What are the components of Lipo B 216 mg/mL?

Lipo B 216 mg/mL contains L-Carnitine (20 mg/mL), L-Arginine (20 mg/mL), L-Methionine (25 mg/mL), Inositol (50 mg/mL), Choline (50 mg/mL), Vitamin B6 (Pyridoxine) (25 mg/mL), Vitamin B5 (Dexpanthenol) (25 mg/mL), Vitamin B12 (1 mg/mL).

How is Peptide Foundry's Lipo B characterized?

Lipo B is a compounded multi-ingredient liquid formulation of amino acids, lipotropic agents, and B-complex vitamins rather than a single peptide. It is prepared to a defined per-mL composition (216 mg/mL combined actives). The HPLC / LAL / ICP-MS purity panel used for single peptide active ingredients does not directly apply to a multi-ingredient liquid blend; quality is assessed against the formulation's compositional specification.

How should Lipo B 216 mg/mL be stored?

Store Lipo B refrigerated (2–8 °C / 36–46 °F), away from direct light, and do not freeze. As a multi-dose liquid, draw with sterile technique and discard if the solution becomes cloudy, discolored, or shows visible particulates.

Does Lipo B 216 mg/mL ship with a Certificate of Analysis?

Lipo B is a compounded liquid formulation; lot-level documentation is provided where available. A Certificate of Analysis is not currently published for this product. Unlike single peptides, it is not characterized by the HPLC / LAL / ICP-MS panel used for peptide active ingredients.

Is Lipo B 216 mg/mL sold for human use?

No. All products sold by Peptide Foundry are strictly for in-vitro research and laboratory use only (RUO). They are not intended for human or animal consumption, therapeutic use, or diagnostic application.

A compounded lipotropic and B-complex research formulation studied in laboratory settings for metabolic and energy pathways

About Lipo B 216 mg/mL

Lipo B is a compounded research formulation combining amino acids (L-Carnitine, L-Arginine, L-Methionine), lipotropic agents (Inositol, Choline), and B-complex vitamins (B6, B5, B12), supplied as a sterile liquid solution for in-vitro research into metabolic and energy pathways.

Lipo B brings together three categories of well-characterized research compounds—amino acids, lipotropic agents, and B-complex vitamins—in a single liquid formulation. The amino acids L-Carnitine, L-Arginine, and L-Methionine have each been studied for distinct metabolic roles, from mitochondrial fatty-acid transport to nitric-oxide signaling and methyl-group donation. The combination is intended to let researchers examine these complementary pathways together rather than in isolation.

The lipotropic components—choline and inositol—anchor the formulation's metabolic focus. In the research literature, choline has been examined as a key methyl donor and a factor in hepatic lipid export via VLDL, while inositol has been studied for its associations with insulin signaling and adipocyte function, including in polycystic-ovary research models. The B-complex vitamins (B6, B5, and B12) are studied as cofactors in amino-acid metabolism, coenzyme-A formation, and the methylation cycle.

Combining these eight ingredients lets researchers investigate fatty-acid oxidation, methylation efficiency, insulin signaling, mitochondrial energy, and nitric-oxide-mediated circulation within a single preparation. Lipo B is supplied as a sterile liquid solution and is intended for research use only.

How Lipo B 216 mg/mL Works

Lipo B combines eight research compounds that have each been studied in laboratory settings for distinct metabolic mechanisms—mitochondrial fatty-acid transport, nitric-oxide signaling, methylation, insulin signaling, hepatic lipid handling, and coenzyme-dependent energy metabolism.

L-Carnitine — Mitochondrial Fat Transport

L-Carnitine has been studied in preclinical models for transporting long-chain fatty acids across the mitochondrial membrane, a step examined in research on β-oxidation and cellular energy production.

L-Arginine — Nitric Oxide & Circulation

L-Arginine is a precursor to nitric oxide and has been investigated in laboratory models for associations with vascular tone, endothelial signaling, and nutrient-delivery pathways.

L-Methionine — Methylation & Glutathione Synthesis

L-Methionine has been studied as a methyl-group donor that converts to S-adenosylmethionine (SAMe), with research examining its role in methylation cycles and glutathione-synthesis pathways.

Inositol — Insulin Signaling

Inositol has been investigated in preclinical and PCOS research models for associations with insulin signaling, adipocyte function, and neurotransmitter-balance pathways.

Choline — Lipotropic & Liver Research

Choline is a key lipotropic agent studied for its role in VLDL formation and hepatic lipid export, as well as its function as an acetylcholine precursor in laboratory models.

B-Complex (B6, B5, B12) — Metabolic Cofactors

The B-complex vitamins have been studied as cofactors in amino-acid metabolism (B6), coenzyme-A formation for fatty-acid processing (B5), and methylation and nucleotide-synthesis cycles (B12) in research models.
