How to Build Muscle After 45 When Gear Alone Isn't Working

The fastest way to put on mass if you're over 45 or any age, for that matter, is to, number one, go into the gym and lift like a fucking animal, okay? Bring every set to failure, push yourself beyond the scope of what you believe you're capable of, train with a high degree of intensity that should feel painful, okay? And then when you do that consistently, you should be sore and hungry.

That soreness and that hunger are not side effects, they are the readout, the signal that tells you the stimulus was big enough that your body now has to respond to it.

Muscle growth begins with a mechanical signal, the kind that only shows up once you load a fiber hard enough and close enough to failure that the tissue registers real stress. That stress turns on a signaling pathway called mTOR, which is the switch that tells a muscle cell to start assembling new protein. The switch does not care what's in your bloodstream if nothing flipped it.

Hard training creates the signal, food supplies the raw material and the surplus energy to build with, sleep and rest give the body the window to actually do the construction, and hormones raise the ceiling on how much of all that gets turned into tissue. That's the full chain, four links, and gear is only the fourth one.

The part most guys skip is the least fun part. In order for you to put on meaningful amounts of muscle and in a bulk, you should be eating so much food that it's literally uncomfortable to eat.

For all the people who understand what it feels like to build muscle in bulk, you know that bulking is way fucking harder than cutting, because the discomfort that you have to live with while you're eating that much food is unbearable.

There is a reason this gets harder after 45. Older muscle responds less to a given dose of protein than young muscle does, something researchers call anabolic resistance, where the same meal produces a smaller rise in muscle protein synthesis. Wall and colleagues showed that older men needed a larger protein feeding than younger men to get the same muscle building response.

The practical version is that the portion size that worked for you at 30 is undershooting at 50, and you will not feel the difference. You will just stall and blame the cycle.

Once you have those two things locked in and you're consistent with your recovery, your rest, your sleeping, and you're staying consistent with that, then you can talk about the compounds that you're taking, right, you know, test, DECA, TRAN, if you want, at a low dose, I would go TRAN-E. Add up to four to six IUs of growth.

And even there, growth hormone is doing something different than most people assume. It drives collagen and connective tissue turnover and fluid retention far more than it drives contractile muscle fiber on its own, which is why the scale moves and the mirror doesn't.

The reason more gear stops working is that none of it manufactures a stimulus. Androgens increase how efficiently you convert training and food into tissue. If the training is submaximal and the food is short, you are multiplying a small number by a bigger coefficient, and a small number times three is still a small number.

Yes, you can add the anabolic, yes, you can add more GH, but if the way that you train, if the way that you lift, if the way that you eat don't support the long-term goal, and I've had this conversation numerous times with people and you guys don't want this answer, but I'm telling you, you will not see the result by just simply adding more gear.
