Injection Guide
Most potent human beta-defensin (45 amino acids) with unique salt-insensitive antimicrobial activity — kills MRSA at MIC 0.5-1.0 μg/mL regardless of salt concentration, disrupts biofilms at 4-8 μg/mL, and retains full bactericidal function even without its disulfide bonds — representing a next-generation antimicrobial peptide template for combating antibiotic resistance
Route
Topical application (research/wound care)
Sites
1 recommended
Frequency
As needed
Preparation
Defensin (HBD-3) in its prescribed form
Clean, dry storage container
Measuring device if applicable (oral syringe, measuring cup)
Calendar or reminder app for dosing schedule
Pro Tip
Prepare all supplies on a clean surface before you begin. Having everything ready makes the process smoother and more sterile.
Mixing
Wash your hands thoroughly with soap and water. Gather all supplies on a clean, flat surface.
Remove the plastic cap from the peptide vial and wipe the rubber stopper with an alcohol swab. Let it air dry.
Draw the appropriate amount of bacteriostatic water into a sterile syringe.
Insert the needle into the vial at an angle, aiming at the inside wall of the vial. Slowly push the plunger to let the water trickle down the glass wall -- do NOT squirt directly onto the powder.
Once all water is added, gently swirl the vial in a slow circular motion. Never shake the vial, as this can damage the peptide bonds.
Continue swirling until the powder is completely dissolved and the solution is clear. If particles remain, let the vial sit for a few minutes and swirl again.
Label the vial with the date of reconstitution, the peptide name, and the concentration (e.g. 250mcg per 0.1mL).
Example Calculation
Defensin (HBD-3) comes in pre-measured doses or forms. Follow the exact dosing instructions on your prescription label. No reconstitution or mixing is typically required for this formulation.
Dose Calculation
Use Defensin (HBD-3) exactly as prescribed. Each unit contains the labeled amount. Your healthcare provider will determine the appropriate dose based on your individual needs and response.
Pro Tip
Always add the bacteriostatic water slowly, letting it run down the side of the vial. Never shake the vial -- swirl gently to avoid damaging the peptide.
Location
Site 01
Not applicable—this is not an injectable formulation
Follow your provider's instructions for this injection site. Rotate sites regularly to prevent tissue damage.
Rotate between 1 sites to prevent tissue buildup and ensure consistent absorption.
Pro Tip
Rotate your injection sites with each dose to prevent lipohypertrophy (buildup of fatty tissue). Keep a simple log of where you last injected.
Step by Step
Follow the specific administration instructions for your Defensin (HBD-3) formulation
Take or apply as directed by your healthcare provider
Store properly between uses according to package instructions
Pro Tip
This peptide uses defensin (hbd-3) is administered topical application (research/wound care)—no injection required. Inject at a 90 degree angle into the muscle. Aspirate before injecting to ensure you haven't hit a blood vessel.
Timing
Optimal Timing
Best time
Apply Defensin (HBD-3) to clean, dry skin. For best results, use consistently at the same time(s) each day. Evening application is often preferred to allow overnight absorption, unless otherwise directed.
With food?
As a topical product, Defensin (HBD-3) is not affected by food intake. Apply to clean skin and allow adequate absorption time before covering the area.
Stacking notes
Defensin (HBD-3) should be used as directed by your healthcare provider. If combining with other medications or supplements, discuss potential interactions with your provider. Avoid combining with compounds that have overlapping mechanisms unless specifically guided by a medical professional.
Sample Daily Schedule
As prescribed (varies by protocol)

Maintain a consistent schedule for optimal results with Defensin (HBD-3). Set reminders if needed. If you miss a dose, follow your healthcare provider's instructions—do not double up on doses to compensate.
Dosing Tiers
Dose
1-5 μg/mL topical or research application
Frequency
Protocol-dependent
Duration
As defined by research protocol
Effective antimicrobial concentration against MRSA at the low end of this range (MIC 0.5-1.0 μg/mL). HBD-3's extraordinary potency means low concentrations are sufficient for gram-positive coverage. All dosing reflects research and preclinical settings — no established clinical protocols exist for exogenous HBD-3 application.
Dose
5-15 μg/mL topical application
Frequency
Once or twice daily in research settings
Duration
Research protocol-dependent (typically 1-4 weeks)
Provides broad-spectrum antimicrobial coverage against gram-positive bacteria, gram-negative bacteria, and fungi. Covers MIC requirements for most target pathogens. Effective anti-biofilm activity begins at the higher end of this range. Full activity maintained regardless of wound fluid salt concentration.
Dose
15-50 μg/mL topical application
Frequency
Once daily in research settings
Duration
Research protocol-dependent
Provides robust anti-biofilm activity (MRSA biofilm disruption at 4-8 μg/mL) with significant margin above MICs for all major target pathogens. At these concentrations, combined antimicrobial killing, biofilm disruption, and immune cell chemotaxis are all maximally active. Monitor for any cytotoxicity at the high end — therapeutic window remains wide.
Preservation
Before Mixing
Store Defensin (HBD-3) in the refrigerator at 36-46°F (2-8°C) in its original packaging. Protect from light and moisture. Do not freeze. Check the expiration date before use. Some formulations may be stored at room temperature for limited periods—check your specific product labeling.
After Mixing
Once reconstituted, Defensin (HBD-3) should be kept refrigerated at 36-46°F (2-8°C) and used within the timeframe specified on your product labeling (typically 14-28 days). Label the vial with the reconstitution date. Do not use if the solution appears cloudy, discolored, or contains particles.
Shelf Life After Mixing
7 days refrigerated (reconstituted); lyophilized powder stable for 2+ years at -20°C
Signs of Degradation
Discard the vial immediately if you notice any of these:
Solution appears cloudy, discolored, or contains visible particles (should be clear)
Product has been exposed to temperatures outside the recommended storage range
Product has been frozen (unless specifically designed for freeze-thaw stability)
Expiration date has passed or reconstituted solution has exceeded its use-by date
Unusual odor, color change, or visible contamination
Important
When to Stop
Severe or worsening side effects that don't improve with dose adjustment or supportive care
Signs of an allergic reaction—rash, hives, swelling, or difficulty breathing
Your healthcare provider recommends discontinuation based on your clinical response
Development of any new medical condition that may be contraindicated with Defensin (HBD-3)
Pregnancy or planning to become pregnant (unless specifically approved for use during pregnancy)
Abnormal lab results or clinical markers that suggest adverse effects
Defensin (HBD-3) should only be started, adjusted, or discontinued under medical supervision. This information is for educational purposes only and does not replace professional medical advice. Never stop a prescribed treatment without consulting your healthcare provider first, as abrupt discontinuation may have consequences.
