Super Human Blend is a multi-ingredient research solution of amino acids and L-carnitine, supplied in a 10 mL sterile liquid vial and stored refrigerated. It contains no peptides. The product specification lists:
L-carnitine 220 mg
L-citrulline 120 mg
L-arginine 110 mg
L-ornithine 110 mg
L-lysine 70 mg
L-proline 60 mg
Taurine 60 mg
L-glutamine 40 mg
What the components have in common
Arginine, ornithine and citrulline are linked through the urea cycle and arginine metabolism, which outside the liver also feed the synthesis of nitric oxide, polyamines, proline and glutamate.[1] L-carnitine carries long-chain fatty acids into mitochondria for β-oxidation.[4] Taurine, glutamine and proline have their own roles in cell volume regulation, immune cell metabolism and collagen.[5][6][7]
Evidence for the combination
We found no published study of this specific combination. Each ingredient has its own literature, summarized below; this formulation is not an approved medicine.

Quality & Storage
≥98% purity. Sterile Liquid Vial. Storage: 2-8°C. For research purposes only.
Mechanism of Action
Arginine, citrulline and ornithine
Urea cycle enzymes: the complete urea cycle is expressed in the liver and, to a small degree, in enterocytes; several of its enzymes are also expressed in other tissues, where they make nitric oxide, polyamines, proline and glutamate.[1]
Nitric oxide: all three nitric oxide synthase isoforms use L-arginine and oxygen as substrates.[2]
Citrulline as an arginine source: oral L-arginine is extensively eliminated by intestinal arginase before reaching the circulation, whereas L-citrulline is readily absorbed and partly converted to L-arginine; in a crossover study in healthy volunteers, citrulline raised plasma arginine more effectively than arginine itself.[3]
L-carnitine
Carnitine is essential for transferring long-chain fatty acids across the inner mitochondrial membrane. Cells accumulate it through the high-affinity transporter OCTN2, and defects in this transporter cause primary carnitine deficiency.[4] L-carnitine is also available on its own as L-Carnitine.
Taurine, glutamine, proline and lysine
Taurine: an organic osmolyte involved in cell volume regulation, bile salt formation and intracellular calcium; it is one of the few amino acids not built into proteins.[5] Chemically it is 2-aminoethanesulfonic acid, which has no chiral center, so it has no L or D form.[8]
Glutamine: the most abundant amino acid in the body and a major fuel for lymphocytes, macrophages and neutrophils.[7]
Proline: glycine, proline and hydroxyproline make up 57% of the amino acids in collagen, and mammals can synthesize proline from arginine.[6]
Lysine: an essential amino acid, included as a protein building block.
Research Applications
Laboratory research applications
Nitric oxide and arginine metabolism: arginine availability, citrulline recycling and NOS activity.[2][3]
Urea cycle and polyamine studies: ornithine and arginine metabolism in hepatic and non-hepatic cells.[1]
Mitochondrial fatty acid oxidation: carnitine-dependent transport in cell models.[4]
Cell culture supplementation: glutamine-dependent immune cell function and proline supply for collagen-producing cells.[6][7]
This product is sold for laboratory research only and is not intended for human or veterinary use.
Storage & Handling Guidelines
Proper storage and handling are essential to maintain peptide integrity and ensure reliable research results. All Pepitiva Biolabs peptides are supplied as lyophilized (freeze-dried) powder, which provides excellent long-term stability when stored correctly. Store lyophilized peptides at -20°C for long-term storage or 2-8°C for short-term use. Once reconstituted, peptide solutions should be stored at 2-8°C and used within the timeframe specified in the product documentation. Always use sterile bacteriostatic water for reconstitution and handle peptides in a clean laboratory environment to prevent contamination. Avoid repeated freeze-thaw cycles, as thermal stress can cause peptide degradation and loss of biological activity.
Quality Control & Certification
This product is manufactured under strict quality control protocols and has been verified through comprehensive analytical testing. Each batch undergoes reverse-phase HPLC analysis for purity determination and electrospray ionization mass spectrometry (ESI-MS) for molecular identity confirmation. A detailed Certificate of Analysis (COA) is available for download, documenting purity percentage, molecular weight verification, appearance, and recommended storage conditions. Pepitiva Biolabs maintains batch-level traceability from synthesis through delivery, ensuring complete transparency and quality assurance for your research.
Frequently Asked Questions
What is in the Super Human Blend?
L-carnitine 220 mg, L-citrulline 120 mg, L-arginine 110 mg, L-ornithine 110 mg, L-lysine 70 mg, L-proline 60 mg, taurine 60 mg and L-glutamine 40 mg, as listed in the product specification, in a 10 mL sterile solution.
Is the Super Human Blend a peptide?
No. It is a solution of free amino acids and L-carnitine. None of the ingredients is a peptide.
Has this combination been studied?
We found no published study of this specific combination. Each ingredient has its own literature, for example on arginine and citrulline in nitric oxide metabolism and on carnitine in fatty acid transport.
Why does the blend contain both arginine and citrulline?
They are interconverted in arginine metabolism. In a study in healthy volunteers, oral citrulline raised plasma arginine more effectively than oral arginine, which is largely broken down by intestinal arginase.
What does L-carnitine do?
It carries long-chain fatty acids across the inner mitochondrial membrane so they can be oxidized. See L-Carnitine.
How should the Super Human Blend be stored?
Keep the vial refrigerated at 2 to 8 °C.
Is this product approved for human use?
No. This product is intended exclusively for in vitro scientific research and laboratory use. It is not approved for human or veterinary use, not intended for diagnostic or therapeutic purposes, and should not be administered to humans or animals under any circumstances.
How do I reconstitute this peptide?
Add sterile bacteriostatic water slowly to the vial, directing the stream against the glass wall rather than directly onto the lyophilized powder. Gently swirl the vial until the powder is fully dissolved — do not shake vigorously. The recommended reconstitution volume depends on your desired concentration. Refer to the product documentation for specific guidance.
Can I get a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis is included with every order and is also available for download from the product page. The COA documents HPLC purity, mass spectrometry identity confirmation, batch number, production date, and storage recommendations.
