CJC-1295 + GHRP-2 (10 mg Blend) Dosage Protocol

CJC-1295 + GHRP-2 Dosage Chart

The CJC-1295 + GHRP-2 peptide blend is dosed at 150 mcg–300 mcg daily via subcutaneous injection in educational protocols. A 10 mg blend reconstituted with bacteriostatic water yields about 3.33 mg/mL. This information is for research and educational use only.

  • Reconstitute: Add 3.0 mL bacteriostatic water → ~3.33 mg/mL concentration (1 unit ≈ 33.3 mcg).
  • Typical daily range: 100–300 mcg once daily (gradual titration).
  • Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL ≈ 33.3 mcg on a U-100 insulin syringe.
  • Storage: Lyophilized: refrigerate at 2–8 °C (35.6–46.4 °F) or freeze at −20 °C (−4 °F) for long-term; after reconstitution, refrigerate and use within 2–4 weeks.
CJC-1295 and GHRP-2 blend vial - CJC-1295 GHRP-2 dosage protocol

CJC-1295 is a long-acting GHRH analog that can elevate GH levels 2–10× baseline for approximately 6 days and increase IGF-1 by 1.5–3× for 9–11 days[1]. GHRP-2 is a ghrelin-mimetic secretagogue with a plasma half-life of ~30 minutes that triggers rapid GH pulses peaking within ~25 minutes of administration[3]. Combining these peptides leverages GHRP-2’s acute pulsatile release with CJC-1295’s sustained action. This educational protocol presents a once-daily subcutaneous approach using a practical dilution for clear insulin-syringe measurements.

Dosing & Reconstitution Guide

Educational guide for reconstitution and daily dosing

Standard / Gradual Approach (3 mL = ~3.33 mg/mL)

Week Daily Dose (mcg) Units (per injection) (mL)
Weeks 1–2 150 mcg (0.15 mg) 4.5 units (0.045 mL)
Weeks 3–12 300 mcg (0.30 mg) 9 units (0.09 mL)

Frequency: Tie timing to the research design. Human work supports acute synergistic GH release when GHRH and a growth hormone-releasing peptide are combined[6]. The cited study used controlled intravenous administration and does not define a bedtime subcutaneous schedule for this exact blend.

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.

Advanced / Twice-Daily Approach (3 mL = ~3.33 mg/mL)

Some protocols split the daily dose into two administrations (morning upon waking, fasted; and evening before bed) to enhance GH pulsatility[1]. Ensure doses are at least 3–8 hours apart to avoid overlapping GH pulses.

Week Dose per Injection (mcg) Units (per injection) (mL) Total Daily (mcg)
Weeks 1–2 100 mcg (0.10 mg) 3 units (0.03 mL) 200 mcg
Weeks 3–12 150 mcg (0.15 mg) 4.5 units (0.045 mL) 300 mcg

For ≤10-unit (≤0.10 mL) administrations, consider 30- or 50-unit insulin syringes for improved readability.

Supplies Needed

Plan based on an 8–16 week daily protocol with gradual titration (once-daily schedule).

  • Peptide Vials (CJC-1295 + GHRP-2, 10 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 mL → 1 × 10 mL bottle
    • 12 weeks (3 vials): 9 mL → 1 × 10 mL bottle
    • 16 weeks (4 vials): 12 mL → 2 × 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

Protocol Overview

Concise summary of the once-daily regimen.

  • Goal: Support enhanced GH pulsatility and sustained IGF-1 elevation over a defined research period[1].
  • Schedule: Daily subcutaneous injections for 8–12 weeks (extend to 16 weeks if desired).
  • Dose Range: 100–300 mcg daily (total blend) with gradual titration.
  • Reconstitution: 3.0 mL per 10 mg vial (~3.33 mg/mL) for accurate unit measurements.
  • Storage: Lyophilized refrigerated or frozen; reconstituted refrigerated; avoid repeated freeze–thaw.

Dosing Protocol

Suggested daily titration approach.

  • Start: 100–150 mcg daily for Weeks 1–2 to allow acclimatization[2].
  • Target: 250–300 mcg daily by Weeks 3–12.
  • Frequency: Once per day (subcutaneous), preferably evening/bedtime.
  • Cycle Length: 8–12 weeks; optional extension to 16 weeks.
  • Timing: Inject on an empty stomach; rotate injection sites.

Storage Instructions

Proper storage preserves peptide quality[9][10].

  • Lyophilized: Refrigerate at 2–8 °C (35.6–46.4 °F); freeze at −20 °C (−4 °F) for long-term storage exceeding several months.
  • Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within 2–4 weeks for optimal potency.
  • Allow vials to reach room temperature before opening to reduce condensation uptake.
  • If longer storage of reconstituted solution is needed, aliquot into sterile containers and freeze once; avoid repeated freeze–thaw.

Important Notes

Practical considerations for consistency and safety.

  • Use new sterile insulin syringes for each injection; dispose in a sharps container[7].
  • Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation.
  • Inject slowly on an empty stomach; GHRP-2’s GH response may be blunted by elevated blood glucose[4].
  • Document daily dose and site rotation to maintain consistency.
  • No post-cycle therapy is required; GH and IGF-1 levels return to baseline after cessation[1].

How This Works

CJC-1295 is a tetrasubstituted GHRH(1–29) analog engineered for extended half-life (~6–8 days) via protection from enzymatic degradation and reversible albumin binding[1]. A single dose can sustain elevated GH for approximately 6 days and IGF-1 elevation for 9–11 days. GHRP-2 is a synthetic hexapeptide ghrelin-mimetic that binds the GH secretagogue receptor (GHS-R1a), triggering acute GH pulses that peak within ~25 minutes[3]. Human research shows that GHRH and growth hormone-releasing peptide pathways can stimulate GH release synergistically[6]. This supports the pathway rationale, while the exact compounds and route in the cited study differ from this blend.

Potential Benefits & Side Effects

Observations from preclinical and clinical literature.

  • Sustained elevation of GH and IGF-1 levels over extended periods with once-daily or even less frequent dosing[1].
  • Long-term pediatric studies (8 months) reported no significant adverse effects or toxicities from GHRP-2 therapy[2].
  • GHRP-2 may transiently increase appetite due to ghrelin-like activity[4].
  • Mild, transient elevations in ACTH, cortisol, and prolactin may occur shortly after injection but remain within physiological ranges[5].
  • CJC-1295 at higher doses may cause transient vasodilatory effects such as facial flushing or brief lightheadedness[1].
  • Occasional mild injection-site reactions (redness, itching) may occur with subcutaneous administration.

Lifestyle Factors

Complementary strategies for best outcomes.

  • Pair with a balanced, protein-forward diet tailored to energy and recovery needs.
  • Combine resistance training and aerobic activity to complement GH-mediated anabolic and metabolic effects.
  • Prioritize quality sleep; nocturnal GH secretion is enhanced by adequate rest.
  • Inject on an empty stomach or after fasting for 2–3 hours; carbohydrate-rich meals may attenuate GHRP-2’s GH response[4].

Injection Technique

General subcutaneous guidance from clinical best-practice resources[7][8].

  • Clean the vial stopper and skin with alcohol; allow to dry.
  • Pinch a skinfold; insert the needle at 45–90° into subcutaneous tissue[7].
  • Do not aspirate for subcutaneous injections; inject slowly and steadily[8].
  • Rotate sites systematically (abdomen, thighs, upper arms) to avoid local tissue changes[11].
  • Withdraw the needle at the same angle; dispose immediately in a sharps container.
