Follistatin 344: composition and identity
Follistatin 344 is an activin-binding glycoprotein that antagonises members of the TGF-beta superfamily.
It also appears in the literature as FST-344, FST-315.
FST-315 is the circulating isoform; FST-344 carries the additional C-terminal extension. It is supplied as a lyophilised vial, which keeps it stable in transit and simple to log into inventory.
Follistatin 344 is part of the EU Peptide Sciences and peptide science range, which lists 187 research compounds across 18 categories, each released against third-party analysis. Compare peptide sciences peptides, peptide sciences lab testing, and the peptide sciences website notes before you order.

Published work involving Follistatin 344
Follistatin binds and neutralises activin and myostatin, members of the TGF-beta superfamily that restrain muscle growth. FST-315 is the shorter circulating isoform and FST-344 is the longer form with an acidic C-terminal tail that reduces cell-surface binding.
Published work on Follistatin 344 sits in the research literature, always in vitro or in animal models. The main areas are:
- Myostatin and activin binding assays
- Muscle-cell hypertrophy models
- TGF-beta superfamily signalling
- Follicle-stimulating hormone regulation
- Isoform comparison between FST-315 and FST-344
- Tissue-distribution research
Myotube cultures and rodent models of muscle mass, with SMAD2/3 phosphorylation as a direct readout of activin and myostatin blockade.
Where muscle-cell hypertrophy models is the endpoint, Follistatin 344 is applied to a model system that has already been characterised, so that the sequence is the only variable under test.
Work on TGF-beta superfamily signalling typically measures a defined endpoint rather than an outcome, which is why Follistatin 344 is dosed into the system at a fixed concentration and compared against a vehicle control.

Buy Follistatin 344 1mg is listed for laboratory research only, and orders are accepted on that basis.
Storage, stability and preparation
Follistatin is a glycoprotein, and glycosylation affects behaviour. Confirm expression system and glycosylation status when comparing sources.
Frozen storage at -20 °C keeps the lyophilised powder stable. Allow the vial to reach room temperature before opening to prevent condensation.
Reconstituted solution belongs in the refrigerator and should be used within the window your protocol specifies. The full routine is set out in the peptide storage guide.
Stock-concentration arithmetic for a 1mg vial of Follistatin 344: dissolved in 1 mL of diluent it gives 1 mg/mL, in 2 mL it gives 0.5 mg/mL, and in 5 mL it gives 0.2 mg/mL. Fixing the diluent volume before the vial is opened means every experiment in a study starts from the same stock.
A first order for Buy Follistatin 344 1mg must meet the $100 minimum, which applies to the whole basket.
Follistatin 344 and related compounds
It works by binding the ligand, whereas most other muscle-signalling compounds here such as molecular weight of igf-1 act through a receptor.
Follistatin 344 is catalogued under myostatin inhibitor peptide for sale. Researchers working in the same area also look at follistatin 315 and peg mgf. The whole peptide sciences range is listed under peptide sciences peptides and research peptides for sale.
Cryptocurrency payment takes 5% off an order that includes Buy Follistatin 344 1mg, as it does for the rest of the range.
Purity, testing and batch records

Frequently asked questions
What is the difference between FST-315 and FST-344?
FST-315 is the shorter isoform and stays in circulation. FST-344 carries an extra tail that lets it bind cell surfaces, so it acts more locally.
Why is follistatin linked to myostatin?
It binds myostatin directly and stops it activating its receptor, which is why it is used to study muscle-growth inhibition.
Is Follistatin 344 for human use?
No. Follistatin 344 is supplied strictly as a research chemical for laboratory work. It is not a medicine, not a supplement and must not be administered to humans or animals.
How do I pay for Follistatin 344?
Payment is handled manually. After you place the order, our team emails payment instructions to the address on the order. Cryptocurrency payments receive a 5% discount, and the order ships once payment is confirmed. If the instructions have not arrived, write to support@eupeptidesciences.com.
Can I see a certificate of analysis for Follistatin 344?
Yes. Email support@eupeptidesciences.com with the compound or the batch reference on your label and the certificate covering that batch will be sent to you.
What is the minimum order and how long does delivery take?
The minimum order value is $100. Standard delivery takes 7–14 business days and express 3–7 business days, with rates shown at checkout. Orders of $250 or more ship express free, in discreet packaging with tracking.
Research use only. Sold as a research chemical for laboratory study. It is not a drug, food or cosmetic and carries no therapeutic indication.
