Yea I can attest that two weeks of tren at 200mg/week turned me into some kind of beast. My upper body strength went through the roof, and I could recover between sets of dips like wolverine. I added a permanent 5 lbs of muscle and for the first time got backne, something that doesn’t bother me at all with 600mg of test/week for a year. I stopped because of the sides.
I haven’t seen people mention tren doesn’t bind to SHBG, whilst every other steroid only has 1-2% of its total mass active, as its not bound up by a protein. I would think a “microdose” of tren would be more like 5-10mg/day MAX, but those 40-60mg/day doses are great to start out on or cause a dramatic synergistic effect with other sterons, due to its profound ability to lower SHBG. Correct me if I’m wrong, I’m relatively ‘umderresearched’ in these areas
