Tren No Ester, without a doubt, IMO. At least, 25mg of Tren Base outperforms 500mcg Mtren. I haven’t tried larger doses of Mtren at once, so 1mg might be different. Tren Base isn’t usually brewed higher than 50mg/ml (apparently it can crash above that).
But also, different feels - Mtren is more positive drive, closer to euphoria for me, while Tren is seething rage. You could even stack them (in the same shot even if you get oil-based Mtren, which saves the first pass on the liver). Again, this is a discussion about acute use on important training days, not courses of these as an anabolic agent. There are much healthier anabolics that work better for that.
Yeah I’d agree it could be useful for sex.
I’d rather use Trest or Proviron for enhanced sexual experience, but from a health perspective TNE or something like androsterone is probably the healthiest options for that.
