It's preferred over tren by most who don't want to deal with tren sides. Tren is a shit drug from a side effect standpoint. I love the results but hate everything that comes with it. I've been thinking about mast as a substitute. Currently decided to just stick to test only.
I personally love mast. It gives me an edge in the gym and I feel I have more aggression during difficult sets. It really doesn't "pack on the mass" but given a proper caloric surplus, it could certainly help.
If you're dieting, it's a great compound to help retain lbm whilst shedding body fat. Overall, I think it's great.
Yeah exactly. Mast complimenting tren doesn't mean it can replace it. If you use ace, try pinning it every day instead of every other day. Seems like a minor change but it really makes a huge difference on sides. Use a 29g slin pin if you're worried about scar tissue
