- Conservative rest + nutrition
- Removes mechanical stress; supports endogenous repair with adequate calcium (1200mg/day), vitamin D (2000–4000 IU/day), protein (1.6g/kg body weight)
- 6–12 weeks depending on fracture grade and location
- No hormonal optimization; relies entirely on baseline metabolic health
- Gold standard—everything else is adjunctive to this foundation
- MK-677 (25mg daily)
- Elevates growth hormone and IGF-1; increases osteoblast activity and collagen synthesis systemically
- Potentially 6–10 weeks with disciplined load management
- Doesn't override mechanical constraints; side effects include water retention and glucose elevation
- Reasonable adjunct if baseline IGF-1 is suboptimal; not a standalone solution
- BPC-157 (250–500mcg daily, subcutaneous near injury)
- Promotes angiogenesis and collagen organization at local tissue sites; may enhance soft tissue-to-bone interface healing
- 4–8 weeks for soft callus phase; less evidence for cortical bone specifically
- Limited human RCT data; most evidence is preclinical or anecdotal
- Strongest case for tendon-bone junction injuries; weaker for isolated cortical stress fractures
- Calcium + Vitamin D supplementation
- Ensures adequate substrate availability for mineralization; corrects deficiency states common in stress fracture populations
- No direct effect on timeline—prevents delayed healing
- Only effective if baseline deficiency exists; excess provides no added benefit
- Non-negotiable baseline; test serum 25(OH)D before assuming adequacy
