Ya never know. Even if it's legit it may be under dosed or even not that clean. Always worth the extra money on labs with good rep. As well patience to source out. The bottom line is your adjusting your hormones which is a risky thing to begin with. For me I better be getting legit stuff to help me augment my cycle properly for best health during, post and of course long term. Take your time as there is a wealth of knowledge on here so do homework!
