Description
EU Peptide Sciences supplies Follistatin 315 to research groups working on myostatin and activin binding assays and related model systems.
Follistatin is described in the literature as an activin-binding glycoprotein that antagonises members of the TGF-beta superfamily. FST-315 is the circulating isoform; FST-344 carries the additional C-terminal extension.

Compound profile: Follistatin 315
Follistatin 315 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 315 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.
Follistatin 315 research applications
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 the peptide 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.
Work on muscle-cell hypertrophy models typically measures a defined endpoint rather than an outcome, which is why the material is dosed into the system at a fixed concentration and compared against a vehicle control.
TGF-beta superfamily signalling is examined with assays that report a single variable, so this compound is introduced under tightly held conditions and the readout is compared with an untreated arm.

Storage and handling
Follistatin is a glycoprotein, and glycosylation affects behaviour. Confirm expression system and glycosylation status when comparing sources.
Keep the sealed vial in a freezer at -20 °C, protected from light. Lyophilised material is stable for extended periods under those conditions.
After reconstitution, refrigerate at 2–8 °C, use a bacteriostatic diluent where repeated withdrawal is planned, and avoid repeated freeze-thaw cycles. The full routine is set out in the peptide storage guide.
Stock-concentration arithmetic for a 1mg vial of this material: 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.
Choosing between Follistatin 315 and alternatives
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 315 is catalogued under myostatin inhibitor peptide for sale. Researchers working in the same area also look at peg mgf and follistatin 344. The whole peptide sciences range is listed under peptide sciences peptides and research peptides for sale.
Analytical verification
Independent testing sits between production and release. Identity, purity and mass are verified analytically, and the matching certificate of analysis is issued for the batch you are sent.
Labelling records compound, quantity and batch so that a result can always be traced to the material that produced it. Request a certificate at support@eupeptidesciences.com, and see how to read a peptide certificate of analysis for what to check on it.
Follistatin 315: common 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 315 for human use?
No. Follistatin 315 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.
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.
Where can I buy follistatin 315?
