Glp-1TRZ
GLP-1 & Metabolic
A Glp-1TRZ is a dual GIP and GLP-1 receptor agonist used in metabolic research to model powerful incretin effects on insulin secretion, appetite suppression, gastric emptying, and body-weight regulation. Investigators use it to study obesity, type 2 diabetes, visceral fat reduction, and β-cell function, and to compare dual-pathway incretin signaling to single GLP-1 analogs. For research use only - not for human or veterinary use, diagnosis, or treatment.
BPC-157/TB-500
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-3RTA
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.
KLOW
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.
GLOW
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.
MOTS-C
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.
Semax / Selank (Blend)
Cognitive & Nootropic
Semax/Selank 10/10mg is a research-grade dual neuroactive peptide blend developed for laboratory investigations involving melanocortin signaling, GABAergic neurotransmission, neurotrophic factor regulation, intracellular signaling pathways, and peptide pharmacology. Every batch undergoes comprehensive analytical verification to ensure purity, consistency, and reproducibility for advanced neuroscience, receptor biology, and molecular research.

The 99 Purity Standard
ENGINEERED FOR
ABSOLUTE PRECISION.
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.
99.1%+ Verified Purity
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
Lyophilized Stability
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
Exact Milligram Dosing
Precision is non-negotiable. We guarantee exact milligram content per vial under 505A-compliant quality systems, removing dosing guesswork from your research.

Excellent rating on
Kyran Barros Miranda
I had an issue during checkout, but their customer service was excellent. They responded very quickly, were very attentive, and resolved the problem right away by refunding the price difference. Great customer support. Thank you!
Abigail D'Italia
When I was first getting into the peptide world I was nervous and didn't know what to get, where to go or even if I could trust the product. I trusted my gut and ordered from 99 purity 7 months ago and I've been a customer since
Tanner Gauthier
Website is easy to navigate & great customer service! Highly recommend!
