Be careful with re warming tren. Tren oxidizes at a lower temperature. If the golden color starts to darken up on you then you know it’s starting to oxidize. With tren, if you start to get crystals I prefer slowly warming it up in water on the stove top while swirling to get it back into solution. If you have access to benzyl, then a drop or 2 will put it back into suspension as well.
tren can be trickier than most other gear when it crystallizes because of the heat point.
just my 2c
