At a glance

A short-acting GHRH-related research record that requires precise naming.

This profile separates the compound’s scientific background from specification-specific preparation and source schedules. Begin with the research findings and limitations, then select the formulation you want to examine.

How it works

The “no DAC” name is commonly associated with modified GRF(1–29). It refers to a different exposure profile from the albumin-binding DAC compound. Verify which molecule a cited paper actually studied.[1][2][3]

Potential benefits & side effects

Interpret each outcome in the context of the study population, formulation and evidence type. Research findings do not establish a personal treatment outcome.

Potential benefits & research findings

Growth hormone signaling is the central research theme. Results for long-acting CJC-1295 cannot simply be assigned to a no-DAC formulation.[2][5][6]

Read the original publications to see the measured endpoints, comparator, duration and uncertainty. Mechanistic plausibility and a favorable experimental result are different from demonstrated clinical benefit.

Side effects & evidence limitations

Interpret the reported adverse effects together with the study population, route and observation period. Small or short studies can miss uncommon and delayed harms. Evidence from a related compound does not establish the safety of CJC-1295 NO DAC.

Source-reported adverse effects and cautions

  • Generally well tolerated; occasional mild side effects may include injection‑site reactions (redness, swelling), transient flushing, or headache[11].
  • Sources are available for independent reading. Individual claims and research schedules have not yet undergone an independent clinical review by Pep Science.

    Source-derived research information. Table phases retain the source’s actual duration; open-ended phases are not converted into a fixed eight-week course. Review the original study before interpreting a schedule.

    Standard / Gradual Approach (3 mL = ~1.67 mg/mL)

    Weeks 1–2Weeks 3–4Weeks 5–6Weeks 7–12
    WeekDaily Dose (mcg)Units (per injection) (mL)
    Weeks 1–2100 mcg6 units (0.06 mL)
    Weeks 3–4150 mcg9 units (0.09 mL)
    Weeks 5–6200 mcg12 units (0.12 mL)
    Weeks 7–12250–300 mcg15–18 units (0.15–0.18 mL)

    Frequency: Inject once daily subcutaneously, typically at bedtime to align with natural nocturnal GH pulsatility[2][3]. For ≤10‑unit (≤0.10 mL) administrations (Weeks 1–4), consider 30‑ or 50‑unit insulin syringes for improved readability.

    Additional schedule context & duration

    Concise summary of the once‑daily regimen.

    • Goal: Stimulate pulsatile GH release and elevate IGF‑1 levels to support body composition, recovery, and overall metabolic health[2][5].
    • Schedule: Daily subcutaneous injections for 8–12 weeks (extend to 16 weeks if desired).
    • Dose Range: 100–300 mcg daily with gradual titration.
    • Reconstitution: 3.0 mL per 5 mg vial (~1.67 mg/mL) for accurate unit measurements.
    • Storage: Lyophilized refrigerated or frozen; reconstituted refrigerated; avoid repeated freeze–thaw.

    Suggested daily titration approach.

    • Start: 100–150 mcg daily; increase by ~50 mcg every 1–2 weeks as tolerated.
    • Target: 200–300 mcg daily by Weeks 5–12.
    • Frequency: Once per day (subcutaneous), preferably at bedtime.
    • Cycle Length: 8–12 weeks; optional extension to 16 weeks.
    • Timing: Administer at bedtime to align with natural nocturnal GH pulses; rotate injection sites.

    Preparation

    Preparation and stability depend on the formulation, diluent, container and handling. The source-specific notes below apply to the selected record.
    Reconstitution Steps
    1. Draw 3.0 mL bacteriostatic water with a sterile syringe.
    2. Inject slowly down the vial wall; avoid foaming.
    3. Gently swirl/roll until dissolved (do not shake).
    4. Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.

    Storage Instructions

    Proper storage preserves peptide quality.

    • Lyophilized: Store at 2–8 °C (35.6–46.4 °F); for extended storage, freeze at ≤−20 °C (≤−4 °F); minimize moisture exposure.
    • Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within 1–2 weeks; avoid freeze–thaw cycles.
    • Allow vials to reach room temperature before opening to reduce condensation uptake.

    Injection Technique

    General subcutaneous guidance from clinical best‑practice resources[12].

    • Clean the vial stopper and skin with alcohol; allow to dry.
    • Pinch a skinfold; insert the needle at 45–90° into subcutaneous tissue[12][13].
    • Do not aspirate for subcutaneous injections; inject slowly and steadily[12].
    • Rotate sites systematically (abdomen, thighs, upper arms) to avoid lipohypertrophy[14].

    Materials & quantity planning

    Source materials checklist · 5 mg

    Plan based on an 8–12 week daily protocol with gradual titration.

    • Peptide Vials (CJC-1295 NO DAC, 5 mg each):

      • 8 weeks ≈ 2 vials
      • 12 weeks ≈ 3 vials
      • 16 weeks ≈ 4 vials
    • Insulin Syringes (U‑100):

      • Per week: 7 syringes (1/day)
      • 8 weeks: 56 syringes
      • 12 weeks: 84 syringes
      • 16 weeks: 112 syringes
    • Bacteriostatic Water (10 mL bottles): Use ~3.0 mL per vial for reconstitution.

      • 8 weeks (2 vials): 6 mL1 × 10 mL bottle
      • 12 weeks (3 vials): 9 mL1 × 10 mL bottle
      • 16 weeks (4 vials): 12 mL2 × 10 mL bottles
    • Alcohol Swabs: One for the vial stopper + one for the injection site each day.

      • Per week: 14 swabs (2/day)
      • 8 weeks: 112 swabs → recommend 2 × 100‑count boxes
      • 12 weeks: 168 swabs → recommend 2 × 100‑count boxes
      • 16 weeks: 224 swabs → recommend 3 × 100‑count boxes

    Calculate a phased quantity

    Enter each finite phase from the schedule you are studying. Open-ended phases need an explicit duration. Calculation uses 5 mg per vial and 3 mL per vial.

    Complete each phase to calculate totals.

    Quantity estimates exclude preparation losses and expiry. Follow the formulation’s handling and disposal requirements.
