Frequently Asked Questions

What is GDF-8?
In this product, GDF-8 is a synthetic 23-amino-acid peptide (sequence WRQNTRYSRIEAIKIQILSKLRL-NH2) corresponding to a region of the myostatin (GDF-8) prodomain. It has the molecular formula C130H222N42O32 and a molecular weight of approximately 2885.5 g/mol. It is a defined peptide fragment, not the full myostatin protein. Pure Health Peptides supplies it as a lyophilized powder strictly for in vitro laboratory research.
Is this the myostatin protein?
No. Full myostatin (GDF-8) is a large protein produced as a 375-amino-acid precursor. This product is a short 23-residue synthetic peptide corresponding to residues 21-43 of the myostatin prodomain (the rodent sequence, which differs from the human sequence at two positions). It is supplied as a defined peptide fragment characterized by its sequence.
What is GDF-8 studied for in research?
In controlled laboratory settings, this peptide is studied as a myostatin-derived fragment. Research literature reports that peptides corresponding to this prodomain region are examined as inhibitors of myostatin signaling in cell-based study models. These are research findings; all applications are non-clinical.
What are GDF-8's chemical specifications, and what size does it come in?
This GDF-8 peptide has the molecular formula C130H222N42O32 and a molecular weight of approximately 2885.5 g/mol (refer to the lot-specific Certificate of Analysis for the exact value). It is supplied as a lyophilized powder in 1 mg and 2 mg sizes at greater than or equal to 98% purity (HPLC). Store in a cool, dry place away from light and moisture, and consult the Safety Data Sheet before handling.
Where can I buy GDF-8, and is it third-party tested?
This GDF-8 peptide is available from Pure Health Peptides as research-grade material in 1 mg and 2 mg sizes at greater than or equal to 98% HPLC-verified purity. Every production lot is third-party tested in the US, with a lot-specific Certificate of Analysis available for verification.
Is GDF-8 intended for human or clinical use?
No. GDF-8 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.
