A foundational androgen reference entry. FDA-Approved for Confirmed Hypogonadism. Schedule III Controlled Substance. WADA S1 Absolute Ban. TRAVERSE Trial (NEJM 2023): TRT Does Not Increase Cardiovascular Events in Hypogonadal Men. The TTrials: Sexual Function, Bone Density, Anemia All Improved. The Central Paradox: The Compound That Is Appropriate Medical Treatment at One Baseline Testosterone Level Is Misuse at Another. Aromatization, Estradiol Management, HPTA Suppression, Testicular Atrophy, Fertility, and the Full Monitoring Protocol.

Six Human Clinical Trials. 900+ Participants. Safety Indistinguishable From Placebo. Primary Fat Loss Endpoint Failed. WADA Banned. FDA Rejected for Compounding. The Community Uses It Anyway at Doses That Never Worked in the Trials.

The Pure Active Isomer in Clomid. The Drug That Raised Testosterone as Well as TRT While Preserving Fertility — and Still Failed FDA Approval. The Zuclomiphene Problem: Why the Racemic Mixture Causes Side Effects Pure Enclomiphene Shouldn't. The NDA That Died in 2021. How It Differs from TRT, HCG, and Gonadorelin for Male Hypogonadism. The 2025 Meta-Analysis: +273 ng/dL Testosterone vs Placebo.

The Nobel Prize Decapeptide (Schally and Guillemin, 1977). The Compound That Is Stimulatory When Pulsatile and Suppressive When Continuous — From the Same Receptor. The Most Pharmacologically Nuanced Chapter in this reference. Why the FDA's March 2020 HCG Compounding Ban Changed TRT Practice Overnight. Gonadorelin vs HCG: The Fertility Preservation Head-to-Head. Why FSH Matters for Spermatogenesis. The Pulsatile Dosing Problem in Practice.

FDA-Approved for Fertility and Male Hypogonadism. The Most Important Hormone in Post-Cycle Therapy. The Active Ingredient in the Simeons 500-Calorie Diet — a Fraud With Its Own FDA Warning. WADA S2 Banned. A Tumor Marker. Three Completely Different Identities in One Glycoprotein.

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.

40+ Years of Russian Research. 500+ Publications. One Institution. The Most Concentrated Single-Lab Provenance of Any Compound Class in this reference. Vladimir Khavinson (1946-2024) and the St. Petersburg Institute of Bioregulation and Gerontology. The Epigenetic Chromatin Mechanism. The Cytomax vs Cytogen Distinction. The 6-to-8-Year Mortality Study. The 2025 Independent Replication That Changed the Evidence Conversation. 14 Organ-Specific Bioregulators — Their Sequences, Targets, Evidence, and Protocols.

Named After Hershey's Kisses. Discovered as a Metastasis Suppressor Gene. Repurposed as the Master Upstream Regulator of the Entire HPG Axis. The Most Potent Known Activator of GnRH Neurons. Human Clinical Trials in Hypogonadotropic Hypogonadism, Hypothalamic Amenorrhea, IVF Triggering, and Hypoactive Sexual Desire Disorder. Limbic Brain Activation Proven by fMRI. No FDA Approval. The Most Pharmacologically Compelling Compound in PCT That No One Has Properly Studied for PCT.

Amino-acid-derived quaternary ammonium compound involved in mitochondrial fatty-acid transport. Commercial claims are often overstated, but specific forms have clinical evidence for neuropathy, peripheral artery disease, muscle recovery, male infertility, and post-MI cardiac outcomes.

The Most Phase-1-Tested SARM in History. The Problem: Phase 1 Used 0.1-1 mg. The Community Uses 5-20 mg. +1.21 kg Lean Mass at 1 mg in 21 Days. Phase 2 Hip Fracture Trial Positive. HPTA Suppression Dose-Dependent and Documented in Clinical Data. The Dose Gap Between Clinical Trials and Community Use Is the Central Risk Issue. Multiple Elite Athlete Doping Violations Including Canelo Álvarez. WADA S1.2.

Compounded MIC/B-12 lipotropic formulation that varies by pharmacy and is widely sold through weight-loss clinics. Evidence is strongest at the component level, especially inositol in PCOS/insulin resistance and injectable B12 for deficiency; weight-loss claims for the full blend remain weak.

The Most Clinically Studied SARM. The Phase 3 Trials That Nearly Got It Approved. Why the FDA Said No — and Why It Matters. The Most Modest HPTA Suppression Profile in the SARM Class. The Lowest Hepatotoxicity Signal. The Closest Any SARM Has Come to an FDA Indication. Why Phase 3 Failure Doesn't Mean the Compound Doesn't Work. Jonas Brodin and the NHL Doping Case.

The First Peptide Ever Synthesized (Nobel Prize 1955). FDA-Approved for Obstetric Use Since the 1950s. The 'Love Hormone' That Science Has Substantially Complicated. Intranasal Bioavailability ~2%. Trust Enhancement Replication Failures. Autism Trials: Mixed to Null. Context-Dependent Effects That Can Go Either Direction. And an OTC Nasal Spray Industry Built on Evidence That Doesn't Support What It Claims.

The Selectivity Claim That Doesn't Hold Up in the Only Published Human Trial. Phase 1 Breast Cancer Study: 59% Elevated AST, 45% Elevated ALT. Six or More Published DILI Case Reports — Including Near-Transplant Cholestatic Hepatitis. HPTA Suppression: As Real as Testosterone. WADA S1.2 Absolute Ban. FDA Warnings. The 53% Problem: Only Half of SARM Products Contain What They Claim. Why 'Fewer Side Effects Than Steroids' Doesn't Mean Safe.

Genuinely FDA-Approved for 18 Years. Withdrawn for Commercial Reasons, Not Safety. The Gateway Anti-Aging Peptide for a Decade of Compounding Medicine. Put on Category 2 in 2023. Apparently Returned to Category 1 Before the Broader 2026 Reclassification. The Cleanest Safety Profile of Any GH Secretagogue. The Somatostatin Feedback Ceiling That Makes It Physiologically Impossible to Overdose.

FDA-approved GHRH analog for HIV-associated lipodystrophy, used clinically to reduce visceral adipose tissue via pulsatile GH/IGF-1 signaling.
