Here's what they said
Trenbolone color varies by the amount of heat that the raw material was exposed to during manufacturing as well as the temperature at which the raw has been transported/stored at since its conception. It is important to note that the color of tren in its finished form has no bearing on the product's potency and is merely a cosmetic condition. As long as there are no impurities floating within the oil, or settling of particles when the product is left sitting for an extended period of time, then it is perfectly safe to use and we guarantee that it will yield the desired results.
If however, the use of this product causes you concern, we are willing to reship the same product containing a different color tinting.
