Company Overview

Molecular Edge positions itself at the intersection of growth hormone secretagogue research, anti-aging biology, and specialty peptide compound supply. The medgepeptides.com domain reflects a specific domain expertise commitment, and the catalog delivers on this through GHRH/GHRP combinations available as standalone compounds and as a triple-peptide research blend — a format researchers studying additive or synergistic GH secretion biology find useful for reduced procurement complexity.

The 26-listing catalog is compact but intentionally curated: every product maps to a distinct research application, and the compound selection reflects current literature focus areas in GH axis biology, telomere/longevity research, antimicrobial peptide immunology, and metabolic-rate modulation.

Catalog & Products

Growth Hormone Secretagogue Research: The Triple Stack Advantage

The growth hormone-axis segment is the most developed section of the Molecular Edge catalog, with three distinct GH-secretagogue combinations available alongside individual compounds:

CJC1295 No-DAC + Ipamorelin + GHRP-2 Triple Blend (2mg + 2mg + 2mg per vial at $80): This combination represents the most complex GH secretagogue research formulation in the Molecular Edge catalog. The three components activate distinct but synergistic mechanisms:

CJC-1295 Without DAC (Modified GRF 1-29) stimulates the GHRH receptor to produce pulsatile GH release. Without the drug affinity complex modification, the peptide has a shorter half-life more closely matching physiological GHRH release kinetics, which some researchers prefer for studies examining pulsatile GH secretion patterns.

Ipamorelin is a selective ghrelin receptor agonist and the most selective GHRP-class peptide, producing GH release with minimal cortisol or prolactin elevation. Its selectivity makes it the preferred GHRP for researchers who need to isolate GH secretagogue effects without contamination from stress-hormone cross-activation.

GHRP-2 (Growth Hormone-Releasing Peptide-2) is a synthetic hexapeptide that activates the GHS-R1a receptor through both ghrelin-dependent and potentially ghrelin-independent pathways. GHRP-2 is among the most potent GHRP-class compounds for GH release stimulation, and its combination with Ipamorelin enables comparative GHRP selectivity studies within the same experimental framework.

The triple combination at 2mg each (6mg total) provides researchers with the ability to examine additive GH secretion biology, where each secretagogue contributes independently and potentially synergistically through different receptor populations. At $80 for 6mg total ($13.33/mg blended), this is a cost-effective way to access triple-mechanism GH research without separately procurement-managing three compounds.

IPAMORELIN/CJC-1295 Blend (No DAC) at $80 is the standard dual-secretagogue combination for researchers studying GHRH/GHRP synergy without the GHRP-2 addition.

CJC-1295 No DAC (10mg) at $95 ($9.50/mg) provides larger-format access to the GHRH analog for researchers with higher-volume protocols.

Hexarelin (5mg at $95 = $19/mg): Hexarelin is a synthetic hexapeptide GHRP with some of the highest GH-releasing potency among GHRP-class compounds. Unlike Ipamorelin, Hexarelin produces more significant cortisol and prolactin responses at higher doses, making it useful for comparative GHRP side-effect profile research alongside more selective analogs.

LL-37: The Antimicrobial Peptide for Immunology Research

LL-37 (10mg at $95 = $9.50/mg) is one of the most scientifically significant catalog entries at Molecular Edge. LL-37 is the only processed form of the human CAMP gene product (Cathelicidin Antimicrobial Peptide) and the sole human cathelicidin. Its research applications span multiple fields:

Innate immune defense: LL-37 disrupts bacterial membrane integrity through amphipathic helix formation, with activity against gram-positive, gram-negative, and mycobacterial pathogens, as well as antifungal and antiviral properties.

Wound healing: LL-37 promotes re-epithelialization, keratinocyte migration, and angiogenesis in wound models — effects mediated through EGFR transactivation and P2X7 receptor signaling.

Anti-inflammatory modulation: At sub-antimicrobial concentrations, LL-37 can exert anti-inflammatory effects through TLR4 antagonism, reducing LPS-stimulated cytokine release. This dual antimicrobial/anti-inflammatory profile has generated research interest in sepsis biology and chronic wound models.

Anti-biofilm: LL-37 disrupts established biofilms at concentrations lower than those required for planktonic bacterial killing, making it a research tool for biofilm-related infection models.

At $9.50/mg for a 10mg vial, Molecular Edge offers one of the more accessible per-mg prices for this specialty compound — which often ranges from $10–$20/mg from other U.S. research vendors. This positions Molecular Edge as a relevant source for immunology and wound biology researchers.

Anti-Aging & Bioregulator Research

Epithalon (50-Vial Pack at 30% Discount, ~$215) and EPITALON (Standard) are available in both bulk and standard formats. Epithalon (also spelled Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from the natural Epithalamin complex secreted by the pineal gland. Research into Epithalon has examined:

• •Telomere biology: Evidence from in vitro and animal models suggests Epithalon may activate telomerase, potentially extending telomere length in aging cell populations.
• •Melatonin regulation: Epithalon has been studied for its ability to normalize melatonin secretion in aging animals.
• •Antioxidant defense: Research in older rodent models has demonstrated upregulation of superoxide dismutase and other antioxidant enzymes following Epithalon treatment.

