What is AOD-9604?
AOD-9604 (Anti-Obesity Drug 9604) is a modified, stabilised version of growth hormone fragment 176-191. It derives from the lipolytic C-terminal portion of HGH (amino acids 176-191) with the addition of a tyrosine at the N-terminus, which improves the stability of the molecule.
Like the “basic” HGH Frag 176-191, AOD-9604 isolates the lipolytic (fat-burning) action of growth hormone — without activating IGF-1, without an effect on growth and with minimal effect on glucose/insulin levels. It was developed specifically as a research molecule against obesity.
It is studied in research for lipolysis, reduction of body fat and lipid metabolism. Compared with full growth hormone or with IGF-1 analogues such as IGF-1 LR3, AOD-9604 focuses exclusively on the lipolytic arm. See the range in the all peptides category.
In the Peptology version, it is supplied as a lyophilised research-grade powder with purity > 99%, in a 5 mg form. It is intended exclusively for scientific, research and in vitro applications — it is not a medicine and is prohibited in sport (WADA).
Available form: 5 mg
5 MG
Typical research form
High-purity lyophilised powder with a laboratory certificate for each batch.
STRUCTURE
176-191 + Tyr
The lipolytic portion of HGH with tyrosine for stability.
How AOD-9604 works — targeted lipolysis
LIPOLYSIS
Stimulates the breakdown of stored lipids (lipolysis) in fat cells — the main studied effect.
LIPOGENESIS INHIBITION
It is also studied for inhibition of the formation of new fat (lipogenesis), enhancing the overall effect on body composition.
NO IGF-1 / GLUCOSE
It does not activate IGF-1 or significantly affect glucose/insulin — its key characteristic.
How it differs from the “plain” HGH Frag 176-191
AOD-9604 is essentially the stabilised version of HGH Frag 176-191: the addition of tyrosine improves its stability. They share the same rationale — isolating the lipolytic action of GH without an increase in IGF-1 or an effect on glucose — with AOD-9604 having been developed specifically as a research molecule against obesity.
This is how it differs substantially from full growth hormone (which carries the whole range of actions) and from IGF-1 analogues. The mechanisms come from preclinical studies.

Research
Lipolysis and body composition
AOD-9604 was developed as a research molecule against obesity: in preclinical studies it reproduces the lipolytic action of growth hormone, promoting fat breakdown and studied inhibition of lipogenesis.
Separation of GH actions
The central point of the research is that the molecule does not activate IGF-1 or significantly affect glucose — something that differentiates it from the use of full growth hormone and makes it “focused” on lipolysis.
Data limitations
Clinical data in humans are limited and the results are not always consistent. AOD-9604 remains a research molecule, not approved, and prohibited by WADA.
Note: Scientific reference based on preclinical data. It is not medical advice or a claim for the product.
In brief — scientific profile
- Stabilised GH fragment 176-191 — with tyrosine for improved stability
- Targeted lipolysis — fat breakdown + inhibition of lipogenesis (preclinical)
- No IGF-1 activation — “isolates” fat burning
- Minimal effect on glucose — unlike full GH
- Anti-obesity research molecule — stabilised version of HGH Frag
- Research product — prohibited in sport (WADA)
Side effects and safety
Because of its “focused” profile (no IGF-1 activation or the full actions of GH), AOD-9604 is generally considered well tolerated in the available data. The reactions reported are mostly mild.
Common
- Injection-site reactions/redness
- Transient headache
- Mild fatigue
Less common
- Dizziness
- Transient nausea
- Itching at the site
Precautions
- Allergic reaction / hypersensitivity
- Limited data in humans
- Prohibited in sport (WADA)
Despite the focused profile, any use must remain within the research context. Scientific reference, not an instruction for use.

How does it differ from HGH Frag 176-191?
It is its stabilised version. HGH Frag 176-191 is the basic fragment; AOD-9604 adds a tyrosine that improves stability. They share the same lipolytic rationale.
Does AOD-9604 raise IGF-1 like HGH?
No. In published studies in humans , IGF-1 does not increase after AOD-9604.

