man, i get the frustration, but dropping mast after only 5 weeks is a bit early—it usually starts shining right where you’re at, especially at 12% body fat. but if your heart is set on the "dark side" and you’re jumping into tren at 46, you gotta be smart about it. tren is a totally different beast than masteron.
since you’re already lean and just looking to polish off that cut, i wouldn’t go crazy. honestly, 200mg of tren ace a week (maybe 50mg every other day) is plenty to completely transform your look without making you feel like a paranoid insomniac. at our age, the night sweats and the "tren rage" can really wreck your quality of life and your relationships. keep that test at 250mg like you planned, but definitely keep an eye on your blood pressure and maybe some caber on hand just in case. tren is like magic for a cut, but it definitely demands respect or it’ll bite back hard! good luck with the switch!
