Colostrum for peptide users — the growth factor connection

Bovine colostrum — the first milk produced after birth — has emerged as one of the most interesting supplements for peptide users. Rich in immunoglobulins, lactoferrin, and critically, growth factors including IGF-1 and TGF-β, colostrum provides a natural complement to growth hormone peptide protocols.

The Growth Factor Connection

Colostrum contains several growth factors that are directly relevant to peptide users:

IGF-1 (Insulin-like Growth Factor 1): The primary downstream mediator of growth hormone effects. When your GH peptides increase GH production, the liver responds by producing more IGF-1. Colostrum provides additional IGF-1 support.

TGF-β (Transforming Growth Factor Beta): Supports tissue repair and immune regulation. Particularly relevant for BPC-157 and TB-500 users focused on recovery.

Gut Health Benefits

For GLP-1 users, colostrum's gut-protective properties are especially valuable. The immunoglobulins in colostrum support gut lining integrity, which can be compromised by months of altered gastric motility on GLP-1 medications.
