How many units of Lactoferricin B (LfcinB) should I draw?

It depends on your vial size, BAC water, and dose. For a 2mg vial with 2mL BAC water, a beginner dose of 50mcg is typically 5 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to Lactoferricin B (LfcinB)?

The standard amount is 2mL of bacteriostatic water for a 2mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a Lactoferricin B (LfcinB) vial last?

At a beginner dose of 50mcg daily, a 2mg vial lasts about 40 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for Lactoferricin B (LfcinB)?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

Lactoferricin B (LfcinB) Pharmacokinetics

Pharmacokinetics — Active Dose Over Time

t½ = ~2-4 hours (estimated; rapid proteolytic degradation in vivo)

After 1 half-life (3h): 50% remainsAfter 2 half-lives (6h): 25% remainsAfter 3 half-lives (9h): 12.5% remains

At a 100mcg dose: 50% = 50mcg remaining after 3h. Recommended frequency: Daily.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

Note: Lactoferricin B (LfcinB) is a 25-amino-acid cationic antimicrobial peptide (residues 17-41 of bovine lactoferrin) generated by pepsin cleavage. It contains an amphipathic beta-sheet stabilized by a single disulfide bond (Cys19-Cys36) and carries a net charge of approximately +8 at physiological pH. LfcinB demonstrates broader and more potent antimicrobial activity than its parent protein lactoferrin. It has been studied extensively for its direct membrane-disrupting mechanism against bacteria, fungi, and parasites, as well as its immunomodulatory and antitumor properties. Research use only — not approved for clinical use.

About Lactoferricin B (LfcinB)

Lactoferricin B is a 25-residue antimicrobial peptide (FKCRRWQWRMKKLGAPSITCVRRAF) derived from the N-terminal region of bovine lactoferrin through pepsin hydrolysis. First isolated and characterized in 1992 by Bellamy et al., it represents one of the most studied naturally derived antimicrobial peptides. The peptide adopts a twisted beta-sheet conformation in solution, stabilized by an intramolecular disulfide bridge. Its high cationic charge and amphipathic structure enable direct interaction with negatively charged microbial membranes, causing membrane permeabilization and cell death. Beyond antimicrobial activity, LfcinB exerts immunomodulatory effects by promoting macrophage and NK cell activation, and demonstrates selective cytotoxicity against cancer cell lines while sparing normal cells. These multifunctional properties have made it a subject of intense research in antimicrobial defense, cancer biology, and immune modulation.
