in my experience, it's usually a scam of sorts.
are you expecting to really 'feel' 50mg of tren/mast/test?
in my experience, suppliers will underdose the shit out of it and charge a stupid price, especially when they know you'll be looking to drop weight and water, and you'll . tren and mast run the same price to produce, but the test is cheap as hell.. you're probably lookin at 30mg tren, 30mg mast and 50mg prop in each cc... if that. plus, they know you're probably gonna be either using multiple cc's per shot, or shooting everyday, and they can get away with putting less in the mix.
better off buying everything separate.
