Frequently Asked Questions

What is Follistatin-344?
Follistatin-344 is a chemically synthesized fragment derived from the follistatin-344 protein isoform, prepared by solid-phase peptide synthesis (SPPS) and supplied as a lyophilized research-grade reference material. Pure Health Peptides supplies it strictly for in vitro laboratory research.
Why is Follistatin-344 characterized by its COA rather than a single fixed molecular formula?
Because it is supplied as a synthetic fragment derived from the follistatin-344 isoform rather than the full-length glycoprotein, its exact chemical characterization - including sequence, molecular weight, and analytical purity - is reported per lot on the Certificate of Analysis rather than as one fixed listing formula.
What is Follistatin-344 studied for in research?
In controlled laboratory settings, Follistatin-344 is studied as a follistatin-derived fragment. Research literature reports that follistatin binds and neutralizes TGF-beta-family ligands, including myostatin (GDF-8) and activin, in study models. These are research findings; all applications are non-clinical.
How does Follistatin-344 differ from Follistatin-315?
Follistatin-344 and Follistatin-315 are alternatively spliced isoforms of the follistatin protein; FS-344 is the longer precursor form and FS-315 is a shorter processed isoform. They are supplied as separate, individually characterized research fragments; refer to each lot-specific Certificate of Analysis for exact identity.
What size does Follistatin-344 come in, and is it third-party tested?
Follistatin-344 is supplied as a lyophilized research material in a 1 mg vial. Every production lot is third-party tested in the US, with a lot-specific Certificate of Analysis available for verification. Store in a cool, dry place away from light and moisture.
Is Follistatin-344 intended for human or clinical use?
No. Follistatin-344 is for research use only and is not intended for human or veterinary use. It has not been evaluated by the FDA and is not a drug, food, cosmetic, or dietary supplement. It is supplied only to qualified research professionals for in vitro laboratory research, and KYC verification is required prior to fulfillment. Any use outside of controlled in vitro research is strictly prohibited.
