You and Luki are spot on.
I don’t think Hex is some magical potion like some people do, Tren is Tren at the end of the day.
But for whatever reason I had zero sides and great gains and bloodwork on Hex. I’m not a science guy at all, but my theory is that specific ester works very well with my body for Tren, keeping things very stable. If I remember correctly it’s a longer ester than Tren E.
But effects wise, Tren all does the same thing. Ace a little faster with more of a kick, but the instability in blood levels may cause more sides.
Day 1 stuff I don’t need to deep dive into
I’d say for older guys worried about Tren sides and are going to use Tren anyway, give Hex a try. I injected it daily too (all my gear is split up ED), which may have helped too
