You've brought the peptide back to life

The oil and gas seeps and hydrate communities host chemoautotrophic symbionts that are unique biogenic communities with a high diversity of organisms, including bacteria consortia that support numerous, as yet unknown, biogeochemical processes

These include intrinsic primary afferent neurons (IPANs) that sense luminal contents, interneurons responsible for information processing, motor neurons that regulate smooth muscle contraction and glandular secretion, as well as enteric glial cells that support and modulate neural function

Proper handlinggently rolling, not shaking, the vialis also crucial to preserve the delicate peptide chains
