Classic examples include native GLP-1, which has a plasma half-life of approximately 2 minutes and required continuous infusion in early studiesan impractical route for chronic therapyyet was subsequently transformed into a once-weekly therapeutic through lipidation and albumin-binding strategies ( Third, pleiotropic signaling that aligns with physiological function rather than nonspecific toxicity favors re-evaluation
Despite these findings, a clear link has yet to be established, and much of the evidence remains inconsistent
I also measure the signaling hormones TSH, LH & FSH, as well as things that can inhibit normal signaling, like estradiol, prolactin, inflammation, blood sugar, growth hormone, and micronutrient deficiencies
