What is Follistatin-344?

Follistatin is a glycoprotein that binds and blocks activin and myostatin. FST-344 is the full precursor form, which is processed into FST-315.

It’s a key tool in myostatin research.

What studies report about Follistatin-344

Lee and McPherron reported in PNAS (2001) that follistatin overexpression in mice produced large increases in muscle mass.

Gene therapy studies with FST-344 followed in primates.

The full list of Follistatin-344 papers is on PubMed, and most abstracts are free to read.

Follistatin-344 mechanism of action

Follistatin binds activin and myostatin tightly and stops them reaching their receptors. With myostatin blocked, muscle cells grow larger.

FST-344 is the longer form that gets processed into the circulating FST-315, which has a lower affinity for cell surfaces.

Follistatin-344 1mg specifications

• Compound: Follistatin-344
• Other names: FST-344
• Amount: 1mg
• Form: lyophilized (freeze-dried) powder
• Made: synthesized and lyophilized in the USA
• SKU: Follistatin-344-1mg

How to mix Follistatin-344 1mg

With 1mg in the vial, common water volumes work out like this:

• 1mL of water: 1mg per mL
• 2mL of water: 0.5mg per mL

Use sterile bacteriostatic water and add it slowly, aiming at the glass instead of the powder. A gentle swirl is all it needs.

Dry vials last longest frozen at -20°C. Reconstituted solution goes in the fridge and is best used within four weeks or so.

Planning a study with Follistatin-344 1mg

Count the total milligrams across every group and time point, and round up. Running out halfway and switching lots adds a variable you didn’t plan for.

Follistatin-344 vs related compounds

In short, Follistatin-344 binds myostatin and activin directly. Here’s how its neighbors differ:

• IGF-1 LR3 is an 83-amino-acid IGF-1 analog that avoids binding proteins and lasts for hours
• MGF is the E-domain peptide from the muscle-specific IGF-1 splice variant
• PEG-MGF is MGF with a PEG chain added so it lasts much longer
• ACE-031 is a decoy activin receptor that soaks up myostatin

Muscle research uses two routes: the IGF-1 side (IGF-1 LR3 and the MGF peptides) and the myostatin side (ACE-031 and follistatin). All of them are on our muscle peptides page.

Often ordered with Follistatin-344 1mg

• IGF-1 LR3 1mg (Receptor Grade), an IGF-1 analog
• MGF 5mg (Mechano Growth Factor), an IGF-1 splice variant peptide
• PEG-MGF 5mg, a pegylated MGF
• ACE-031 1mg, a soluble activin receptor fusion protein

The full range is on the research peptides page. For this research area, go to muscle peptides.

Follistatin-344 1mg from a store that sells peptides only

Our catalog is narrow on purpose: research peptides, blends and cosmetic peptide powders. That keeps stock moving, so the vial you order isn’t one that has been sitting on a shelf for a year.

Support is by email, through the contact page. It covers order questions, lot numbers and requests for documents.

Delivery for Follistatin-344 1mg orders
