Honestly boss, I have absolutely no clue. I'm a user of UG juice, have been in the game in the game for about 20 years and have not the first inkling of what color different carriers can turn. All I know is tren=dark and tren=bad (for me) so I'm just doing a little investigating here. I could just as easily toss it, but figured I'd see if anyone had some ideas on the subject, first. I mean hell, it's not like we're not already taking a gamble anyway actually INJECTING stuff from someone we have never met before. Who knows what kind of lab conditions and sanitary environments went into any of these products but we continue to do our thing. I just know that tren turns me into a basket case and I guess I'm willing to risk unsanitary brewing conditions before I put myself through that nonsense again
