The first randomized trial of resistance training on tirzepatide is here.
Researchers in Western Australia put 120 adults between 50 and 70 on tirzepatide for 40 weeks.
Half of them lifted weights three times a week, and the other half went about their normal lives. At the end, both groups had lost almost exactly the same amount of weight, roughly 22 kilograms each.
The group that lifted lost 25% less lean tissue.
Their strength went up 10 to 18%. The group that didnβt lift got 6 to 9% weaker over the same stretch.
To be fair, lifting reduced lean loss but didnβt eliminate it. The training was supervised, attendance was 91%, and most people wonβt hit that on their own.
At the end of the day, Tirzepatide is a remarkable tool for taking fat off the body. However, a tool only does what it was built to do, and protecting your muscle was never its job.
That part falls on you!
Three days a week under a bar. Consider it part of the prescription.
Your pituitary made about 2 IU of growth hormone a day at 25. By 60 you are down to roughly a quarter of that.
Peptides push the system for a while. Eventually all roads lead to HGH.

Perimenopausal women are getting put on GLPs before anyone checks their hormones.
Then it "doesn't work." Or they drop 10 pounds in two weeks and can't walk up the stairs.
The GLP usually isn't the problem. The body isn't ready for it.
Get the hormones checked first. Get the blood work in a better place. A lot of the time the weight starts coming off before a GLP ever enters the picture.
When it does make sense, newest isn't always best. Everyone wants reta. Tirzepatide is often the better place to start, and you can always move up.
Half a pound to a pound a week is a great pace. It feels slow. Do the math over a year.
And a GLP doesn't replace the work. It raises the stakes on it. Lift heavy. Eat enough protein. Stop starving yourself and then wondering why it stopped working.
Stephanie Gambetta breaks it all down here.
Are COA's a cottage industry to give people warm, fuzzy feelings?
The vial that got tested isn't the vial you're injecting.
I get why they exist. I think they're probably even necessary. They're just way overemphasized.
Here's what I actually trust instead.
A lot of people blame glucagon for the heart rate bump on reta.
That's definitely true.... BUT, Mazdutide hits glucagon too, but the numbers I've seen look a lot closer to tirzepatide.
Taylor and I have been testing it. Here's what we're finding, and who it might actually be for.
I was wrong about retatrutide.
I used to think it beat tirzepatide in almost every case.
It's still the king of fat loss. But I'm now seeing people do worse on it, especially women in their 40s and 50s.
Here's who it backfires on.
Most people think DSIP is just a sleep peptide.
A 2003 study showed it cut tumor incidence 2.6 fold and extended maximum lifespan by 24% in mice.

Most people take DSIP expecting a peptide version of Ambien. That is why they write it off.
