- Collagen Peptides (Hydrolyzed Collagen)
- Fibroblast activation, Type I/III collagen synthesis upregulation
- Tendons, ligaments, cartilage, fascial tissue
- 10–20g within 60 minutes post-training, with 50mg vitamin C to enhance hydroxylation
- American Journal of Clinical Nutrition (2017): 20% reduction in muscle soreness, 18% reduction in creatine kinase at 24 hours
- Best for connective tissue recovery. Plyometrics, downhill running, eccentric-heavy work. Minimal effect on muscle fiber hypertrophy.
- Growth Hormone Secretagogues (CJC-1295, Ipamorelin)
- Pituitary GH release → hepatic IGF-1 production → mTOR pathway activation in muscle cells
- Skeletal muscle fibers, satellite cells
- CJC-1295: 100–200mcg subcutaneous 2–3x/week; Ipamorelin: 200–300mcg post-workout
- Journal of Clinical Endocrinology (2012): 1.8kg lean mass increase over 8 weeks, sustained IGF-1 elevation for 6–10 days
- Best for muscle hypertrophy and protein synthesis. Requires subcutaneous administration. No effect on tendon repair.
- BPC-157 (Pentadecapeptide)
- Angiogenesis promotion, VEGF upregulation, nitric oxide pathway modulation
- Muscle fibers, tendons, ligaments, gastric mucosa
- 250–500mcg subcutaneous or oral, daily for 2–4 weeks
- Preclinical models only (rodent tendon healing studies). No human RCTs published as of 2026
- Promising preclinical data but lacks Phase 3 human evidence. Used off-label in research contexts. Legal status varies by jurisdiction.
- MK 677 (Ibutamoren)
- Ghrelin receptor agonism, sustained GH/IGF-1 elevation
- Skeletal muscle, bone density, metabolic rate
- 12.5–25mg oral, once daily (not a peptide but a growth hormone secretagogue mimetic)
- Annals of Internal Medicine (2008): 1.1kg lean mass gain over 2 months in elderly adults
- Oral bioavailability advantage over injectable peptides. Long half-life (24 hours). Appetite stimulation as side effect.
