Our products: research peptides, amino acids, and laboratory compounds.

GLP-1 & Metabolic
GLP-1TRZ Spray is a research-use material supplied by Helix Bio as a prepared spray-format solution rather than as a lyophilised solid. The compound it contains, its concentration and its supporting analytical data are recorded in the product documentation and the lot-specific Certificate of Analysis, which are the authoritative record for any given lot. Helix Bio supplies research materials for qualified laboratory and scientific applications. GLP-1TRZ Spray is offered strictly for research use. It is not intended for human or veterinary consumption, ingestion, injection, inhalation, self-administration, cosmetic use, or the diagnosis, treatment, cure or prevention of any disease or condition. The word "Spray" describes the physical presentation of the material and does not indicate a route of administration.

Healing & Recovery
Four molecular entities share one container here, and the smallest of them is the reason the product has its own name. KLOW Blend Spray is Helix Bio's prepared-solution preparation of the KLOW combination — GHK-Cu, a copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine; BPC-157, a synthetic pentadecapeptide; TB-500, a thymosin β4-related material; and KPV, the three-residue C-terminal fragment of α-melanocyte-stimulating hormone. Those first three are the GLOW combination. KPV is the addition, and it is the only compositional difference between the two. Helix Bio supplies this material for qualified laboratory and scientific research. It is not intended for human or veterinary consumption, administration by any route, diagnosis, treatment, or prevention of disease. One thing is worth establishing before anything else on this page: KLOW is a product designation rather than a characterised substance, and published specifications for blends carrying the name do not agree with each other. What a given container holds is settled by its lot documentation, not by its label.

Cognitive & Nootropic
Semax and Selank were built to the same template and are not the same molecule. Each is a synthetic heptapeptide made by taking a short biologically interesting sequence — the ACTH(4-7) fragment in one case, the endogenous tetrapeptide tuftsin in the other — and extending it at the C-terminus with Pro-Gly-Pro. Helix Bio supplies the two together as a single vial-format research material for qualified laboratory work only, not for human or veterinary use. What that material is not is a third compound. This blend contains two separate molecular entities that retain their own sequences, their own molecular weights and their own separate bodies of published research. Nothing in that literature examines the two administered together, and the page below keeps component evidence, combination evidence and Helix product data in three clearly separated layers.

GLP-1 & Metabolic
One oxygen atom is the entire chemical difference between this peptide and the compound it is most often confused with. H Frag is Helix Bio’s designation for hGH Fragment 176-191, the sixteen-residue C-terminal segment of human growth hormone, sequence FLRIVQCRSVEGSCGF, closed by the native Cys182–Cys189 disulfide the parent hormone carries in the same position. Swap the opening phenylalanine for a tyrosine and you have AOD-9604 — a different molecule, with a different registry number and a different evidence base. Supplied here in vial format as a research material for qualified laboratory use. Not intended for human or veterinary consumption, or for the diagnosis, treatment, cure or prevention of any disease.

Cognitive & Nootropic
Dihexa is a peptidomimetic small molecule — C₂₇H₄₄N₄O₅, 504.67 g/mol, CAS 1401708-83-5 — built by capping a tyrosine–isoleucine core with a hexanoyl group at one end and a 6-aminohexanamide at the other. It was developed at Washington State University from angiotensin IV, and the caps were the whole point: they remove the bonds proteases cleave and raise lipophilicity far enough that the compound no longer dissolves in water. Helix Bio supplies it in solid form, which leaves the choice of solvent with the researcher. Research and laboratory use only; not for human or veterinary use, ingestion, injection, or administration by any route.

Nasal Sprays
No two suppliers agree on what Lipo-C contains. The name belongs to compounding-pharmacy practice rather than to chemistry, and formulations sold under it range from four components to eight — with the letter C used variously for choline, for carnitine, and for ascorbic acid depending on who prepared the material. Helix Bio supplies Lipo-C Spray as a prepared multi-component solution for qualified laboratory work. The composition that governs an experiment is the one on the documentation for the lot in hand, not the one a search result attributes to the name. Research and laboratory use only; not intended for human or veterinary consumption, or for administration by any route.

