OP, I'm running 150 test/150 deca/150 primo right now. I love the deca/test combination, at least how it makes me feel. It takes a while to see results, though, as these are long estered steroids. At about 8 weeks and probably feeling the effects the most now. Veins are bulging, arms/chest/back feel pumped. Haven't put on any weight though, I just feel much stronger and look better. I'm already at my max, though, and I would need to up my doses by a lot to put on any more size.

For hair - you have minoxidil, finasteride, microneedling, and biotin supplements. They work, I use them.
