Insulin 100% never for me unless i was diabetic. I have a couple buddies that compete and they use it and are ripped to shreds but the amount of other shit they are taking plus their dedication and diet it works for them. The other 99% of bodybuilders shouldnt need it.
Tren it just doesnt really appeal to me? I hate when I feel winded as I push myself to the max on cardio I like feeling like im able to go and do whatever without worrying about tiring out. Huffing and puffing going up a flight of stairs, tren cough, etc has no appeal to me but its an awesome compound if you want crazy results. Just not for me.
Dude especially with having to wear a mask in the gym now, could you imagine a run on tren while trying to breath and wear one of those the whole time , hell no. And I just dont like nasty toxic compounds, I hate feeling paranoid and tren would make me feel that way with all the nasty shit I've read and seen people talk about.
