Quickstart Highlights
Chonluten is a short bioregulatory tripeptide (Glu‑Asp‑Gly) studied for its effects on bronchopulmonary tissue and inflammatory pathways in monocyte/macrophage cell models[1]. As a small peptide with poor oral stability, subcutaneous injection is the indicated parenteral route[2]. This educational protocol presents a once‑daily subcutaneous approach using a practical dilution for clear insulin‑syringe measurements.
- Reconstitute: Add 3.0 mL bacteriostatic water → 6.67 mg/mL concentration.
- Typical daily range: 250–4,000 mcg once daily (gradual titration over 8–16 weeks).
- Easy measuring: At 6.67 mg/mL, 1 unit = 0.01 mL ≈ 66.67 mcg on a U‑100 insulin syringe.
- Storage: Lyophilized: refrigerate at 4 °C (39.2 °F) short‑term or freeze at −20 °C (−4 °F) long‑term; after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.

Educational guide for reconstitution and daily dosing
Standard / Gradual Approach (3 mL = 6.67 mg/mL)
| Week | Daily Dose (mcg) | Units (per injection) (mL) |
|---|---|---|
| Weeks 1–2 | 250 mcg (0.25 mg) | 3.75 units (0.0375 mL) |
| Weeks 3–4 | 500 mcg (0.5 mg) | 7.5 units (0.075 mL) |
| Weeks 5–6 | 1,000 mcg (1 mg) | 15 units (0.15 mL) |
| Weeks 7–8 | 1,500 mcg (1.5 mg) | 22.5 units (0.225 mL) |
| Weeks 9–10 | 2,000 mcg (2 mg) | 30 units (0.30 mL) |
| Weeks 11–12 | 3,000 mcg (3 mg) | 45 units (0.45 mL) |
| Weeks 13–14 | 4,000 mcg (4 mg) | 60 units (0.60 mL) |
| Weeks 15–16 | 4,000 mcg (4 mg) | 60 units (0.60 mL) |
Frequency: Inject once daily subcutaneously. For ≤10‑unit (≤0.10 mL) administrations during Weeks 1–4, consider 30‑ or 50‑unit insulin syringes for improved readability.
Reconstitution steps:
- Draw 3.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming.
- Gently swirl/roll until dissolved (do not shake).
- Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

Protocol Overview
Concise summary of the once‑daily regimen.
- Goal: Support bronchopulmonary tissue function and modulate inflammatory pathways[1].
- Schedule: Daily subcutaneous injections for 8–16 weeks with gradual titration.
- Dose Range: 250–4,000 mcg daily with incremental increases every 1–2 weeks.
- Reconstitution: 3.0 mL per 20 mg vial (6.67 mg/mL) for accurate unit measurements.
- Storage: Lyophilized refrigerated or frozen; reconstituted refrigerated; avoid repeated freeze–thaw.
Dosing Protocol
Suggested daily titration approach.
- Start: 250 mcg daily; increase by 250–500 mcg every 1–2 weeks as tolerated.
- Target: Up to 4,000 mcg daily by Weeks 13–16.
- Frequency: Once per day (subcutaneous).
- Cycle Length: 8–16 weeks; shorter durations (8–12 weeks) acceptable.
- Timing: Any consistent time; rotate injection sites.
Storage Instructions
Proper storage preserves peptide quality[3].
- Lyophilized (short‑term): Refrigerate at 4 °C (39.2 °F) in dry, dark conditions.
- Lyophilized (long‑term): Store at −20 °C (−4 °F) or colder; minimize moisture exposure.
- Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within days to weeks and avoid freeze–thaw.
- Allow vials to reach room temperature before opening to reduce condensation uptake.
Important Notes
Practical considerations for consistency and safety.
- Use new sterile insulin syringes; dispose in a sharps container[6].
- Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation.
- Inject slowly; wait a few seconds before withdrawing the needle.
- Document daily dose and site rotation to maintain consistency.
- For initial low‑volume doses (≤10 units), use 30‑ or 50‑unit insulin syringes for improved accuracy.
How This Works
Chonluten (Glu‑Asp‑Gly) is a short bioregulatory peptide studied within the Khavinson peptide bioregulator framework targeting bronchopulmonary tissues[1]. In vitro research using monocyte/macrophage (THP‑1) cell models indicates Chonluten may modulate proliferative activity and inflammatory pathways at concentrations in the nanomolar range[1]. Short peptides such as Chonluten typically exhibit poor oral bioavailability due to enzymatic degradation and limited mucosal permeability, supporting subcutaneous administration as the preferred route[2][5].
Potential Benefits & Side Effects
Observations from preclinical literature.
- May support bronchopulmonary tissue function and respiratory cell regulation based on bioregulator peptide research[1].
- Cell‑culture studies suggest modulation of inflammatory and proliferative pathways in monocyte/macrophage models[1].
- Short peptides in this class generally show favorable tolerability profiles in preclinical settings[5].
- Occasional mild injection‑site reactions (redness/itch) may occur with subcutaneous administration.
Lifestyle Factors
Complementary strategies for respiratory and general wellness.
- Maintain a balanced diet rich in antioxidants to support respiratory tissue health.
- Engage in regular aerobic activity appropriate to fitness level.
- Prioritize sleep and stress management to support immune function and recovery.
- Avoid smoking and minimize exposure to respiratory irritants.
Injection Technique
- Clean the vial stopper and skin with alcohol; allow to dry.
- Pinch a skinfold; insert the needle at 45° into subcutaneous tissue using a 25–27 gauge, ⅝‑inch needle[4].
- Do not aspirate for subcutaneous injections; inject slowly and steadily[4].
- Rotate sites systematically (abdomen, thighs, upper arms) to avoid lipohypertrophy[8].
