Episode notes

Why Retatrutide Could Become The Ferrari Of GLP 1s

  • Retatrutide is presented as the next major obesity drug because it activates three receptors, adding glucagon to GLP-1 and GIP.
  • Alex Tatem says trials and underground use show dramatic weight loss plus unusually strong liver-fat improvements.

Growth Hormone Peptides Have Real Upsides And Real Risks

  • Growth-hormone peptides may improve recovery, sleep, body composition, and skin, but they are easy to oversell and easy to abuse.
  • Alex Tatem warns excess growth hormone can drive insulin resistance, numb hands, acromegaly, and possibly worsen existing cancer.

Avoid Research Only Peptides And Work With A Doctor

  • Avoid research-only peptides and use a doctor to match legal options to your actual problem.
  • Alex Tatem says patients should educate themselves, then discuss symptoms with a physician instead of buying unverified vials online.
