I dunno, guys. I haven't read up on this stuff in a few years, but I do recall reading that tren degrades in higher heat (like, sterilizing heat) and anavar just straight degrades sitting on the shelf.
Anecdotally, I am only 210lbs now, very lean, trying to stay on the healthy side. Back when I was actually 260+, already very strong in D1 football and track,, I took SPA anavar that was 2.5mg each pill, individually sealed in a small aluminium push out thing (because it degrades maybe?) . Shit was EXPENSIVE for a broke ass college student. Used the old pyramid 1 on day 1, 2 on day 2, up to day 4, then back down (so 10 mg / day at the highest) and got stronger than I've ever been since. 10mg and nothing else at all...take that FWIW. And back then, 10mg was four whole pills! I felt like it was maybe excessive.
Before that, a couple years earlier, my first "cycle" was half a bottle of 2609 Syntex Anadrol. 300 bucks for the bottle in about 1991. So broke...anyway, that's where it started. Incredibly strong, and still in the first week. And my diet was the "see food" diet...high cals and generally terrible. And I (idiotically) took it sublingually the first few days LOL. Until under my tongue, I saw perfectly round, bright red blood blisters on like the third day. God knows how my liver felt about that stuff.
Never ran Tren back then. It was a myth to us. Kinda glad now, as I'm pleased with how "strong" it is when I do use it these days.
But hey, other hand, gear is way more available now and we've got choices. I can't complain.
