LL-37 dosage by administration route

LL-37 topical dosage

Topical venous-ulcer protocols use 0.5 or 1.6 mg/mL LL-37 solution twice weekly for 13 weeks. An application volume of 25 microliters per cm² of ulcer gives 12.5 or 40 mcg/cm², respectively, alongside wound dressings and compression care.[1]

LL-37 is a cathelicidin peptide involved in antimicrobial defense and barrier signaling. Local wound formulations target a different exposure pattern from systemic injections.[2][3][4][5]

LL-37 injectable dosage

Reported injectable protocols use 500 mcg–1.6 mg per administration, 1-2 times daily for 2-4 weeks. An additional reported subcutaneous range is 100–300 mcg once daily for 2–4 weeks. This is lower than the other reported injectable range above and is not a dose-equivalence rule for topical wound products.[6][3][2][8]

Frequency and timing

Use injections in the morning or evening. Apply topical products during dressing changes.[2]

Cycle length and breaks

Topical: 13 weeks. Injectable: 2-4 weeks. A standard break interval between courses is not established.[1][6][3][2]

LL-37 safety and side effects

Approval and product quality

LL-37 is not an FDA-approved drug.[6][7]

Side effects and long-term safety

Topical use is the clearest local-tolerance context. Injectable LL-37 lacks a mature human pharmacokinetic and long-term systemic safety base. Topical LL-37 safety centers on local irritation and wound-care context. Injectable or systemic exposure is a different risk category, with added immune-activation, sterility, product-quality, and unknown exposure concerns.[2][6][7]

Route-specific dosing limits

Immune-active peptides need extra caution when infection, autoimmune disease, or open wounds are involved. Additional schedules attributed to Everything Peptide are reported patterns; citing research does not make these schedules clinically established or approved product instructions.[5][3][8]

Common LL-37 dosage questions

Can LL-37 doses be transferred between routes?

No. Each route and formulation has its own exposure and administration requirements. Use the dose information for the exact presentation rather than copying a tablet, injection or local-product amount to another route.[2][3][6][7]

What dosage is listed for LL-37?

Topical venous-ulcer protocols use 0.5 or 1.6 mg/mL LL-37 solution twice weekly for 13 weeks.[1]

Does LL-37 have a standard cycle or break interval?

Topical: 13 weeks. Injectable: 2-4 weeks. A standard break interval between courses is not established.[1][6][3][2]
