I've been taking the really dark orange Tren for 3 weeks now and the dreams and aggression are getting a bit heavy so I'm thinking I'm not ready for this yet so I'm going to lay off it until I've another few cycles under my belt. So the dark gear seems to work rather well for me anyway but everyone is different.

Ideally yes, but tren will be tren, up to 5x more anabolic and androgenic than test. So dark tren ligh tren either way you look at it its going to kick your ass. In my exp the darker the more pip, but there is a lot of diffrent factors which will cause pip.

Who's got clear tren?

Tren will oxidise when heated past its melting point the more heat the more it will oxidise = the darker it will go tren should be a light brown color ,this shows its been melted to the exact melting point or just above as doing this will stop any dammage to the hormone itself ,very dark tren is an indication that too much heat has been added and in turn can result in a dammaged hormone leading to underdosed gear. Raws can also play a role in how dark tren turns out. You should be fine bro.

It's something to do with the heat put in to it I was once told by someone who had the top site on here before he closed shop

As a well kown home cooking source who just closed down once said:

As little as 1% change in the impurities in TrenA can change the color.

TrenA is a cattle feedlot substance, not bovine (that's a cow), (male, female or other) ever lived to tell the whole story.

ETA: You can pretty much bet, the raw powder is not made to pharma standards.