Research protocols
Important: Reference information for research purposes — not a recommendation for use or medical advice.
In the research literature, AOD-9604 schedules take the lipolytic character into account:
- It is often studied administered away from meals (low insulin) for optimal lipolysis
- Evening or pre-exercise timing is investigated in some protocols
- Body composition markers are used for monitoring
It is often studied alongside HGH Frag 176-191. The schedules come from the literature and do not constitute a recommendation for individual use.
Storage and reconstitution
Supplied as a lyophilised powder in a 5 mg vial. Lyophilised, it is stable at room temperature, away from light/moisture. For reconstitution, the recommended solvent is Peptide Matrix Water™, which significantly extends the life of the solution.
- Before reconstitution: room temperature, away from light/moisture; up to 24 months.
- With Peptide Matrix Water™ (recommended): refrigerator 2–8 °C up to 60 days — the best stability option.
- With bacteriostatic water or sterile water: refrigerator 2–8 °C up to 28 days. No re-freezing.
- Reconstitution: add the solvent slowly down the wall, without vigorous agitation.
Laboratory tip: Add Peptide Matrix Water™ to your basket — the recommended stabilising solvent for all reconstituted peptides.
Laboratory protocol — reconstitution, research protocols, storage
Standard protocol, applicable to all research peptides in the Peptology catalogue. For the concentration of the solution (mg/mL) per vial, use the peptide reconstitution calculator.
The 60-second protocol
1. SOLVENT
2. RECONSTITUTION
The solvent is added to the wall of the vial, without agitation, then wait 10–15 minutes.
3. CALCULATION
Calculator → concentration in mg/mL
4. STORAGE
+2 °C to +8 °C, up to 60 days with Peptide Matrix Water
Quick reference
| Parameter | Value |
|---|---|
| Form | Lyophilised powder |
| Solvent | Peptide Matrix Water |
| Volume for reconstitution | 1–3 mL — 3 mL maximum (capacity of the standard vial) |
| Storage before reconstitution | Room temperature, protected from direct light (refrigeration is not mandatory) |
| After reconstitution | Up to 60 days at +2 °C to +8 °C with Peptide Matrix Water |
What you will need
Precision pipette
Calibrated, 100–1000 µL — for accurate measurement of the volume of solvent added to the vial.
70% alcohol pads
Two pads — to disinfect the peptide vial and the solvent vial.
Stabilised solvent for lyophilised peptides. Why this one.
Five rules for reconstitution
| ✅ Correct | ❌ Wrong |
|---|---|
| Disinfect the stoppers and the work surface with 70% alcohol, work with gloves | Working without disinfection |
| The solvent is added slowly down the wall of the vial | Direct jet onto the powder — foaming and denaturation |
| Light swirling between the palms | Shaking — foam, on which the peptides denature |
| Wait 10–15 minutes at room temperature | Mechanical mixing or heating |
| Visual inspection: clear, without particles | Using a cloudy or coloured solution |
Calculating the concentration
⚠️ Maximum 3 mL of solvent. The standard vial does not allow a larger volume — do not exceed it during reconstitution.
- Concentration (mg/mL) = mg in the vial ÷ mL of solvent
- Volume per sample (mL) = amount per sample (mg) ÷ concentration (mg/mL)
- 1 mg/mL = 1 µg/µL · 1 mL = 1000 µL
Reconstitution per vial — solvent: Peptide Matrix Water. Concentration after addition (1 mg/mL = 1 µg/µL):
| Vial | + 1 mL | + 2 mL | + 3 mL |
|---|---|---|---|
| 5 mg | 5 mg/mL | 2.5 mg/mL | 1.67 mg/mL |
👉 For any vial and solvent volume — use the calculator. It calculates the concentration (mg/mL, µg/µL) and the volume per sample (mL, µL).
Storage
BEFORE RECONSTITUTION
Room temperature, protected from direct light, in the original packaging. Refrigeration is not mandatory.
AFTER RECONSTITUTION
+2 °C to +8 °C, up to 60 days with Peptide Matrix Water. Discard the remainder after this period.
FREEZING
Not recommended. Freeze/thaw cycles degrade the structure of the peptide.
Four mistakes to avoid
1. Shaking for “faster dissolution”
Foam = denaturation. Only gentle swirling between the palms.
2. Unsuitable solvent
For the stability of the peptide structure, use only a sterile, purpose-designed solvent — Peptide Matrix Water is recommended.
3. Ignoring slight cloudiness
If it is not completely clear = the sample does not meet the criteria for work.
4. Removing it from the refrigerator “for an hour or two”
Short exposures add up and jeopardise stability.
