Tesamorelin / Ipamorelin
Tesamorelin / Ipamorelin is a research-grade dual growth hormone secretagogue blend combining a GHRH analog (Tesamorelin) with a selective GHSR-1a agonist (Ipamorelin) into a single lyophilized preparation. This combination targets the somatotropic axis through two complementary receptor pathways, enabling research into dual-mechanism GH secretion. Each component is independently verified to ≥99% purity by third-party HPLC before co-lyophilization. Research Use Only.
TB-500
TB-500 is a synthetic peptide fragment of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino-acid protein involved in cell migration, angiogenesis, and tissue repair signaling. TB-500 represents the active region of Tβ4 responsible for actin-binding and cell motility properties studied in preclinical research. Each batch is verified to ≥99% purity by third-party HPLC. Research Use Only.
Sermorelin
Sermorelin is a synthetic peptide corresponding to the first 29 amino acids of endogenous Growth Hormone Releasing Hormone (GHRH 1-29). It is the biologically active fragment of the full 44-amino-acid GHRH sequence and acts at pituitary GHRH receptors (GHRHR) to stimulate growth hormone secretion. Sermorelin is one of the most established GHRH analogs in endocrine research literature. Each batch is verified to ≥99% purity by third-party HPLC. Research Use Only.
Semax / Selank
Semax / Selank is a research-grade dual nootropic neuropeptide blend combining two of the most studied neuropeptides in cognitive neuroscience research. Semax (ACTH 4-7 analog) and Selank (tuftsin analog) target distinct but complementary neural signaling pathways — BDNF modulation and GABAergic neurotransmission respectively. Each component is independently synthesized and verified to ≥99% purity by third-party HPLC before co-lyophilization. Research Use Only.
Oxytocin
Oxytocin is a cyclic nonapeptide (Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH₂) produced endogenously in the hypothalamus and one of the most studied neuropeptides in behavioral neuroscience and neuroendocrine research. It is studied for its roles in social bonding, stress response regulation, and reproductive biology in preclinical models. Each batch is verified to ≥99% purity by third-party HPLC. Research Use Only.
Melanotan I
Melanotan I (also known as Afamelanotide) is a synthetic linear tridecapeptide analog of alpha-melanocyte stimulating hormone (α-MSH) with greater selectivity for the MC1R melanocortin receptor compared to MT-2. It is studied in preclinical research for MC1R-specific pigmentation biology and melanogenesis pathway investigation. Each batch is verified to ≥99% purity by third-party HPLC. Research Use Only.
LL-37
LL-37 is the only human cathelicidin antimicrobial peptide, a 37-amino-acid peptide derived from the C-terminal domain of human cathelicidin precursor protein hCAP18. It is one of the most studied host defense peptides in innate immunity research, with published studies examining its antimicrobial, immunomodulatory, and wound healing properties. Each batch is verified to ≥99% purity by third-party HPLC. Research Use Only.
KPV
KPV is a naturally occurring tripeptide (Lys-Pro-Val) representing the C-terminal fragment of alpha-melanocyte stimulating hormone (α-MSH). It is studied in preclinical research for its proposed anti-inflammatory properties, with investigations examining its effects on NF-κB signaling, inflammatory cytokine modulation, and mucosal barrier integrity in cell culture and animal models. Each batch is verified to ≥99% purity by third-party HPLC. Research Use Only.
Eight Research Focuses: Shop by Category
From bioregulators and growth factors to metabolic and recovery compounds, each category is stocked with research peptides meeting our strict 99%+ purity standard. Every product ships with an independently verified COA.
Considered Compounds for Considered Research.
We synthesize ultra-pure research peptides using advanced solid-phase peptide synthesis (SPPS) in US-based, ISO-certified facilities. Every compound undergoes independent third-party LC-MS and HPLC analysis to verify both molecular identity and ≥99% purity before it reaches your bench. No overseas raw powders. No shortcuts. Just verifiable science.
≥99% HPLC Purity — Every Batch, No Exceptions
High-Performance Liquid Chromatography (HPLC) testing is performed on every production batch. Any sample failing to meet our strict 99% purity threshold is immediately discarded — never sold.
LC-MS Verified Peptide Identity
Mass spectrometry (LC-MS) confirms the exact molecular weight and identity of every compound we ship. You receive the peptide on the label, exactly as described.
COA with Every Order — Full Transparency
Every order ships with a lot-specific Certificate of Analysis (COA) traceable to its independent test results. Our full COA library is publicly accessible at any time.
The Looksmaxxing Standard: Why Purity Matters
Purity is not a marketing claim — it is a measurable, verifiable fact. Impure compounds produce unreliable research results. We operate at the intersection of aesthetic science and analytical chemistry so that every batch you receive is exactly what it claims to be.
US-Based Synthesis — Zero Overseas Powders
99%+ Purity Floor — Any Batch Below This Gets Discarded
Cold-Chain Logistics — Molecular Integrity, Guaranteed
Every compound is synthesized in US-based, ISO-certified peptide laboratories using closed-loop solid-phase peptide synthesis (SPPS). We do not purchase raw, untested powders from overseas suppliers or third-party bulk brokers. Our closed-loop supply chain ensures complete molecular traceability from synthesis to shipping.

99%+ Purity Floor — Any Batch Below This Gets Discarded
We enforce a non-negotiable 99% purity minimum across our entire catalog. Every single batch is independently tested by third-party laboratories using both HPLC chromatography and LC-MS mass spectrometry. If a batch fails to meet this threshold — for any reason — it is discarded immediately and never fulfilled.
Cold-Chain Logistics — Molecular Integrity, Guaranteed
Peptides are structurally fragile molecules. Thermal degradation begins at room temperature and accelerates over time. We store all inventory in climate-controlled, medical-grade refrigeration and ship using validated cold-chain packaging specifically designed to maintain peptide integrity from our facility to your bench — regardless of transit conditions.
Verified Purity.
Every Single Batch.
Third-party purity verification is the cornerstone of research-grade compounds. Every vial we ship carries an independently verified COA that proves what is inside — not what we claim is inside. Here is exactly what we test for, and why it matters.
≥99% HPLC Purity
Stringent chromatographic isolation for every compound — verified before any order ships.
Mass Spectrometry (LC-MS)
Exact molecular weight verification confirms you are receiving the compound on the label.
Endotoxin-Free
Limulus Amebocyte Lysate (LAL) testing confirms endotoxin levels below research-safe thresholds.
