.
However, to answer your original question, I would make 100%sure. Better to be safe than sorry.
