GDF-8 in brief
GDF-8 comes in one strength, 1mg x 10 vials, at $109.07 for the box of ten ($10.91 a vial, $10.907 per mg).
Nothing is held on the shelf: this is a special-order line, brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
What GDF-8 is
GDF-8, growth differentiation factor 8 or myostatin, is a member of the TGF-beta family supplied as the recombinant mature protein: a disulfide-linked dimer of two 109-residue chains, each with the cystine-knot fold characteristic of the family. It is a protein, expressed and refolded, not a synthetic peptide.
Its certificate reports purity and identity by the methods it names (size exclusion and SDS-PAGE for purity), endotoxin and the net content, and the desk answers for an activity figure on a particular batch. Keep frozen and avoid freeze-thaw cycles.
GDF-8 beside Follistatin and ACE-031
Its neighbours: Follistatin at $18.387 per mg at 1mg (FN1, in 50-box lots), N-glycosylated, so its mass is no single number, where GDF-8 comes to about 25 kDa; ACE-031 at $1.980 per mg at 1mg (AE1, in 50-box lots), about four times GDF-8’s size.

Buy GDF-8 in bulk
GDF-8 is sold in bulk by the sealed box of ten vials, and every account starts at list price. Two discounts can lower it, the size of one order (from $5,000 of goods) or the account’s tier (from lifetime paid spend), and the better one applies, never both. Priced below on F81, 1mg x 10 vials.

Specification
The limits this compound is supplied to. Its purity limit is stated on each batch certificate rather than here, and the desk gives it for a batch before you order.
| Purity | On the batch certificate, with the method named there: size exclusion and SDS-PAGE for protein and glycoprotein lines, not an RP-HPLC area percentage |
|---|---|
| Identity | Against the reference standard by the method the batch certificate names |
| Endotoxin | Reported on the batch certificate |
| Net content | Label claim ± 5 % |
| Closure | 2 mL glass vial, bromobutyl stopper, aluminium flip-off seal |
| Storage | −20 °C, dark and dry; brief ambient transit tolerated |
| Shelf life | 24 months from manufacture; retest date on the batch record |

Questions about GDF-8
Is myostatin, or growth differentiation factor 8, the same as GDF-8?
Yes. Myostatin, growth differentiation factor 8 and GDF-8 are names for the same thing. Myostatin is the protein’s common name and GDF-8 short for growth differentiation factor 8, its name within the TGF-beta family; this line is the recombinant mature protein, a disulfide-linked dimer of two 109-residue chains. The certificate and the vial label carry GDF-8, which is the name the batch is released under.
Which other proteins on this list are made of two chains?
Three: ACE-031, insulin and HCG, and HMG is a mixture of two more. ACE-031 is, like GDF-8, a homodimer whose two identical halves are linked by disulfides, but each of its halves carries an IgG1 Fc, so the pair reaches about 100 kDa against GDF-8’s 25 or so from two 109-residue chains. Insulin is two chains, of 21 and 30 residues, joined by two disulfides. HCG pairs an alpha with a beta subunit with no covalent bond between them, and HMG mixes two such hormones, FSH and LH.
How much does GDF-8 cost?
It is sold only by special order, 50 boxes per strength, at $109.07 a sealed box of 10 vials, which works out at $10.907 per mg. The smallest order is 50 boxes of F81, $5,453.50 of goods, with freight included to a US address. The price per vial is in this page’s price table.
What does GDF-8 cost per mg?
It is offered in one size, F81 at 1mg x 10 vials, which works out at $10.907 per mg at $109.07 a sealed box of 10 vials, sold by special order with a 50-box minimum. Freight included to US addresses from $1,000 of goods.
Can I buy a single vial of GDF-8?
No, and not a single box either. GDF-8 is a special-order line, brought in on a 50-box minimum rather than held in stock, so the smallest order is 50 sealed boxes of one strength: for F81, 1mg x 10 vials, that is 50 boxes at $109.07, $5,453.50 of goods. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.
Is GDF-8 in stock today?
No. F81 is special order: brought in on a 50-box minimum rather than held in stock; ask the desk for the date before ordering.
How is GDF-8 stored?
At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.
What is in a box of GDF-8?
Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. GDF-8 is supplied as a powder in a sealed glass vial and in no other presentation. Boxes are not split.
Is a certificate of analysis (COA) provided for GDF-8?
Yes. For GDF-8 the batch certificate reports its purity and identity by the methods it names (size exclusion and SDS-PAGE for purity), endotoxin and its net content. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.
Is this for human use?
No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
