ResearchBPC-157
Also: Body Protection Compound-157, Bepecin
Muscle & RecoveryBPC-157 is a pentadecapeptide (15 amino acids) originally isolated from human gastric juice. It has been extensively studied for its cytoprotective and regenerative properties across multiple organ systems. Research shows significant tissue-healing effects in tendons, muscles, the GI tract, and the nervous system.
Cartalax
Also: Ala-Glu-Asp-Gly, AEDG Peptide (4-mer), Cartilage Bioregulator
Muscle & RecoveryCartalax is a tetrapeptide bioregulator specifically developed for joint health, cartilage repair, and connective tissue regeneration. Part of the Khavinson peptide family, it targets chondrocytes (cartilage cells) and connective tissue fibroblasts to restore gene expression and promote repair. Used in protocols for joint degradation, arthritis, and sports injury recovery.
Follistatin 344
Also: FST344, Follistatin-344
Muscle & RecoveryFollistatin 344 is a naturally occurring glycoprotein that acts as a powerful antagonist of myostatin (GDF-8) — the primary negative regulator of muscle growth. By blocking myostatin and activin signaling, Follistatin dramatically increases muscle fiber size and number. Its effects are among the most potent for muscle growth in preclinical models.
IGF-1 LR3
Also: Long R3 IGF-1, Insulin-like Growth Factor-1 Long Arg3
Muscle & RecoveryIGF-1 LR3 is a potent synthetic analog of insulin-like growth factor-1 engineered to have significantly reduced affinity for IGF-binding proteins, resulting in a half-life of approximately 20–30 hours compared to just minutes for native IGF-1. It acts directly on muscle, bone, and other tissues to promote growth and repair.
KLOW
Also: KLOW Protocol, KLOW Blend, KPV+BPC-157+TB-500+GHK-Cu
Muscle & RecoveryKLOW is a four-peptide research blend specifically engineered for comprehensive tissue repair and inflammation control. Each component targets a distinct but complementary biological pathway: GHK-Cu drives collagen gene expression and skin/tissue remodeling; KPV suppresses NF-κB-driven inflammation; BPC-157 promotes angiogenesis and gut/tendon healing; TB-500 enables cell migration and systemic repair. Together, they address recovery from multiple angles simultaneously.
PEG-MGF
Also: PEGylated Mechano Growth Factor, PEG-IGF-1Ec
Muscle & RecoveryPEG-MGF is the stable, long-acting form of Mechano Growth Factor — the local IGF-1 splice variant expressed in damaged or exercised muscle. While native MGF has a half-life of only minutes, PEGylation extends this to approximately 3–5 days, making it practical for research administration.
TB-500
Also: Thymosin Beta-4, Tβ4
Muscle & RecoveryTB-500 is commonly sold as the synthetic analog of Thymosin Beta-4 (Tβ4), but there is a critical distinction that is rarely explained clearly: 🔬 TB-500 FRAGMENT (7 amino acids — AA 17–23): The form most commonly sold as 'TB-500' is actually a synthetic 7-amino acid fragment derived from amino acids 17 through 23 of the full Thymosin Beta-4 molecule. This fragment contains the core actin-binding domain (LKKTETQ) responsible for local tissue repair and cell migration. It is highly targeted, fast-acting, and focused on rapid local healing at the site of injury. It does NOT replicate the full systemic effects of the complete 43-amino acid molecule. 🧬 THYMOSIN BETA-4 — Full Molecule (43 amino acids): The complete Thymosin Beta-4 (Tβ4) is a 43-amino acid polypeptide naturally produced in virtually every cell of the body. Unlike the fragment, the full molecule drives broad systemic healing — including stem cell activation, angiogenesis (new blood vessel formation), cardiac repair, neurological recovery, and immune modulation. It operates body-wide, not just at the injury site. ⚠️ These two forms are often marketed interchangeably, but they are NOT the same compound. Understanding which form you are working with matters for your research protocol.
Thymosin Beta-4 Full Fragment
Also: TB4 Full Fragment, Tβ4, Thymosin β4 (full length)
Muscle & RecoveryThymosin Beta-4 Full Fragment is the complete 43-amino acid form of TB-4, offering superior tissue repair, anti-inflammatory, and regenerative properties compared to the truncated TB-500 fragment.