Nasal Sprays
Kisspeptin is not a single peptide. The name covers a group of related fragments produced by proteolytic processing of a precursor encoded by the KISS1 gene — most commonly described as kisspeptin-54, kisspeptin-14, kisspeptin-13 and kisspeptin-10 — all of which share the same C-terminal decapeptide and all of which act at the KISS1R receptor, also known as GPR54. Kisspeptin Spray is Helix Bio’s spray-format preparation supplied for laboratory investigation of that signalling system. Because the forms differ in length, mass and behaviour, the specific fragment supplied in any given lot is a matter for the accompanying documentation rather than the product name. Helix Bio provides research materials for qualified scientific work only. This product is not intended for human or veterinary consumption, self-administration, diagnosis, treatment, or the prevention of any disease.

Nasal Sprays
Two peptides, two molecular identities, one container. BPC-157 / TB-500 Blend Spray pairs BPC-157 — a synthetic 15-residue peptide with the sequence GEPPPGKPADDAGLV — with material supplied under the name TB-500, which the analytical literature associates with an N-terminal-acetylated fragment spanning the actin-binding region of thymosin beta-4. The two components differ substantially in size, and that difference shapes how the blend should be characterised, documented and interpreted in an experimental record. Helix Bio supplies this preparation as a spray-format research material for qualified laboratory and scientific work. It is not intended for human or veterinary consumption, diagnosis, treatment, or prevention of disease, and it is not a treatment product of any kind.

Nasal Sprays
Ask three suppliers what TB-500 is and you can get three different molecules. The name is attached in the marketplace to a seven-residue peptide, to a supposed seventeen-residue peptide, and to the full forty-three-residue thymosin beta-4 protein — substances differing in mass by more than a factor of five. FDA’s bulk drug substances record supplies the definition this page uses: TB-500 is thymosin beta-4, fragment (LKKTETQ), the acetylated heptapeptide corresponding to residues 17 through 23 of the parent protein. Helix Bio supplies TB-500 Spray as a prepared-solution research material for qualified laboratory and scientific applications. It is offered strictly for research use and is not intended for human or veterinary consumption, diagnosis, treatment, or prevention of disease.

Nasal Sprays
Two peptides, two receptor systems, one research material. Tesamorelin + Ipamorelin Blend Spray pairs tesamorelin — a 44-residue analogue of human growth hormone-releasing hormone carrying a trans-3-hexenoyl modification at its N-terminus — with ipamorelin, a five-residue growth hormone secretagogue that acts at the ghrelin receptor GHSR-1a. The two compounds are chemically unrelated and reach the growth hormone axis through separate receptors. Helix Bio supplies the pair as a prepared spray-format research material for qualified laboratory use only; it is not intended for human or veterinary consumption, diagnosis, treatment, or prevention of disease.

Nasal Sprays
5-Amino-1MQ Spray is a research-use liquid formulation of 5-amino-1-methylquinolinium, a synthetic small-molecule inhibitor of nicotinamide N-methyltransferase (NNMT). Despite appearing in peptide catalogues, 5-Amino-1MQ is not a peptide. It is a quinolinium salt with no amino acid sequence, and it works by inhibiting an enzyme rather than by binding a receptor. Published research on the compound is preclinical, drawn from cultured adipocytes, myoblasts, and rodent models. Helix Bio supplies this material for laboratory research only.

Nasal Sprays
Ipamorelin is a synthetic pentapeptide — Aib-His-D-2-Nal-D-Phe-Lys-NH₂ — developed at Novo Nordisk and described in 1998 as the first growth hormone secretagogue whose selectivity for growth hormone release approached that of GHRH itself. It binds the ghrelin receptor, GHS-R1a. Helix Bio supplies it here as a spray-format research material for controlled laboratory work. This product is intended for research and laboratory investigation only. It is not intended for human or veterinary use, ingestion, injection, nasal administration, or any other form of administration, and it is not offered for the diagnosis, treatment, cure or prevention of any disease.

