I can't agree with that rationalization at all.Tren can still cause a plethora of irreversible health issues tho even when done "correctly". Slin is extremely safe as long as you know how to read a syringe lol.
If you screw up the number 10 and 100 I'd argue u might be dumb enough that something else would've killed you soon anyway.
Slin vs Tren when looking at implications on health... I'd stick with Slin all day.
However neither should be used by beginners or even novice trainers
Insulin is far more dangerous then Tren... One screw up can make you....uhhh die.
