Peptides, TRT & What Most Clinics Won’t Tell You


In this episode of the Flex Diet Podcast, I sit down with my good friend John Gorman to unpack the current “wild west” of peptides, TRT, GLP medications, and performance-driven bloodwork.

We dig into how John’s telemedicine clinic approaches comprehensive lab testing — and why running a full panel (including markers like reverse T3) matters far more than cherry-picking a few numbers.

If you’ve been dieting hard, training consistently, and still feeling stuck, we break down how chronic stress, poor recovery, and subtle hormone disruptions can quietly crush metabolism and make fat loss feel like a white-knuckle grind.

We also cover testosterone replacement therapy (TRT) — the real pros and cons, common oversimplifications in the industry, and what most clinics fail to discuss.

From there, we dive into GLP-1 medications and tirzepatide, what we currently know, what we don’t know about long-term use, and how to think critically about risk versus reward.

John shares practical guidance on legitimate peptide sourcing, red flags to watch for, and how to think about “periphery” tools like methylene blue and injectable carnitine without getting sucked into hype.

If you’re interested in optimizing performance, improving body composition, or simply making smarter decisions in a rapidly changing medical landscape, this episode will help you separate signal from noise.

The fitness internet has the attention span of a caffeinated squirrel with a crypto account full of DOGE coin. A study drops with a huge number and some IG GooRoo between ab shotz and posing in front of his rented fancy car rips that number out of context, sprays it across social media like cheap cologne in a strip mall bathroom, and suddenly every shirtless man with a ring light is telling you the sauna is basically anabolic sorcery. Then the supplement companies arrive followed fast by the...

Aaaah, my buddy Joe Rogan. I will get hate for this but overall I love Joe and his show most of the time… …however, the practice of going ballZ deep at 33F in the ice bath as a recommendation to start is bonkers. This has also spun off a whole slew of “Cold Water BroZ” via the cult of Joe with their own epic posting about their love of cold water immersion after lifting ‘cuz "recovery, bro." Can doing cold water immersion (CWI) immediately after lifting stall your gainZ? Here's what's...

Newsflash Brosefus, your body does not want to add more muscle, run faster, and get leaner all by itself. This is not a motivational failure nor a mindset problem where you just need to biohack your way out or keep trying harder. This is physiology at its most fundamental as your body is designed to survive above everything. A massive part of this survival mechanism is homeostasis, your body's insane, around-the-clock commitment to holding its internal environment constant no matter what you...
