Summary
Is GLP-3s the Next Evolution in Peptides? Here's What You're Not Hearing
Everyone's obsessed with GLP-1s like GLP-1. But what if there's a better option with more benefits, fewer side effects, and real potential for body recomposition, brain health, and gut repair? It's called GLP-3 peptides, also known as Retatrutide, and most people haven't even heard of it yet.
In this episode, I break down why GLP-1s aren't the miracle drugs people think they are. They suppress appetite, yes, but at the cost of muscle mass, nutrient absorption, and long-term metabolic health. GLP-3s work differently. It improves gut integrity, boosts BDNF for brain performance, enhances metabolic flexibility, and reduces inflammation at the root.
I also walk through how I use GLP-3s in client protocols, from microdosing to blood work analysis, and how it fits into a serious longevity strategy. If you care about more than just weight loss, this is the peptide you need to understand.
Listen to the full breakdown. This one matters.
We Also Discuss:
(00:04) Why GLP-3s are the peptide nobody's talking about, yet
(03:52) What is GLP-3s and how it differs from GLP-1
(07:22) Gut health and healing leaky gut with GLP-3s
(10:46) Brain health, BDNF, and cognitive benefits
(20:35) GLP-3s for longevity, inflammation, and full-body optimization
(24:00) Final thoughts, client protocols, and how to get started with GLP-3s

| 0:44.8 | I'm a hybrid athlete, a natural pro bodybuilder, and I've competed in events such as Ironman |
| 0:50.1 | Triathlon, Ultramarathon, Spartan, and many more. My goal with this podcast is to cut through |
| 0:56.7 | the noise of fitness myth, misconceptions, and deliver clear protocols, actual tips, and real |
| 1:04.1 | resilience and science to help you optimize your physique, elevate your physical and mental |

| 1:15.2 | Well, hello, everybody. |
| 1:17.4 | Chris Gethin here. |
| 1:18.8 | Welcome to the podcast. |
| 1:20.9 | And today, the title of this podcast is going to be GLP's and five reasons why more people should be talking about this |
| 1:30.2 | peptide. And in today's episode, this is one that I've really been looking forward to because |
| 1:35.5 | we're covering a peptide that hardly anybody is really talking about yet, especially in the mainstream, |
| 1:41.0 | but I've had many clients on this peptide over the years, but I think it could |
| 1:45.5 | play a major role in the next generation of longevity protocols and peptides. It's called GLP3, |
| 1:53.5 | or otherwise known as retitutide. And it may offer a lot of metabolic and health benefits that |
| 2:00.7 | people are chasing with GLP-1s like |
