tren will have a gold color to it.. either dark or light, it's always gold. doesn't matter if it's from fina/pellets, or raw, it's gold.
you can taste it and smell it seconds after you shoot it.
you don't always get the cough. it'll vary shot to shot. I've had guys wonder what the fuck the cough was and since they never got it, they thought the stuff was underdosed or not tren, but then one day, 1/2way though a bottle, ka-boom I get 15 texts from'em thinking they're dying of a heart attack and doubled over on the bathroom floor asking what to do. lol.... then they apologize for questioning the quality of the product. lol
tren makes it damn near impossible to bust a nut also. with a few g's of test in you, and prami and 75mg Viagra and 10mg Levitra (Cialis sucks), you can fuck for hours... until you're exhausted, dripping with sweat, and she's sore, you end up being the one either faking the orgasm or just saying 'fuck, that's it for me.. i'm good..' because you absolutely cannot bust a nut. lol
a week after your last tren dose, and you're bustin a nut in 5 mins. lol... 30 sec's if you wanted to. lol.
