- The table below compares three common stacking protocols used in tissue repair research, evaluated on dosing structure, injection frequency, and typical application contexts.
- Conservative Stack
- 1.5mg every other day (MWF)
- 2mg twice weekly (Mon/Thu)
- 5 total injections
- Chronic low-grade tissue repair, preventive anti-aging models, collagen maintenance in aged subjects
- Lowest risk of receptor saturation; best for long-term protocols (12+ weeks); minimizes peptide cost while maintaining efficacy for non-acute conditions
- Standard Stack
- 2mg three times weekly (MWF)
- 2.5mg twice weekly (Mon/Thu)
- Acute soft tissue injury, post-surgical healing, tendon/ligament repair models
- Most commonly cited in observational research; balances tissue-level saturation with cost; suitable for 6–8 week loading phases
- Aggressive Stack
- 3mg daily
- 5mg twice weekly (Mon/Thu)
- 9 total injections
- Severe chronic wounds (diabetic ulcers, radiation-damaged tissue), acute traumatic injury with compromised vasculature
- Highest peptide exposure; risk of diminishing returns after week 4; requires strict injection site rotation and monitoring for off-target effects; typically reserved for cases where monotherapy has failed
- The Standard Stack represents the most evidence-supported protocol for general tissue repair research. The Conservative Stack extends protocol duration while reducing cost per week by approximately 40%, making it viable for studies with budget constraints or long observation periods. The Aggressive Stack should be reserved for acute high-severity models where tissue damage exceeds the repair capacity that moderate dosing can address. It is not a default choice for routine injury models.
