Indeed, 95% of Primobolan depot is fake and it actualy contains Nandrolone phenylpropionate, vitamin E or even Progesterone. However, Schering products are easy to recognize.
1. Both Primo depot & Testoviron depot are prepared with very thick oil (Castor oil) which is completely colorless.
2. If you rub it on your hands and smell it, it should smell like rotten raw peanuts (somewhat unpleasant).
3. Oil is completely tasteless.
4. Freezer test is always negative, even after few hours of deep freezing, oil will stay completely clear.
I know this info sounds weird, but I got my gear in a pharmacy with prescription, so I guess it's real as it can be.
Just do a freezer test, if oil turns white - it's fake (Nandrolone P.), and if it doesn't, taste it and smell it.
Also, real Schering's are very easy on your glutes, I never felt any pain or burn.
