FLGR242 vs igf-1 lr3
updated
FLGR242 (tier F) vs igf-1 lr3 (tier F): what each is, why each got its grade, half-life and source counts side by side.
FLGR242 · tier F
FLGR242 is a seller name for a claimed follistatin-albumin construct. The seller now publishes partial specifications, but the complete construct and independent characterization remain unresolved.
tier rationale
F-tier follows from the unresolved complete identity and empty administration record. More detailed seller copy does not substitute for independent characterization.
igf-1 lr3 · tier F
a free-circulating IGF-1 analog used by bodybuilders chasing muscle growth. sustained IGF-1 elevation carries one of the clearer cancer-risk signals in the literature.
tier rationale
F-tier because the risk profile is qualitatively different from the D-tier compounds. D-tier is 'this doesn't really work' or 'this is obsoleted by a cleaner alternative.' F-tier is 'the mechanism itself carries a specific, well-documented, serious risk that the use case doesn't justify.' IGF-1 LR3 is engineered specifically to bypass the regulatory system that evolution put in place to keep IGF-1 signaling controlled, and IGF-1 elevation is one of the best-characterized cancer risk factors in clinical epidemiology. The muscle-growth benefit is real; so is the risk. The tier reflects the judgment that the calculation doesn't work out.
