Growth factors and growth hormone-derived compounds

Built from index records dated 2026-10-09 Compiled by an automated pipeline, checked by The Peptide Observer editorial desk How this site works

Growth factors and growth hormone-derived compounds is a group of 6 entries in this index, of which this site describes 3 and holds 3 back pending review.

Only the described entries are counted anywhere on this page.

What this group is

This group holds 6 entries.

No entry in this group carries a receptor or a pathway in its records. The group is held together by the research subject its literature shares, not by a mechanism, and this site does not invent one for it.

The entries described here

IGF-1 LR3

12 records kept: 5 in rodents, 7 not stated. No public chemistry record was found under this name, so the entry describes a preparation, a protein or a mixture rather than one defined molecule.
IGF-1 DES

12 records kept: 7 in rodents, 5 not stated. No public chemistry record was found under this name, so the entry describes a preparation, a protein or a mixture rather than one defined molecule.
Mechano growth factor

12 records kept: 7 in rodents, 5 not stated. No public chemistry record was found under this name, so the entry describes a preparation, a protein or a mixture rather than one defined molecule.

Publication years of all 36 records kept for the described entries in this group. Oldest 1991, newest 2023. An old record is not a worse record, but a group whose marks all sit to the left has not been looked at recently.

What is held back

3 entries in this group are built and then held back, because publishing them without a qualified reviewer would risk being read as medical guidance. They are: Follistatin-344, ACE-031 and Somatropin. This page says nothing about what their records contain. Why entries are held back.

What is not known

Whether the members of this group have anything in common beyond what the counts above show. A shared receptor is a shared target, not a shared result.
What any of these entries does in a body. Nothing on this site has been read in full, and no record here has been appraised by anyone qualified to appraise it.
Anything at all about the held-back entries named above, beyond the fact that they exist and are being withheld.

Where this comes from

This page reprints no wording from the underlying index. These are the published records that index cites for the existence of this group, listed so the grouping can be checked rather than taken on trust.
