Healing & Recovery

544 Papers, 30 Years, One Lab — The Healing Peptide with the Most Research and the Least Independent Evidence

The Body's Own Repair Signal — And the Evidence Gap Between What It Does and How People Use It

Discovered by Immunologists, Repurposed by Horse Trainers, and Now It May Be a Prodrug

Alpha-MSH's Anti-Inflammatory Fragment — And It May Work Completely Differently Than Everyone Thinks

Engineered EPO-derived tissue-protective peptide that activates innate repair signaling without erythropoietic red-blood-cell stimulation. Human neuropathy data exist; WADA bans it under EPO-related peptide/mimetic rules; the original developer no longer exists.

More Clinical Trial Data Than Almost Anything in this reference. Approved in Over 40 Countries. The Largest Independent RCT Failed Its Primary Endpoint. Every Major Positive Trial Has the Manufacturer's Name in the Author List. Cochrane Says: Low to Very Low Evidence.

The Only Senolytic With Real Human Trial Data. Tested at the Mayo Clinic. Proven to Clear Senescent Cells in Humans. Dasatinib Is a Chemotherapy Drug. The Community Is Using It Without Prescriptions, ECGs, or Drug Interaction Screens.

NOTE: This chapter covers GHK as a free tripeptide — its endogenous biology, copper-carrier function, and primary topical cosmetic applications. The systemic, injectable, and regenerative applications of the copper-chelated complex are covered in the GHK-Cu chapter, which should be read alongside or before this chapter. Plasma Levels: 200 ng/mL at Age 20, Declining to 80 ng/mL by Age 60. The Connectivity Map and 4,000 Genes. Loren Pickart (1938–2023). The Copper Switch.

GLOW Stack is the Wolverine Stack with GHK-Cu added

Scope appropriateness is the question: local gut peptides are being stacked for barrier integrity and inflammatory signaling, not for systemic regeneration claims.

The Compound Every Secretagogue in this reference Targets. 191 Amino Acids. FDA-Approved for GH Deficiency, HIV Wasting, Short Bowel Syndrome. July 2025: Skytrofa Once-Weekly Now Approved for Adults. The Pulsatile vs Continuous GH Exposure Distinction. IGF-1 as the Surrogate Marker. The Fake HGH Crisis. WADA S2 Absolute Ban. Why Secretagogues (Sermorelin, Ipamorelin, MK-677) Are Different. The Active Malignancy Hard Stop. The Cancer-IGF-1 Question That Never Goes Away.

Designed as a Research Tool to Bypass IGFBP Regulation. ~100-Fold Reduced Binding-Protein Affinity. 20-30 Hour Half-Life vs IGF-1's 10-15 Minutes. The Most Potent IGF-1 Analog Available. No Controlled Human Trial for Body Composition. No Tumor Selectivity. WADA S2 Banned. A Compound Whose Full Cancer Risk Is Genuinely Unknown.

Adds KPV’s local gut anti-inflammatory signal to the GLOW recovery-and-skin stack.

The Only Human Cathelicidin. Antimicrobial, Anti-Biofilm, Pro-Angiogenic, Immunomodulatory, Wound-Healing. Phase IIb Clinical Evidence in Chronic Wounds. Overexpressed in Rosacea, Ovarian Cancer, Breast Cancer, Lung Cancer, Melanoma. Tumor-Suppressive in Colon and Gastric Cancer. The Most Contextually Bidirectional Compound in this reference. Vitamin D Is Its Most Important Natural Inducer.

The Drug That Was Going to Treat Leaky Gut and Celiac Disease — And How the Phase 3 Trial Ended. What Zonulin Actually Is and Why Tight Junction Regulation Is Hard to Measure. Four Phase 2 RCTs: Symptom Improvement With Gluten Challenge. The Phase 3 Discontinuation in 2022. The N-Acetyl Modification That Limitless Sells: What It Adds and What It Doesn’t Change. How This Differs From BPC-157 and KPV in the Gut Stack.

FDA-Approved at 50 mg for Opioid and Alcohol Use Disorder Since 1984. Off-Label at 1.5-4.5 mg (LDN) — Two Completely Different Mechanisms at Two Completely Different Doses. TLR4 Blockade on Microglia. The Endorphin Rebound. A Lancet Rheumatology RCT in 2024. An Evidence Base Growing Faster Than Pharma Has Any Reason to Fund. The Most Favorably Tolerated Prescription Drug in Its Evidence Literature.

The Fragment Every Community Vendor Sells as ‘TB-500.’ The Actin-Sequestering Domain of Thymosin Beta-4. Why the Full 43-AA Protein Is Used in Clinical Trials While the Community Uses a 7-AA Fragment. The Phase 2b Cardiac Trial That Used Full Tβ4. Whether the Fragment Recapitulates the Parent Protein’s Pharmacology. What Actin Sequestration Actually Does in Tissue Repair. Polaris and Limitless Community Formats.

Approved in 37+ Countries. The Most Extensively Studied Thymic Peptide in Clinical Medicine. 30+ RCTs. 11,000+ Subjects. HBeAg Seroconversion RR 2.31. A Positive Sepsis Trial in 2013 Followed by a Definitive Negative Phase 3 in 2025. The US Regulatory Rollercoaster: Category 2 (2023) → Nomination Withdrawn (2024) → Pending PCAC Review (2026). Immunomodulator, Not Immunostimulant — A Critical Distinction.
