Compound Database

Peptide and GLP-1 compound database with citation-backed pharmacokinetic data.

The Halflife compound database indexes 45 peptides, GLP-1 receptor agonists, and related bioactive compounds. Each compound entry links to a dedicated page containing structured half-life values, mechanism summaries, and source citations from published biomedical literature. FDA prescribing labels are used as the primary source for approved compounds. Research compounds are labeled where human pharmacokinetic data is absent.

All compound data is citation-backed. Sources include FDA prescribing labels, PubMed-indexed studies, and published pharmacokinetic trials. No unverified or anecdotal data is included in the database. Each compound page contains its own reference set.

Database Structure & Methodology

How compound data is structured and sourced.

Individual Compound Pages

Each of the 45 compounds has a dedicated page containing structured pharmacokinetic data, mechanism summary, route of administration, and evidence level classification. This index page functions as a navigational layer — full scientific detail lives on individual compound pages.

Citation-Backed References

Each compound page contains its own reference set. FDA-approved compounds cite FDA prescribing labels (NDA numbers provided). Research compounds cite PubMed-indexed studies, published pharmacokinetic trials, or patent literature where formal human data is absent.

Evidence Classification

Compounds are classified into three evidence tiers: FDA Approved (human PK from prescribing labels), Clinical Data (published human PK studies), and Preclinical / Estimate (animal data or community estimates where human PK is absent).
