Testosterone Cypionate's 3/10 rating is in our caution tier. Either documented side-effect patterns are concerning, the human safety dataset is too thin to make confident statements, or the compound is under active regulatory scrutiny. We recommend reviewing the full notes above and consulting a licensed physician before any research use.

Methodology

How we rate peptide safety

Every compound in our index gets a 1–10 safety score based on four weighted factors. The score reflects known research-use risk — not medical advice.

40% — Clinical evidence. Volume of peer-reviewed trials, sample sizes, duration, and consistency of outcomes. FDA-approved compounds anchor the top end (8–10); preclinical-only compounds cap at 6.
30% — Adverse-event profile. Severity and frequency of reported side effects, including GI events, cardiovascular signals, hypoglycemia, and long-term organ effects.
20% — Regulatory status. FDA approval, EMA approval, or status in active clinical trials. Compounds under safety warnings are penalized.
10% — Community-reported outcomes. Reddit, forum, and published case-report signal beyond formal trials. Used as a late-stage tiebreaker, not a leading factor.

9–10Well-studied, FDA-approvedLarge-trial evidence, established long-term safety. Examples: semaglutide, tesamorelin at approved doses.

7–8Mostly safe, some caveatsPhase 2/3 evidence or long community track record with known manageable side effects. Routine monitoring recommended.

5–6Mixed dataLimited clinical trials, mostly community/preclinical data. Real but uncertain risk profile.

3–4Caution advisedKnown side-effect patterns, thin safety data, or compounds under active regulatory scrutiny.

1–2Significant risk signalsDocumented serious adverse events (cardiovascular, hepatotoxicity, contamination) or withdrawn regulatory status.
