If it's methenolone ACETATE (injectable) and it says Schering manufacture, be very wary since Schering stopped manufacturing that product some time ago. They've actually let the patent expire, last I heard. Most of the ones I've run across have been bogus, due to high demand and very low legitimate stockpiles.
If it's methenolone ENANTHATE (Primobolan Depot), Schering still makes that by the swimming-pool-full.
Can't really say if it's legit or not since we don't have a pic - counterfeits are usually spotted by looking at DETAILS, not via overall description. I hope for your sake (and your wallet's) that they're the 'real deal Holyfield'.
