The reason I'm concerned about my tren experience was I got aggression but basically nothing else. No insomnia, no night sweats, no increase in strength (that couldnt be accounted for elsewhere). I've got another brand to try though once my PCT is over so I can compare but I was realllllly dissapointed. 3000+ cals a day is what I was eating. 120-180g protein per day, which isn't super high, but I'm only sitting around 195 so its decent.
Another thing to consider is a source can unknowingly be using bad raws. He could have paid top dollar from a very trusted and close supplier who he has a great relationship with and has never had any problems, and end up with a bad batch. Could point to lazyness, but I think it doesn't necessarily mean malice or greed (it definitrely still could mean that). We don't trust sources when they post their own tests so the onus is on us to test it ourselves, which can be time consuming and sometimes impossible depending on location and security and finances.
Theres really no way to win, but thats the black market for ya.
