Key Findings
- Cortagen and similar peptides produced effects that were specific to the type of rat tissue they were applied to.
- These tissue‑specific actions were observed across rats of various ages.
- No universal or systemic effect was seen; each peptide acted mainly on its native organ culture.
Practical Outcomes
- At this stage there’s no actionable dosing or protocol for humans. The study suggests that Cortagen may have organ‑specific activity, but without in‑vivo or clinical data, biohackers should treat these findings as preliminary and await further research before incorporating it into longevity or performance regimens.
Summary
The researchers tested Cortagen and several other brain‑, liver‑, and thymus‑derived peptides on rat tissue slices in a dish. They found that each peptide tended to affect only the type of tissue it came from, showing tissue‑specific actions, but the work was purely in vitro and done on rats of different ages.
Abstract
There was studied the effect of polypeptide preparations isolated from the cerebral cortex (Cortexin), epiphysis (Epithalamin), liver (Hepalin), thymus (Thymalin) and small synthetic peptides--Cortagen, Epitalon, Livagen, Vilon on the development of explants from the cerebral cortex, brain subcortical structures, liver and thymus of rats of various age. With respect to the applied concentrations of the investigated peptides, they exerted tissue-specific effects in the organ-typical culture of animal tissues.
