Understanding the CKF Risk Tier System
Not all peptides and research compounds carry the same level of uncertainty or potential risk. Some compounds have been extensively studied in humans and have decades of research behind them, while others remain highly experimental with limited safety data available.
To help readers quickly understand the relative level of uncertainty associated with a compound, CKF Tide Tables uses a simple four-tier risk classification system.
The purpose of this system is educational only. A lower-risk classification does not mean a compound is safe, while a higher-risk classification does not necessarily mean a compound is dangerous. Rather, the tiers reflect factors such as available research, duration of human use, known side effects, and overall scientific understanding.
Low Risk
Low-risk compounds generally have extensive human research, established clinical use, or a relatively well-understood safety profile. These compounds are typically among the most studied substances found within the peptide and metabolic research space.
Characteristics often include:
- Substantial human research data
- Well-documented side effect profiles
- Broad scientific understanding
- Longer history of use or investigation
Examples may include compounds such as Semaglutide, Tirzepatide, Melatonin, Glutathione, and L-Carnitine.
Moderate Risk
Moderate-risk compounds generally possess a reasonable amount of supporting research but may have more limited long-term safety data, fewer human studies, or greater uncertainty regarding optimal use.
Characteristics often include:
- Moderate human research availability
- Some unanswered safety questions
- Less extensive long-term data
- Growing but incomplete scientific understanding
Examples may include compounds such as BPC-157, TB-500, CJC-1295 No DAC, Ipamorelin, and NAD+.
High Risk
High-risk compounds often have limited human research, significant unanswered safety questions, or mechanisms that may carry greater potential for unintended effects.
Characteristics often include:
- Limited human data
- Poorly understood long-term effects
- Greater uncertainty regarding safety
- Potential for significant physiological impact
Examples may include compounds such as Retatrutide, Mazdutide, Gonadorelin, PT-141, and Tesofensine.
Experimental / Danger Tier
Experimental / Danger Tier compounds represent the highest level of uncertainty within the CKF system. These substances often have very limited human research, highly experimental mechanisms, or safety concerns that remain poorly understood.
Characteristics often include:
- Very limited human research
- Novel or poorly understood mechanisms
- Significant unanswered safety questions
- Potential for serious unintended consequences
These compounds should be viewed as highly experimental and are often discussed primarily from a research perspective rather than a practical application perspective.
Examples may include compounds such as ACE-031, Adipotide, and certain emerging investigational agents.
Important Notes
- Risk tiers are educational classifications and not medical advice.
- A lower-risk classification does not guarantee safety.
- A higher-risk classification does not necessarily indicate known harm.
- Scientific understanding evolves over time and risk classifications may change as new research becomes available.
- Individual compounds should always be evaluated on their own merits and limitations.
Final Thoughts
The CKF Risk Tier System is intended to provide readers with a quick reference point when exploring Tide Tables. It should be viewed as a tool for understanding relative levels of uncertainty rather than a definitive measure of safety.
Whenever possible, readers are encouraged to review original scientific literature and consider the quality and quantity of available evidence before drawing conclusions about any compound.
