How this works
Mechanism of action and pharmacokinetic profile from published data.
AOD-9604 is a synthetic 16-amino-acid fragment of human growth hormone (hGH), corresponding to residues 176β191 of the hGH sequence. In preclinical studies, it demonstrated fat-mobilising (lipolytic) effects without the growth-promoting and insulin-resistance effects of the full hGH molecule. In Australia, AOD-9604 was briefly listed as a food ingredient before the TGA reviewed its classification and removed it from the food ingredients register. Human clinical trial evidence is limited: early Phase 2 trials in obesity showed modest body-weight effects, and the development programme was discontinued before Phase 3 completion.
- Time to peak (Tmax)
- Not characterised from published human PK studies.
- Clearance
- Proteolytic degradation expected; no regulatory-standard PK profile exists.
- Elimination half-life
- Not formally established. Phase 1/2 trial data suggest a short plasma half-life consistent with a small peptide.
- Bioavailability
- Phase 2 trials used oral and subcutaneous routes. Oral bioavailability of intact peptide is expected to be low; trial data are not publicly reported in sufficient detail.

Your journey
Where you are in a typical protocol, and what one dose cycle looks like. Educational β your prescriber tailors the plan to you.
Protocol timeline
Investigational phase (no approved schedule)
Weeks 1+What to expect: AOD-9604 has no approved therapeutic dosing schedule for human use, Published Phase 2 trials explored oral and subcutaneous routes at varying doses; no standard regimen was established, The development programme was discontinued before Phase 3; no peer-reviewed maintenance schedule exists, Any use outside an approved clinical trial is unregulated and lacks a formal efficacy or safety profile
Focus on: Understand that AOD-9604 is not approved by the TGA, FDA, MHRA, or EMA for any therapeutic purpose, Any use should occur only within the context of an approved clinical trial or under direct medical supervision, Report any unexpected symptoms promptly to your prescriber or trial team, Do not source this compound from unregulated or compounding suppliers without explicit medical oversight
Common adjustments: Dose, frequency, and route varied across published studies β no titration ladder has been validated, A clinical trial investigator or prescriber operating within a registered study would determine any protocol adjustments

Observed outcomes, adverse effects, and lifecycle considerations from published trial data.
Benefits
No approved human dosing protocol exists
AOD-9604 development as a weight-management drug was discontinued before completing Phase 3. There is no approved dose, schedule, or monitoring protocol. Human trial data from Phase 2 obesity studies showed modest effects that were not compelling enough to advance.
Getting started and finding your footing
This is your very first week, and the most important thing right now is simply showing up and building the habit of your injection routine. Your body is being introduced to something new, so don't be surprised if you notice mild redness or tenderness at the injection site β this is very common. There are unlikely to be any visible physical changes yet, and that's completely normal; this week is all about starting well.
Settling into your injection routine
By now your injection technique is likely feeling a little more familiar, even if it still feels a bit daunting. Some people notice mild fatigue or a subtle change in appetite around this time, while others feel no different at all β both are normal. Keep your expectations grounded; meaningful changes in body composition take time, and consistency now is what lays the foundation.
Staying consistent through the early stage
Week three can be one of the trickier weeks β you're past the novelty of starting but results aren't visible yet, which can feel discouraging. Some people report mild gastrointestinal discomfort, such as nausea or bloating, particularly around their injection window. Stick with it, keep your hydration and nutrition dialled in, and remember that what's happening right now may not be visible but it matters.
Completing your first month β a real milestone
Finishing your first four weeks is genuinely worth acknowledging β building any new health habit is hard, and you've done it. Nausea or mild digestive sensitivity may still come and go, especially on injection days, and that's still within the normal range of experiences at this stage. You might not see dramatic changes in the mirror yet, but your consistency is doing real work.
Dose adjustment may begin β stay the course
If your prescriber has recommended a dose adjustment this week, you may notice side effects like nausea or fatigue becoming slightly more noticeable again as your body adapts β this often settles within a few days. Some people begin to notice a subtle shift in appetite or food cravings around this time. Follow your prescriber's instructions carefully and report any concerns rather than adjusting things on your own.
Appetite changes becoming more noticeable
Many people start to notice they feel satisfied with smaller portions or find that certain foods are less appealing than they used to be. This is a good opportunity to be intentional about what you're eating β leaning into protein-rich, nutritious foods will help your body make the most of these changes. If nausea is still a factor, small, frequent meals are often much easier to manage than large ones.
Building momentum with new eating patterns
By week seven, many people find their new eating rhythm is beginning to feel more natural and less forced. It's worth checking in with yourself about energy levels, sleep quality, and how your clothes are fitting β these non-scale markers can be really encouraging when the number on the scales feels slow to move. Keep up your movement routine and be kind to yourself on harder days.
Lifecycle factors
The development programme was discontinued
AOD-9604 completed Phase 2 obesity trials but was not taken to Phase 3 by its developer. This is not the same as being proven safe and effective β it means the evidence threshold for a serious weight-management medicine was not met.
TGA food-ingredient classification was revoked
AOD-9604 was briefly listed in Australia as a food ingredient. The TGA reviewed its classification and removed it from the food ingredients register because it did not meet the criteria. It is not a food ingredient and it is not a licensed medicine.
Store your compound correctly and check it before use
Follow your prescriber's instructions for storage β most compounded peptides need to be kept refrigerated and away from light. Before each use, visually inspect the solution: it should be clear and free of particles or discolouration. If anything looks off, don't use it β contact your prescriber or the compounding pharmacy. Never use a preparation past its expiry date or if it has been stored incorrectly.
Keep a simple symptom log to share with your prescriber
Take 60 seconds after each injection to jot down a quick note β what time you injected, how you felt in the hours after, any nausea, fatigue, or injection-site reactions. Even a note in your phone's notes app works perfectly. This kind of simple log makes your check-in conversations with your prescriber far more useful and means nothing gets forgotten between appointments.

