FLGR242 vs follistatin 344
updated
FLGR242 (tier F) vs follistatin 344 (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.
follistatin 344 · tier F
myostatin biology is real. retail injectable follistatin-344 has zero human performance trials and major product-quality concerns.
tier rationale
F-tier because the compound carries multiple overlapping concerns: mechanistic (off-target TGF-β family binding with proliferation implications), clinical (zero human trials, no established safety profile), and market-quality (significant likelihood of product misrepresentation due to synthesis difficulty). Any one of these might keep a compound at D-tier. All three together, plus the absence of a proportionate documented benefit in humans, push it to F. The tier communicates that retail injectable FS-344 does not meet a defensible evidence, safety, or product-quality threshold.
