Serine (Ser) is a non-essential AA that can be generated from the Glycolysis intermediate 3-phosphoGlycerate (3-PG) through the de novo Serine Synthesis Pathway (SSP) by the sequential action of three enzymes PhosphoGlycerate Dehydrogenase (PHGDH), PhosphoSerine Aminotransferase (PSAT1), and PhosphoSerine Phosphatase (PSPH) [13], or it can be obtained by glycine (Gly) through the Serine hydroxymethyl-transferase (SHMT) [14]

Unlock the Science Ingredient How it Works Accelerates healing of muscles, tendons, ligaments, and joints by upregulating growth factors Repairs the gut lining and reduces GI inflammation, supporting digestive health and leaky gut Stimulates angiogenesis and nerve regeneration to restore function at injury sites Reduces systemic inflammation to improve mobility, comfort, and overall recovery speed Protects and repairs the gastrointestinal tract, including ulcers and inflammatory conditions Drug Facts Peptide therapies are not FDA-approved for anti-aging but are commonly prescribed off-label in regenerative and hormone optimization clinics

Storage and handling Maintain peptide quality: Store reconstituted peptides refrigerated (2-8C) Use within 28-30 days after mixing Keep lyophilized powder cool and dark Never freeze after reconstitution Proper reconstitution: Use bacteriostatic water (not sterile water for long-term use) Follow exact ratios Mix gently (don't shake) Calculate doses precisely Use our peptide reconstitution calculator , free peptide reconstitution calculator , and how long reconstituted peptides last in fridge guide
