Growth Hormone Secretagogue
A stabilized GHRH analog that stimulates physiologic GH release and IGF-1 elevation, with well-documented effects on visceral adipose tissue. Used to investigate GH-axis physiology, visceral fat remodeling, HIV-associated lipodystrophy, and selective GH stimulation in metabolic and body-composition models. For research use only - not for human or veterinary use, diagnosis, or treatment.
Healing & Recovery
A combination of TB-500’s actin/angiogenesis signalling with BPC-157’s cytoprotection and growth-factor modulation, used in complex injury scenarios. Research applications include multi-tissue regeneration, multi-site injuries, inflammatory control, and functional recovery in musculoskeletal and soft-tissue systems. For research use only - not for human or veterinary use, diagnosis, or treatment.
GLP-1 & Metabolic
A triple agonist at GLP-1, GIP, and glucagon receptors, providing robust multi-hormone modulation of satiety, insulin secretion, lipid metabolism, and energy expenditure. Deployed in advanced models of severe obesity, dyslipidemia, metabolic syndrome, and combination incretin/glucagon strategies to push the limits of pharmacologic weight loss. For research use only - not for human or veterinary use, diagnosis, or treatment.
Healing & Recovery
A branded joint and soft-tissue recovery blend, typically incorporating healing and anti-inflammatory peptides (such as BPC-157, TB-500, KPV, GHK etc, depending on formula). Utilized in models of chronic joint stress, tendon/ligament overload, and long-term soft-tissue wear and tear, where multi-pathway support is desirable. For research use only - not for human or veterinary use, diagnosis, or treatment.
Healing & Recovery
A cosmetic-oriented skin and connective-tissue rejuvenation blend, often including peptides like GHK-Cu and BPC-157 plus supportive cofactors. Used in dermal remodeling, collagen support, scar appearance, skin elasticity, and hair/follicle health research, bridging regenerative and aesthetic outcomes. For research use only - not for human or veterinary use, diagnosis, or treatment.
GLP-1 & Metabolic
A mitochondria-derived peptide that influences AMPK activation, folate–purine pathways, and skeletal muscle substrate use. It is central in studies of insulin resistance, obesity, exercise-mimetic effects, aging, and healthspan, particularly where mitochondrial function and metabolic flexibility are key endpoints.It has been studied for its role in cellular metabolism, with research suggesting it may influence energy balance and stress-response pathways. For research use only - not for human or veterinary use, diagnosis, or treatment.

The 99 Purity Standard
USA-Manufactured. Third-Party Verified.
Every research peptide is synthesized in U.S. facilities under 503A and 503B manufacturing standards, independently verified through third-party analytical testing, and lyophilized under vacuum to preserve molecular stability from batch to bench.
We never rely on manufacturer claims. Every batch is independently tested by accredited U.S. third-party laboratories to confirm minimum 99% purity before it reaches inventory.
503A · 503B Standards
Each research compound is lyophilized (freeze-dried) under vacuum, preserving long-term molecular integrity and structural stability throughout transit and cold storage.
Batch-Tested for Stability
Precision is non-negotiable. We guarantee exact milligram content per vial under 505A-compliant quality systems, removing dosing guesswork from your research.
