Explained

How much of the research is actually here?

Built from index records dated 2026-10-13 Compiled by an automated pipeline, checked by The Peptide Observer editorial desk How this site works

A small fraction of it: this site keeps at most twelve records per entry, and for some entries that is twelve out of tens of thousands.

The gap below is drawn to scale. If the kept portion is hard to see, that is the point of the picture.

What we actually know

Every entry here began with a literature search that returned some number of records. The index keeps up to twelve of them. Across the entries this site describes:

The widest gap among the entries described here. The literature search for Somatostatin returned 37,235 records; this site carries 12 of them. The accented sliver at the left-hand end is drawn to scale.

The eight entries whose searches returned the most records
Entry	Records the search returned	Records kept here	Share kept
Somatostatin	37,235	12	0.03 per cent
LL-37	2,666	12	0.45 per cent
GHRP-6	699	12	1.7 per cent
Thymosin beta 4	684	12	1.8 per cent
Delta sleep-inducing peptide	418	12	2.9 per cent
Gonadorelin	333	12	3.6 per cent
MOTS-c	272	12	4.4 per cent
Thymalin	243	12	4.9 per cent

Added up across every entry this site describes, the literature searches returned 44,232 records and this site carries 321 of them, which is 0.73 per cent of the total.

The widest gap among the entries described here is shown above. Several entries that are not described here at all have gaps far wider than that one.

What is not known

Which records were left out, and whether they point the same way as the ones kept. The kept records are the ones the search returned first, not the twelve most important ones.
Whether the kept records are representative of the field. Nobody has checked that, and no page on this site claims otherwise.
Whether a record that was kept has been superseded by a later one that was not.

How to read this

Treat a page here as an index card, not a summary of the literature.
Where the kept share is tiny, read the page as evidence that a subject exists and has been studied, and read nothing else into it.

Where this comes from

Retrieved and kept counts come from the record-gathering run recorded on each entry's evidence profile, with the date it was run.
