Quickstart Highlights

AOD-9604 dosage protocols leverage this synthetic 16‑amino‑acid fragment (Tyr‑hGH 177–191) to support lipolysis (fat breakdown) and inhibit lipogenesis (fat storage) without elevating IGF‑1 levels or causing insulin resistance^[1][2]. Clinical trials have demonstrated that AOD‑9604 exhibits a placebo‑like safety profile in obese adults, making it a well‑tolerated option for metabolic support^[3]. This educational protocol outlines a once‑daily subcutaneous approach using a practical dilution for clear insulin‑syringe measurements.

• Reconstitute: Add 3.0 mL bacteriostatic water → ~1.667 mg/mL (1667 mcg/mL) concentration.
• Typical daily range: 300–500 mcg once daily (gradual titration).
• Easy measuring: At 1.667 mg/mL, 1 unit = 0.01 mL ≈ 16.67 mcg on a U‑100 insulin syringe.
• Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.

Protocol Overview

Concise summary of the once‑daily regimen.

• Goal: Support reduction of fat mass and enhance fat oxidation over time^[1][4].
• Schedule: Daily subcutaneous injections for 8–12 weeks (extend to 16 weeks if desired).
• Dose Range: 300–500 mcg daily with gradual titration.
• Reconstitution: 3.0 mL per 5 mg vial (~1.667 mg/mL) for accurate unit measurements.
• Storage: Lyophilized frozen; reconstituted refrigerated; avoid repeated freeze–thaw.

Dosing Protocol

Suggested daily titration approach.

• Start: 300 mcg daily for Weeks 1–4; increase to 500 mcg for Weeks 5–12 as tolerated.
• Target: 500 mcg daily by Week 5 and maintain through cycle completion.
• Frequency: Once per day (subcutaneous).
• Cycle Length: 8–12 weeks; optional extension to 16 weeks.
• Timing: Morning administration (fasted) is common; rotate injection sites.

Storage Instructions

Proper storage preserves peptide quality.

• Lyophilized: Store at −20 °C (−4 °F) in dry, dark conditions; stable for 1+ year^[5].
• Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within 3–4 weeks and avoid freeze–thaw^[6].
• 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 (U‑100, 29–31 gauge); dispose in a sharps container^[7].
• Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation and prevent lipohypertrophy^[8].
• Inject slowly; wait a few seconds before withdrawing the needle.
• Each 2 mg vial provides approximately 4 days of dosing at 500 mcg/day or 6–7 days at 300 mcg/day.

How This Works

AOD‑9604 is a modified C‑terminal fragment of human growth hormone that retains the lipolytic (fat‑reducing) domain without the growth‑promoting effects^[1]. It binds to adipose tissue and triggers breakdown of stored fat while blocking new fat storage (re‑esterification) in adipocytes^[4]. At the molecular level, chronic AOD‑9604 administration upregulates β₃‑adrenergic receptors in fat tissue, reversing obesity‑related suppression of these fat‑burning receptors^[9]. Unlike full‑length hGH, AOD‑9604 does not meaningfully elevate IGF‑1 levels or worsen glucose tolerance, making its tolerability indistinguishable from placebo in human trials^[2][3].

Potential Benefits & Side Effects

Observations from preclinical and clinical literature.

• Supports reductions in fat mass and increases in fat oxidation over time; clinical trials showed modest but statistically significant weight loss (approximately 2.6 kg vs. 0.8 kg placebo over 12 weeks at 1 mg/day)^[10].
• Preferential loss of abdominal fat observed, resembling the pattern seen with low‑dose hGH therapy^[10].
• Does not meaningfully raise IGF‑1 and shows a placebo‑like safety profile in human studies; no anti‑AOD9604 antibodies detected^[2][3].
• Emerging regenerative potential: preclinical studies suggest possible cartilage repair and bone health benefits^[11][12].
• Generally well tolerated; occasional mild injection‑site reactions (redness/itch) may occur with subcutaneous administration.

Lifestyle Factors

Complementary strategies for best outcomes.

• Pair with a hypocaloric, protein‑forward diet tailored to energy needs; AOD‑9604 is best viewed as a supportive aid to fat loss rather than a stand‑alone solution^[10].
• Combine resistance training and aerobic activity to reinforce metabolic adaptations.
• Prioritize sleep and stress management to support adherence and recovery.

Injection Technique

General subcutaneous guidance from clinical best‑practice resources^[7].

• Clean the vial stopper and skin with alcohol; allow to dry completely^[8].
• Pinch a skinfold; insert the needle at 90° (or 45° if very little subcutaneous fat) into subcutaneous tissue^[7].
• Do not aspirate for subcutaneous injections; inject slowly and steadily^[13].
• Rotate sites systematically (abdomen at least 2 inches from navel, thighs, upper arms) to avoid lipohypertrophy^[8].