Nasal Sprays
GLP-3RTA is a synthetic 39-residue lipidated peptide — registered under CAS 2381089-83-2 and developed under the code LY-3437943 — engineered to act at three receptors simultaneously: the GIP receptor, the GLP-1 receptor and the glucagon receptor. Helix Bio supplies it here as a prepared spray-format solution for controlled laboratory work. Research and laboratory use only; not for human or veterinary administration, and not a treatment for any condition. One point about the name deserves stating up front, because researchers ask about it. GLP-3RTA is a catalog designation, not a hormone name. There is no hormone called GLP-3, and this compound’s backbone comes from GIP rather than from GLP-1. The section below explains what the designation does and does not mean, and the rest of the page keeps the compound’s clinical development programme carefully separate from anything supplied as a research reagent.

Nasal Sprays
Roughly a sixth of this molecule is not peptide at all. Semaglutide is a 31-residue analogue of glucagon-like peptide-1 carrying a fatty diacid attached to Lys26 through a glutamate and two ethylene-glycol spacers — an engineered side chain that binds albumin and is the reason the molecule persists in circulation for about a week rather than minutes. Helix Bio supplies it, C₁₈₇H₂₉₁N₄₅O₅₉ at 4113.6 g/mol, as a prepared spray solution. This is a research material for qualified laboratory use. It is not a medicine, not a substitute for one, and is not intended for human or veterinary consumption or administration by any route.

Nasal Sprays
Melanotan 1 is the 13-residue α-MSH analogue known in the literature as NDP-MSH, or [Nle⁴,D-Phe⁷]-α-MSH: the native melanocortin sequence with norleucine replacing methionine at position 4 and the phenylalanine at position 7 inverted to its D-enantiomer. Helix Bio supplies it here as a prepared spray-format solution for controlled laboratory work, alongside the lyophilised Melanotan-1 vial listed separately in this catalog. Supplied for research and laboratory purposes only; not intended for human or veterinary use, and not a cosmetic or tanning product. Those two substitutions are what a researcher evaluating this material actually has to verify, and one of them cannot be seen by mass spectrometry. Current product documentation and lot-specific analytical information should be reviewed — with attention to the method used to establish identity — before the material enters an experimental workflow.

Nasal Sprays
Acetyl Octapeptide-3, known commercially as SNAP-8, is a synthetic eight-residue peptide with the sequence Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH₂, reproducing residues 12 to 19 of the N-terminal region of the SNAP-25 protein. It has been examined in peptide chemistry, SNARE-complex research, analytical method development and cosmetic formulation science. This Helix Bio material supplies that peptide as a prepared spray-format solution rather than a lyophilised solid. Helix Bio supplies research materials to qualified laboratory and scientific users. SNAP-8 Spray is offered for research use only. It is not intended for human or veterinary consumption, cosmetic application, self-administration, or the diagnosis, treatment, cure or prevention of any disease.

Nasal Sprays
Long R3 IGF-1 — written IGF-1 LR3 across most research catalogues — is an 83-residue recombinant analogue of human insulin-like growth factor 1, built by two deliberate changes to the 70-residue native sequence: a thirteen-amino-acid extension on the N-terminus and an arginine substituted for glutamate at position three. Together those modifications substantially reduce the molecule’s affinity for IGF binding proteins, which is why it became a standard supplement in serum-free mammalian cell culture. IGF-1 LR3 Spray is Helix Bio’s spray-format preparation of that analogue, supplied as a research material. Helix Bio provides laboratory materials for qualified scientific work only. This product is not intended for human or veterinary consumption, self-administration, diagnosis, treatment, or the prevention of any disease. Researchers should review the current lot documentation before incorporating the material into any experimental workflow.

Nasal Sprays
Human chorionic gonadotropin is not a peptide in the sense that most of this catalogue is. It is a heterodimeric glycoprotein hormone — two different chains, held together without a covalent bond, with close to a third of the molecule’s mass made up of attached carbohydrate. That structure governs how the material behaves, how it is characterised, and what can reasonably be concluded from work done with it. HCG Spray is Helix Bio’s spray-format presentation of this hormone, supplied for qualified laboratory and scientific investigation. Helix Bio supplies HCG Spray strictly as a research material. It is not intended for human or veterinary use, ingestion, injection, nasal administration, or any other form of administration, and it is not offered as a medication, a dietary supplement or a weight-management product. Lot-specific documentation should be reviewed before the material enters any experimental workflow.

