Tren always has a "rusty" look to it, that's why it looks more legit than not.
The biggest travesty here is paying $120 for 10ml of tren! My lord man, find a new supplier! Tren A shouldn't cost more than $80. $140 for mast is crazy too, but if its real and properly dosed then it might actually be worth it.
Yes the tren looks to be the right color but it is underdosed and can still see crystals in it. At 100mg/ed and isn't even doing much.
But yes it's harder to fake tren because of it's color. The mast was pure shit/oil an you won't be able to tell as it's clearer solution with a slight tint.
And this guy isn't a supplier to me anymore. Confronted him politely and pretty much told me the solution is not buying from him because he knows it's legit. Not sorry let me send another vial, or work something out. Nothing pure bullshit and getting defensive when I was polite. Right there proved to me that's the assholes who just want to make a buck. Disgusts me.
