Derived from gastric juice protein. Builds new blood vessels into damaged tissue locally. 100+ animal/cell studies (tendon, gut, muscle, bone, nerve).\nTB-500 — Synthetic Thymosin Beta-4. Moves repair cells to damage; clears stuck inflammation systemically. Production drops ~60% by age 60.\nARA-290 — Nerve repair peptide with human clinical trial data. Regrows damaged nerves; does not mask nerve pain.\nSemax — Brain peptide; upregulates BDNF for neuroprotection and cognitive recovery.\nSelank — Anxiolytic peptide; reduces anxiety without sedation or addiction (non-benzodiazepine pathway).\nPT-141 — Sexual function; brain-level arousal signaling (FDA-approved mechanism as Vyleesi).\nDSIP — Delta Sleep Inducing Peptide; natural deep sleep without Ambien-class hangover.\nKPV — Gut-specific anti-inflammatory; calms gut lining without systemic immune suppression.\nGHK-Cu — Tissue remodeling; builds collagen scaffolding.
