Testosterone is a good one for bulking. It will boost your appetite. But if you're not eating a proper diet and training, you're not gonna get the results you are looking for.
methyltrienolone-1 Is a very strong product. It's highly potent and highly anabolic. If you're serious about bodybuilding, it's one to take a close look at.
Make sure you're using trenbolone at 50mg a day or every other day, and I would go with trenbolone acetate. I would use n2guard with it. If you stack testosterone, you may need an AI.
I would do some tbol and anavar, 20 milligrams of each, or a cool stack would be tbol and dianabol. They both would work together good with testosterone.
