§ A · Identity
Primary sequence— sequence not captured —
MW · CLASS · Two-component blend — recombinant follistatin (FST-315 or FST-344, vendor-dependent) plus B-vitamin complex (composition varies)CATEGORY · Blend, GH-stack

Tier 4. Vendor-marketed blend combining a follistatin protein component with B-vitamin complex; presented commercially as a body-composition adjunct. Neither the specific follistatin source nor the B-vitamin formulation is consistently disclosed across sellers; the blend has no published clinical trial.

§ B · Mechanism of action

Pharmacological rationale combines myostatin/activin sequestration via follistatin (see follistatin component pages) with general metabolic-cofactor support via B vitamins. The B-vitamin component does not have specific peptide-class pharmacology; it is a nutritional adjunct.

§ C · Human clinical evidence

None for the blend. Follistatin component evidence is preclinical (or AAV-gene-therapy clinical for the FST-344 isoform). B-vitamin complex efficacy as a body-composition aid is not supported by separate peptide-research literature.

§ F · Safety signal

No combined safety database. The injectable B-vitamin component has known adverse events on its own (anaphylactoid reactions to thiamine, niacin flushing) that compound the unknown follistatin-injection risk.

§ H · Regulatory status

Regulatory status

FDA status:
Not FDA-approved
§ I · Notable gaps and controversies

The blend exists primarily as a marketing construct rather than a pharmacological design. Vendors do not consistently disclose the follistatin isoform or the B-vitamin formulation; product-to-product comparability is not assured.
