Lactoferricin B is bovine lactoferrin's antimicrobial fragment with 297 PubMed papers and zero human trials. Preclinical data shows broad-spectrum membrane-disrupting activity against bacteria, fungi, and cancer cell lines. All dosing is speculative. This is a research compound with a real scientific foundation but no clinical translation yet.

LfcinB typically comes as lyophilized powder in 2 mg or 5 mg vials from research-grade suppliers. This is not a mainstream peptide vendor product; expect to source from biochemical research suppliers like NovoProLabs (~$85/mg for a 5 mg vial) or AnaSpec ($150-300+/mg). Reconstitution math for a 2 mg vial: add 2.0 mL bacteriostatic water. That gives you 1 mcg per mcL. A 50 mcg beginner dose equals 50 mcL, which is 5 units on a U-100 insulin syringe. For 100 mcg, draw 10 units. For 200 mcg, draw 20 units. Don't use saline or high-ionic-strength buffers for reconstitution. LfcinB aggregates and turns turbid at neutral pH in those solutions; stick with sterile water or low-concentration bacteriostatic water. Check the Certificate of Analysis for two things before using any vial: HPLC purity above 95% and mass spectrometry confirming the correct molecular weight of 3124 Da. The disulfide bond between Cys19 and Cys36 must be confirmed intact. Linear (reduced) LfcinB has substantially weaker antimicrobial activity.

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.
