BPC-157 is among the most extensively cited healing peptides in current pre-clinical literature, with published rodent research spanning gastrointestinal mucosal integrity, tendon and ligament repair, neurological recovery, and anti-inflammatory cascade modulation. TB-500 research covers cardiac tissue repair, wound-healing acceleration, and musculoskeletal recovery biology.
The KLOW blend (BPC-157/TB-500/KPV combination) is listed in both single-vial and 10-vial formats, including the KLOW 80mg and the Klow Blend 80mg variants — providing flexibility for researchers running extended tissue repair protocol studies across multiple subjects.
BPC-157 is also available in capsule formulation (BPC Caps), extending format options for researchers exploring enteric peptide delivery in gastrointestinal and systemic inflammation models.
GLP-1 and Metabolic Research Compounds
The GLP-1 metabolic research segment at NG Peptide is notable for its depth beyond standard Semaglutide-only coverage. Tirzepatide (TRZ-2) is listed for GLP-1/GIP dual-agonist receptor biology research. Retatrutide (GLP-3 / AMP-3P) is available both individually and as part of the GLP3/CAGRI combination (Retatrutide 20mg/Cagrilintide 4mg), enabling researchers to study triple-receptor GLP-1/GIP/GCG pharmacology and combination metabolic signaling in pre-clinical models.
10-vial pack options for GLP-3 and Cagrilintide separately support extended metabolic research protocol supply needs.
Longevity and Bioregulator Compounds
The longevity and anti-aging research segment is a strength of the NG Peptide catalog. Epithalon (EPITALON) in single-vial and 50-vial discount bulk formats covers the telomere-associated tetrapeptide studied in cellular aging and longevity biology. GHK-Cu (Copper Peptide) is available individually, as a 10-vial pack, and in the GHK-Cu/KPV Blend for skin and tissue biology research.
Khavinson bioregulator coverage includes Cartalax (20mg), Testagen (20mg), and Prostamax (20mg) — tissue-specific short-chain peptides studied in gene regulatory activity and organ-specific cellular biology. MOTS-c (80mg), a mitochondrial peptide studied in cellular energy metabolism and insulin sensitivity, is also listed. NAD+ in 50mg single and 1,000mg bulk formats supports coenzyme biology research.
Cognitive and Neuromodulatory Peptides
Semax and Selank, the nootropic neuropeptides studied in BDNF/NGF signaling, neuroprotection, and anxiety-related CNS biology, are both listed — a catalog segment that not all domestic suppliers include. VIP (Vasoactive Intestinal Peptide) at 10mg supports autonomic and anti-inflammatory nervous system research. DSIP (Delta Sleep-Inducing Peptide), MOTS-c, SS-31, and additional compounds extend the specialty neuropeptide and mitochondrial biology research coverage.
Melanocortin Peptides
Melanotan-2 (MT-2 10mg) and PT-141 are listed at competitive price points, covering MC1R and MC4R receptor ligand research. PT-141 (Bremelanotide) is the active ingredient in Vyleesi, an FDA-approved compound for hypoactive sexual desire disorder.
Capsule and Specialty Formulations
Five capsule-format listings provide encapsulated delivery options: BPC Caps, KPV Capsules (500mcg/30 capsules), 5-Amino-MQ Capsules, SLU-PP-332 Capsules, and Tesofensine. These support researchers exploring oral or encapsulated compound delivery dynamics. The Super Blend multi-compound formulation and Lipo-C (B6/B12 lipotropic formula) round out the specialty formulation catalog.

Khavinson Bioregulator Peptides: A Unique Differentiator
One of NG Peptide's most distinctive features is its dedicated Khavinson peptide (bioregulator) section — a category that most US-facing suppliers ignore or carry only partially.
What are Khavinson peptides?
Khavinson peptides are short oligopeptides (2-4 amino acids) developed in St. Petersburg, Russia by Professor Vladimir Khavinson's research group at the St. Petersburg Institute of Bioregulation and Gerontology. They are proposed to work as epigenetic regulators, binding to promoter regions of specific genes and modulating expression patterns associated with tissue aging.
NG Peptide's Khavinson bioregulator lineup includes:
- •Testagen (LLW-V, 20mg): Testes-targeting tetrapeptide; testosterone production pathway research
- •Cartalax (20mg): Cartilage-targeting tetrapeptide; joint matrix repair research models
- •Prostamax (20mg): Prostate-targeting tetrapeptide; glandular health research
This bioregulator depth is rare among US-accessible suppliers and represents a significant value point for gerontology researchers specifically looking for these compounds.
