Now everyone is going to want to know which lab it is!
Primobolan - methenolone - is a little more expensive to make, which is why the cheesy labs don't bother. They'll give give you low dose T and say it's Primmo. But vets will know and the lab will soon fall by the wayside like so many others.
As an aside, I don't understand why A-Stealth is so ofen mentioned in the open. If I were buying anything I wouldn't use it for that reason alone.
