Muscle Building & Performance
Myostatin inhibition, growth factor and hypertrophy-oriented peptides used in muscle research models. 9 profiles
ACE-031
Soluble ActRIIB-Fc decoy receptor for myostatin studied as a muscle-mass candidate; a protein biologic, not a peptide, with a discontinued clinical program.
Read profile →02Follistatin 344
Natural glycoprotein isoform (344 amino acids) that neutralizes myostatin; research interest centers on gene-therapy delivery to increase muscle mass.
Read profile →03GDF-8 (Myostatin)
Myostatin (GDF-8), a TGF-beta-family protein that limits skeletal muscle growth; a research target for muscle-loss conditions.
Read profile →04IGF-1 LR3
Engineered 83-amino-acid analog of insulin-like growth factor 1 with reduced binding-protein affinity, used in growth research.
Read profile →05IGF-DES (1-3)
Naturally occurring truncated IGF-1 variant lacking the first three amino acids; high receptor potency with a very short half-life.
Read profile →06Muscle Fiber Type Conversion Analogs
Catalog heading about shifting muscle fiber types; no defined peptide product with published evidence under this name.
Read profile →07Myostatin Inhibitor Fragments (Expanded)
Catalog category for short peptides claimed to block myostatin; myostatin biology is real, but these fragment products are not characterized.
Read profile →08PEG-MGF (PEGylated Mechano Growth Factor)
The PEGylated form of mechano growth factor, an IGF-1 splice variant studied for satellite-cell activation and muscle repair in animal models.
Read profile →09YK-11
A synthetic steroidal research compound grouped with SARMs in vendor catalogs; not a peptide, with very limited peer-reviewed data.
