1-No matter how many times you hear it, Epi has NOT been discontinued, its been harder to get because the demand has always exceeded the supply.
2-No you did not purchase a fake bottle, the website is a legitimate business who would have no benefit in ripping you off.
3-Black tops are whats on the bottles now.
4-The bottles are what IBE was/is/are/were making and putting out around the time frame you got yours.
5-bad batches, based on questionable testing methods, questionable chain of custody, questionable motives, etc, etc, Im not getting into that, just wanted to say take everything you read with a grain of salt.
