At a Glance Dose Range Apelin-13 As prescribed–As prescribed mg BPC-157 250–500 mcg Frequency Once daily Administration Intravenous (IV) Subcutaneous injection Cycle Length Ongoing/indefinite 4-6 weeks Onset Speed Moderate (1-2 weeks) Evidence Level Moderate human trials (Phase 1-2) Strong preclinical (extensive animal studies) Efficacy Cardiovascular Support Heart Function & Strength Blood Flow & Circulation Primary Benefit Secondary Benefit Additional Benefit Technical Data Molecular Formula C69H111N23O16S Molecular Weight 1550.8 Da Half-Life Minutes in plasma; varies by route of administration Bioavailability ~90-95% (subcutaneous injection) CAS Number Not yet assigned (research compound) C62H98N16O22 1419.53 g/mol 4-6 hours ~100% (subcutaneous) 137525-51-0 Protocols starting 30 nmol/min Continuous infusion 5 minutes per dose step (research setting) Apelin-13 is a research peptide given as a short drip into a vein in studies, not by self-injection. This low rate was the first step tested in a human heart study. [4] standard 100 nmol/min Middle infusion rate used in the human heart study. It increased the heart's output and relaxed blood vessels. [4] advanced 300 nmol/min Highest infusion rate tested in the same human study, producing the strongest effect on heart output and blood pressure. [4] 250 mcg 1-2 weeks A common starting amount in research practice, often injected near the injured area. BPC-157 has no human dose-finding trials, so doses come from animal studies and documented practice [1][2]. 250-500 mcg Twice daily Commonly used range for tissue and tendon recovery in research practice [1][3]. 500 mcg 6-8 weeks Upper end used in practice for more demanding acute injuries [1][3].

Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach. Tendon and ligament injuries Sprains, strains, tears, tendinitis - BPC-157 accelerates collagen synthesis and tissue repair Gut healing IBS, leaky gut, ulcers, inflammatory bowel conditions - derived from gastric juice, it has a natural affinity for digestive tissue Muscle injuries Strains, post-workout recovery, chronic muscle issues - promotes angiogenesis and growth factor expression Joint problems Arthritis support, joint pain, cartilage issues - anti-inflammatory and regenerative properties Post-surgical recovery Accelerating healing after procedures - works systemically to enhance the body's repair mechanisms Safety Profile Common Mild changes in blood pressure Minimal systemic effects in animal studies Headache (theoretical, based on blood pressure effects) Flushing or warmth at injection site Mild inflammation at injection site Dizziness if blood pressure drops too quickly Allergic reactions to the peptide Heart rhythm changes (requires monitoring) Blood pressure, heart rate, cardiac function Serious Severe allergic reaction Injection site redness Mild nausea Dizziness Uncommon Headache Fatigue Hot/cold sensations Allergic reaction Research Status FDA Status Research compound Safety Overview Apelin-13 is a research compound with no human clinical trials or FDA approval. All safety data comes from animal studies and in vitro mechanistic work showing beneficial effects on vascular function and cardiac remodeling. However, animal models do not predict human safety, and the peptide's effects on immune regulation in humans remain untested. No dose-ranging studies, pharmacokinetics, or organ accumulation data exist in humans. The APJ receptor is expressed in multiple tissues including brain, raising concerns about off-target neurological effects at high doses. Contraindications xCurrently under investigation - not for human clinical use xMay interact with blood pressure medications (in theory) xShould not be used if allergic to peptides or component amino acids xPregnant or breastfeeding individuals should avoid BPC-157 is a gastric pentadecapeptide with strong preclinical evidence from extensive animal studies spanning over 25 years of research. Critical limitation: BPC-157 has NOT completed Phase 3 human clinical trials. No FDA approval exists. Safety data comes primarily from rat and mouse studies, with only limited Phase 1-2 human data. Animal studies show no toxicity at therapeutic doses, but human data is insufficient for regulatory approval. The peptide is unregulated, and no standardized manufacturing or quality control requirements exist for research compounds. Individual responses may vary significantly, and serious medical supervision is essential before use, particularly if you have gastrointestinal conditions, take medications, or have pre-existing medical conditions. xPregnancy xBreastfeeding xActive cancer xHistory of cancer Decision Guide Choose Apelin-13 if...
