AOD-9604 is a modified fragment of human growth hormone (hGH), specifically amino acids 176โ191, engineered to focus on fat metabolism without triggering the broader growth effects associated with full-length hGH. This peptide has become a popular tool in obesity and lipolysis research due to its ability to stimulate the breakdown of adipose tissue while preserving lean mass. Unlike hGH, AOD-9604 does not affect insulin sensitivity or IGF-1 levels, making it a unique candidate for selective fat-loss pathways.

AOD-9604 is a modified peptide fragment derived from human growth hormone (hGH), specifically the C-terminus (176โ191 sequence). It is researched for its potential to stimulate fat metabolism without the growth-promoting effects associated with full-length hGH.
AOD-9604 works by stimulating lipolysis (the breakdown of fat) and inhibiting lipogenesis (the formation of fat), primarily through interaction with beta-adrenergic receptors and hormone-sensitive lipase. It does not bind to GH receptors, making it selective for fat metabolism in research models.
Our AOD-9604 is supplied as a lyophilized powder in sterile, single-use vials. It is synthesized in the USA under strict GMP-like lab conditions and tested to ensure the highest standards of purity and stability.
Store the lyophilized vial at -20ยฐC, in a dry and light-protected environment. Once reconstituted, refrigerate between 2โ8ยฐC and use within your research teamโs stability timeline.
Shop Peptides Direct guarantees โฅ98% purity, validated using HPLC and Mass Spectrometry. Every order includes a batch-specific Certificate of Analysis (COA) for full transparency.

AOD-9604 (2 mg & 5 mg Vials) Dosage Protocol
Quickstart Highlights
AOD-9604 dosage protocols leverage this synthetic 16โaminoโacid fragment (TyrโhGH 177โ191) to support lipolysis (fat breakdown) and inhibit lipogenesis (fat storage) without elevating IGFโ1 levels or causing insulin resistance[1][2]. Clinical trials have demonstrated that AODโ9604 exhibits a placeboโlike safety profile in obese adults, making it a wellโtolerated option for metabolic support[3]. This educational protocol outlines a onceโdaily subcutaneous approach using a practical dilution for clear insulinโsyringe measurements.
- 5 mg Vial Reconstitution: Add 3.0 mL bacteriostatic water โ ~1.667 mg/mL (1667 mcg/mL) concentration.
- 2 mg Vial Reconstitution: Add 3.0 mL bacteriostatic water โ ~0.667 mg/mL (667 mcg/mL) concentration.
- Typical daily range: 300โ500 mcg once daily (gradual titration).
- Easy measuring: At 1.667 mg/mL, 1 unit = 0.01 mL โ 16.7 mcg; at 0.667 mg/mL, 1 unit = 0.01 mL โ 6.7 mcg.
- Storage: Lyophilized: freeze at โ20 ยฐC (โ4 ยฐF); after reconstitution, refrigerate at 2โ8 ยฐC (35.6โ46.4 ยฐF); avoid freezeโthaw cycles.
Dosing & Reconstitution Guide
Educational guide for reconstitution and daily dosing
Standard / Gradual Approach (Both Vials)
| Week | Daily Dose (mcg) | 5 mg Vial (Units) | 2 mg Vial (Units) |
|---|---|---|---|
| Weeks 1โ4 | 300 mcg | 18 units (0.18 mL) | 45 units (0.45 mL) |
| Weeks 5โ12 | 500 mcg | 30 units (0.30 mL) | 75 units (0.75 mL) |
Frequency: Inject once daily subcutaneously (typically in the morning on an empty stomach). This schedule uses the largest practical dilution (3.0 mL) to keep perโinjection units manageable for better accuracy. Rotate injection sites (abdomen, thighs, upper arms) to minimize local irritation.
Reconstitution Steps (Both Vials)
- 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 2โ8 ยฐC (35.6โ46.4 ยฐF), protected from light.

- For โค10-unit (โค0.10 mL) administrations, consider 30- or 50-unit insulin syringes for improved readability.
How This Works
AODโ9604 is a modified Cโterminal fragment of human growth hormone that retains the lipolytic (fatโreducing) domain without the growthโpromoting effects[1]. It binds to adipose tissue and triggers breakdown of stored fat while blocking new fat storage (reโesterification) in adipocytes[4]. At the molecular level, chronic AODโ9604 administration upregulates ฮฒ3โadrenergic receptors in fat tissue, reversing obesityโrelated suppression of these fatโburning receptors[9]. Unlike fullโlength hGH, AODโ9604 does not meaningfully elevate IGFโ1 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 lowโdose hGH therapy[10].
- Does not meaningfully raise IGFโ1 and shows a placeboโlike safety profile in human studies; no antiโAOD9604 antibodies detected[2][3].
- Emerging regenerative potential: preclinical studies suggest possible cartilage repair and bone health benefits[11][12].
- Generally well tolerated; occasional mild injectionโsite reactions (redness/itch) may occur with subcutaneous administration.
Lifestyle Factors
Complementary strategies for best outcomes.
- Pair with a hypocaloric, proteinโforward diet tailored to energy needs; AODโ9604 is best viewed as a supportive aid to fat loss rather than a standโalone 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 bestโpractice resources[7].
- Clean the vial stopper and skin with alcohol; allow to dry completely[8].
- Pinch a skinfold; insert the needle at 90ยฐ (or 45ยฐ 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].
- Using a 30- or 50-unit insulin syringe improves accuracy when measuring small volumes.
