Fat loss peptides range from FDA-approved GLP-1 receptor agonists — some of the most extensively studied weight-loss medications ever developed — to experimental metabolic compounds with only animal-model data. This list is organized by strength of evidence, not hype. Every entry is derived from the research we've indexed; no compound is positioned as universally "best."

Recovery peptides are among the most researched in the biohacking community, but nearly all current evidence comes from animal models. The compounds below appear most frequently in preclinical tissue-repair research and community experience reports. No peptide on this list has completed a human clinical trial confirming recovery benefits; claims are based on mechanism and animal data.

Peptides with proposed sleep-modulating properties act through several different mechanisms — direct delta-wave induction, circadian rhythm regulation via melatonin, and anxiolytic effects that indirectly improve sleep onset. The catalog of well-evidenced sleep peptides is small; most evidence comes from animal studies or small, non-peer-reviewed clinical trials. As we expand the catalog, this list will grow.

Longevity peptides is a category where enthusiasm far outpaces evidence. Every compound below has been studied in the context of aging biology — telomere dynamics, mitochondrial function, immunosenescence, or tissue maintenance — but none has demonstrated life-extension in humans. We present them ranked by breadth and quality of current evidence, not by promise.

The cognitive peptide space is dominated by two Russian-developed neuropeptides — Semax and Selank — whose evidence base is largely limited to small, non-peer-reviewed clinical studies conducted in Russia and Eastern Europe. Western literature consists primarily of animal data. We are indexing this category honestly: currently, the catalog has two peptides with documented cognitive-relevant mechanisms and some human-use data.

Connective tissue repair peptides are among the most sought-after compounds in both clinical rehabilitation research and the broader recovery-focused community. None of the compounds below are approved for this use, and human clinical trial evidence is largely absent. All rankings reflect preclinical evidence quality and mechanistic plausibility, not proven clinical outcomes.
