How it works
Thought to reproduce hGH's fat-mobilizing (lipolytic) activity without stimulating IGF-1 or growth/blood-sugar effects; mechanism not well defined.
Known / used for
Fat loss / body composition; some recovery and sleep claims.
Positives
Reported (mostly preclinical/anecdotal) lipolysis while avoiding hGH-type side effects.
Negatives & risks
No clinical trials on the unmodified fragment; human claims unproven; mechanism unclear; gray-market purity concerns.
What people like most (reported community sentiment - not endorsement)
Perceived fat loss without HGH's systemic effects; anecdotal better sleep/recovery.