The 50-vial bulk pack at approximately $4.30/mg (estimated from the $215 package at 30% off standard pricing) represents a substantial discount for researchers running longitudinal anti-aging study designs requiring extended compound availability.

GHK-Cu in Multiple Formats:

• •GHK-Cu 500mg bulk (5 × 100mg packs) at $170 = $0.34/mg — an exceptionally low per-mg price for this copper tripeptide
• •GHK-Cu/BPC-157/TB-500 triple healing combination
• •The $0.34/mg bulk price is among the lowest verified GHK-Cu pricing from any U.S. domestic source, making Molecular Edge a strong candidate for cosmetic-science researchers with high-volume GHK-Cu protocols

Frontier Metabolic & Exercise-Physiology Research

SLU-PP-332 (250mcg × 60 Tablets at $110) and in an alternate presentation format at $225: SLU-PP-332 is a first-in-class ERRα/β/γ (estrogen-related receptor) agonist studied as an exercise mimetic. It activates transcriptional programs associated with endurance training — particularly PGC-1α coactivation, mitochondrial biogenesis, and oxidative phosphorylation upregulation — without physical activity. Animal research has shown exercise-like benefits in metabolic, cardiac, and muscle physiology contexts. For researchers studying the transcriptional mechanisms of exercise adaptation, SLU-PP-332 provides a pharmacological tool to isolate receptor-mediated effects.

Tesofensine ($250, with alternate pricing): A triple monoamine reuptake inhibitor (serotonin, norepinephrine, dopamine) originally studied in neurodegeneration pharmacology. Metabolic research repurposed Tesofensine based on its strong appetite-suppressing and weight-reducing properties in Phase 2 obesity clinical trials — showing effects approximately 2-3 times larger than single-mechanism monoamine inhibitors. Research into the combined contribution of each neurotransmitter pathway to appetite regulation makes Tesofensine a useful pharmacological probe.

MOTS-c ($110 = $11/mg for 10mg): A mitochondria-derived peptide with established research roles in AMPK-mediated glucose homeostasis, fatty acid oxidation, and metabolic rate regulation during caloric restriction. MOTS-c research has expanded into exercise biology and age-related metabolic dysfunction prevention.

5-Amino-1MQ ($255): NNMT inhibitor for NAD+ metabolism and adipocyte biology research.

Semax (30mg vial at $75 = $2.50/mg): This pricing makes Molecular Edge one of the more accessible sources for Semax, a synthetic ACTH analog studied in BDNF upregulation, neuroprotection, and cognitive enhancement research paradigms. At $2.50/mg, this is competitive.

Tesamorelin ($110 = $11/mg for 10mg): 44-amino acid GHRH analog studied in visceral adiposity reduction and body composition research.

Thymosin Alpha-1 ($130 = $13/mg for 10mg): Synthetic thymic peptide studied in immune modulation, T-cell maturation support, and antiviral defense research.

Multi-Compound Healing Formulations

KLOW Blend (80mg = BPC-157/TB-500/KPV/GHK-Cu at $375 = $4.69/mg): The multi-compound healing blend provides BPC-157, TB-500, KPV, and GHK-Cu in a single preparation.

BPC-157 (standalone at $200 = $20/mg for 10mg): Individual BPC-157 for researchers who prefer single-compound isolation.

NAD+ Biofermented (1000mg at $300 = $0.30/mg): The biofermented format distinguishes this NAD+ listing from standard synthetic NAD+. Some researchers prefer biofermented presentations based on hypotheses about structural authenticity, though both formats provide the NAD+ cofactor for cellular energy metabolism and sirtuin activation research.

R-30 ($275): A specialty catalog entry that rounds out the compound selection for researchers studying less-common peptide pharmacology.

Pricing Analysis

The GHK-Cu bulk price ($0.34/mg) and Semax price ($2.50/mg) stand out as particularly competitive anchor points. LL-37 at $9.50/mg is accessible for a specialty immunological peptide.

Quality & Testing Standards

Molecular Edge follows the third-party analytical testing standard for documented U.S. research compound suppliers: HPLC purity characterization and mass spectrometry identity confirmation per batch, with COA documentation available. The complex synthesis requirements for compounds like LL-37 (37 amino acids, amphipathic structure) and the triple GH blend (three independently synthesized peptides) make per-batch COA verification particularly important.

Researchers should confirm COA documentation covers purity (HPLC area%) and identity (LC-MS molecular weight) for each compound in combination formulations — verifying that all three GH-stack components meet identity specifications, not just the blend overall.

Shipping & Customer Service

Molecular Edge ships domestically within the United States with standard and expedited shipping options. Processing times follow the standard 1–3 business day window. Lyophilized peptide compounds ship with appropriate cold-chain handling for short-transit stability, with standard recommendations for refrigerated storage upon receipt.

The catalog's complexity (specialty compounds, multiple blend formats, bulk presentations) means that customer service needs to be capable of handling compound-specific questions. The research-oriented customer base expects accurate technical responses to questions about reconstitution protocols, storage conditions, and compound-specific research parameters.
