- Collagen Peptides
- Fibroblast stimulation via dipeptide signaling; increases procollagen type I expression
- Strong (8+ RCTs, 1,000+ participants)
- 10–15g oral daily
- Skin markers improve at 4–8 weeks; joint effects at 12–24 weeks
- Best-supported option for connective tissue repair; safe during lactation; bioavailable oral delivery
- BPC-157
- VEGF upregulation; accelerates angiogenesis and epithelial migration
- Moderate (animal models only; no human RCTs)
- 200–500mcg/kg subcutaneous in animal studies
- Wound healing effects within 7–14 days in rodent models
- Promising preclinical data but zero human postpartum trials; legal status varies by region
- Thymosin Beta-4 (TB-4)
- Actin sequestration; promotes cell migration and angiogenesis
- Moderate (Phase I/II human safety data; no postpartum trials)
- 5–10mg subcutaneous weekly in cardiac trials
- Cardiac function improvement at 4 weeks in MI patients
- Mechanistically plausible for tissue repair; human data exists but not in postpartum population
- Thymalin
- T-cell maturation; shifts Th2-dominant state toward balanced Th1/Th2
- Weak (small trials in autoimmune populations; no postpartum-specific research)
- 5–10mg intramuscular 2–3x weekly
- Immune markers normalize over 4–8 weeks in limited trials
- Theoretical benefit for immune recalibration; minimal human data; not commercially available in most regions
- GHK-Cu (Copper Peptide)
- Stimulates collagen and glycosaminoglycan synthesis; modulates metalloproteinase activity
- Moderate (dermatology trials; no postpartum-specific research)
- 1–3% topical or 1–2mg subcutaneous
- Skin remodeling visible at 4–12 weeks
- Established in wound healing and skin rejuvenation; oral bioavailability poor; topical or injectable only
