OvagenvsCartalax

Molecular Formula

C₁₅H₂₅N₃O₈

Molecular Weight

375.4 g/mol

Half-Life

Short plasma half-life typical of tripeptides; biological effects persist for weeks through epigenetic modifications to hepatic gene expression; metabolized to constituent amino acids (glutamic acid, aspartic acid, leucine)

Bioavailability

Effective via oral capsule (10 mg twice daily), sublingual liquid (0.1 mg/mL), and subcutaneous injection routes; penetrates cell membranes and nuclear membranes as a cell-penetrating peptide; tissue-specific activity demonstrated in organotypic hepatic cultures at 10⁻⁶ to 10⁻⁹ M

CAS Number

Not assigned (proprietary Khavinson peptide)

Molecular Formula

C₁₂H₁₉N₃O₈

Molecular Weight

333.3 g/mol

Half-Life

Short plasma half-life typical of tripeptides (minutes to hours); biological effects persist for weeks to months through epigenetic gene regulation; metabolized to constituent amino acids

Bioavailability

Orally bioavailable via intestinal peptide transporters (PepT1/PepT2, LAT1); 10-fold more potent than crude cartilage polypeptide complex at chondrogenic activation (200 vs 2000 ng/mL effective concentration)

Safety Overview

Ovagen demonstrates favorable safety in reproductive endocrinology applications with no serious adverse events reported in clinical ovulation induction studies. As a kisspeptin analog, primary safety consideration is ovarian hyperstimulation syndrome (OHSS) risk, requiring careful hormone monitoring and patient education on abdominal pain, bloating, and nausea symptoms. Mild headaches and injection site reactions occur in <10% of users. Reproductive safety in animal models shows normal fetal development with no teratogenicity.

Contraindications

• xKnown hypersensitivity to peptide bioregulators or constituent amino acids (glutamic acid, aspartic acid, leucine)
• xPregnancy and breastfeeding — insufficient reproductive safety data
• xSevere glutamic acid metabolism disorders (extremely rare)
• xActive autoimmune hepatitis in flare without physician supervision

Evidence Level

Moderate human trials (Phase 1-2)

FDA Status

Research compound

Safety Overview

Cartalax (polypeptide complex from bovine cartilage) has not undergone formal FDA approval or rigorous clinical safety trials. The safety profile is based on traditional use in Russia and Eastern Europe as a cartilage extract supplement, with limited published safety data. As a complex mixture of polypeptides, collagens, and proteoglycans, the actual active components and their pharmacology are undefined, making toxicity prediction impossible. Potential allergic reactions to bovine proteins exist, and contamination risks from source animal tissues cannot be ruled out without pharmaceutical manufacturing standards.

Contraindications

• xKnown hypersensitivity to peptide bioregulators or constituent amino acids (alanine, glutamic acid, aspartic acid)
• xPregnancy and breastfeeding — insufficient reproductive safety data
• xActive joint infection — treat infection before initiating peptide bioregulator therapy
• xMalignant bone or cartilage tumors — proliferative effects of peptide bioregulators may be contraindicated
