Just did some quick research!! Signs of counterfeit Oxyelite Pro:
1.) # of pills is more or less than 90. (one example from someone who received a fake Oxyelite) :I have 4 bottles, 3 are 90 ct, 1 is 180 ct..
2.) various lot and exp #.
3.) One bottle in particular has no effect whatsoever and I have been using OEP for a while
4.) The label is different form the other three, ("R" vs "TM")
5.) Above USPLabs logo, different color purple
6.) Ingredient list does not end in "...bark extract"
7.) The picture of the capsule has squared off instead of rounded ends.
8.) The printing and font look different and altered. All 3 known good bottles are consistent versus the above mentioned oddities.
Hope this helps! I'm definitely thoroughly reviewing my 3 bottles I bought off Amazon vs my legit source
