More recently, LA has been linked to inhibition of myosin light chain kinase, which likely reduces tension on actin filaments, thereby facilitating tight junction closure
Circadian and Neuroendocrine Effects Epithalon influences pineal gland function and circadian rhythm regulation
It is also one of the three actives in the Peptual transdermal patch he endorses, alongside BPC-157 and NAD+: BPC-157: ~2000 mcg NAD+: ~250 mg GHK-Cu: ~10 mg The patch combines tissue repair (BPC-157), cellular energy (NAD+), and collagen synthesis (GHK-Cu) in a sustained-release format (source)
The proposed mechanism is restoration of normal melatonin production in individuals with age-related decline