Nasal Sprays
Three separately characterised molecules share one bottle here, and only two of them are peptides in the ordinary sense. Glow Blend Spray is Helix Bio’s spray-format preparation of the GLOW combination — GHK-Cu, a copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, together with the synthetic pentadecapeptide BPC-157 and a thymosin β4-related material supplied as TB-500. Each has its own literature, its own molecular identity and its own analytical requirements. Helix Bio supplies this material for qualified laboratory and scientific research. It is not intended for human or veterinary consumption, administration by any route, diagnosis, treatment, or prevention of disease.

Two of the four residues in SS-31 are not what a peptide chemist would expect. The sequence — D-Arg–Dmt–Lys–Phe–NH₂ — pairs a D-configured arginine with 2′,6′-dimethyltyrosine, a non-proteinogenic residue, in an alternating cationic-aromatic arrangement that gives the molecule a net charge of +3 at neutral pH and an affinity for cardiolipin, the anionic phospholipid of the inner mitochondrial membrane. That combination is why SS-31 has become a reference compound in mitochondrial membrane research. Helix Bio supplies SS-31 Spray as a spray-format research material for qualified laboratory and scientific work. It is not intended for human or veterinary consumption, diagnosis, treatment, or prevention of disease, and it is not a treatment product of any kind.

Nasal Sprays
Sermorelin Spray is a research-use peptide preparation containing sermorelin, a synthetic 29-amino-acid peptide corresponding to the N-terminal fragment of human growth hormone-releasing hormone and identified in scientific literature as GHRH(1-29)-NH₂. Sermorelin acts at the growth hormone-releasing hormone receptor (GHRHR) and has a long published record in endocrine, receptor-pharmacology and peptide-chemistry research. Helix Bio supplies research materials for qualified laboratory and scientific applications. Sermorelin Spray is offered strictly for research use and is not intended for human or veterinary consumption, diagnosis, treatment, or prevention of disease.

Nasal Sprays
H Frag Spray is a research-use preparation of hGH Fragment 176-191, the sixteen-residue peptide corresponding to the C-terminal end of the 191-amino-acid human growth hormone sequence. The fragment begins at phenylalanine and carries an internal disulfide bridge between its two cysteine residues. It is a distinct molecule from AOD9604, which substitutes tyrosine at the first position and has a separate analytical profile and a separate evidence base.Helix Bio supplies this material for qualified laboratory and scientific applications. H Frag Spray is offered strictly for research use and is not intended for human or veterinary consumption, or for the diagnosis, treatment, cure or prevention of any disease.

Nasal Sprays
A 23-membered lactam ring is what separates Melanotan II from every linear melanocortin peptide it is related to. Bridging the Asp⁵ side chain to the ε-amino group of Lys¹⁰ locks a seven-residue fragment of α-MSH into a fixed conformation, and Helix Bio supplies that molecule — C₅₀H₆₉N₁₅O₉, 1024.18 g/mol, CAS 121062-08-6 — as a prepared spray solution for laboratory work. The material is intended for qualified scientific research only. It is not for human or veterinary consumption, administration by any route, tanning, cosmetic use, diagnosis, treatment, or prevention of disease.

Nasal Sprays
CJC-1295 / Ipamorelin Spray is a research-use peptide blend formulation combining two distinct synthetic peptides: CJC-1295, a growth hormone-releasing hormone (GHRH) analogue, and Ipamorelin, a selective ghrelin-receptor (GHSR-1a) agonist. Each component is associated with published research into a separate branch of growth-hormone-axis signaling, and both are supplied together in this Spray formulation for laboratory investigation. Helix Bio supplies research materials for qualified laboratory and scientific applications. CJC-1295 / Ipamorelin Spray is offered strictly for research use and is not intended for human or veterinary consumption, diagnosis, treatment, or prevention of disease.