Adherence tips
Rotate your injection sites consistently
Inject into the subcutaneous tissue of your abdomen, thigh, or upper arm as directed by your prescriber, and rotate between spots each time to reduce the chance of localised irritation or lumps under the skin. A simple way to do this is to mentally divide your abdomen into a grid and work your way around it. Keep each new injection site at least 1β2 cm away from the last. Follow your prescriber's instructions on technique and site selection.
Let your injection warm to room temperature first
If your compound is stored in the fridge, take it out 10β15 minutes before injecting to allow it to reach room temperature. Injecting a cold solution can increase discomfort and stinging at the site. Never use a microwave or hot water to speed this up β simply leave it on the bench while you prepare everything else.
Inject at the same time each day to build your habit
Choosing a consistent time for your injection β many people prefer first thing in the morning before breakfast β makes it much easier to remember and helps your body adapt to a predictable rhythm. Set a phone reminder with a label like 'morning routine' until it becomes automatic. Follow your prescriber's instructions about the optimal timing for your individual situation.
Keep injection days lighter on the plate
Many people find that eating lighter, low-fat meals in the few hours before and after their injection noticeably reduces nausea. Think a small bowl of oats with fruit for breakfast, or a piece of wholegrain toast with a boiled egg, rather than a big cooked meal. You can eat more normally once you're confident how your body responds.
Disclose to your doctor
Any unregulated compound should be declared to your prescriber β particularly relevant if you are using other medicines, planning surgery, or being investigated for a health condition.
Start every morning with a full glass of water
Before your morning coffee, before breakfast, before anything β drink a 250β300 mL glass of water as the very first thing you do each day. This simple habit kickstarts your hydration and has been shown to support appetite regulation. Keep a large (750 mLβ1 L) bottle on your desk or bench as a visual reminder to keep drinking throughout the day.
Sip ginger or peppermint tea when nausea hits
Rather than reaching for food when you feel queasy, try sipping a warm cup of ginger or peppermint herbal tea β both are widely available at Australian supermarkets and have a well-established reputation for settling an unsettled stomach. Drink it slowly over 15β20 minutes. Keeping tea bags in your bag or at your desk means you're never caught without a go-to nausea remedy.
Aim for 25β35g of protein at every main meal
When your appetite is reduced, it's easy to undereat protein without realising it β and protein is especially important for preserving muscle while your body composition is changing. Practically, 25β35g of protein looks like a 120β150g chicken breast, two eggs plus a tin of tuna, or a cup of Greek yoghurt with cottage cheese. Use the palm of your hand as a rough guide: one palm-sized serve of a protein-rich food per meal is a solid starting point.
Eat small meals every 3β4 hours rather than skipping
When appetite is suppressed, skipping meals might feel natural β but going too long without eating can worsen nausea, drop your energy, and make it harder to meet your nutritional needs. Set a gentle alarm to eat something small every 3β4 hours, even if it's just a small tub of yoghurt, a handful of nuts, or a piece of fruit. Keeping easy, nourishing snacks visible and accessible at home makes this much easier to stick to.
Start with 20β30 minute walks and build from there
You don't need to overhaul your exercise routine all at once β even a 20β30 minute walk most days is a meaningful contribution to your goals and is well-tolerated by most people in the early weeks. Aim to gradually build toward 150 minutes of moderate movement per week, as per Australian physical activity guidelines. If you feel fatigued on injection days, it's fine to make those your lighter days and move more on others.
Include two resistance training sessions per week
Resistance or strength training β whether that's weights, bodyweight exercises, or resistance bands β is one of the most effective ways to support lean muscle while working toward body composition changes. Two sessions per week of 30β45 minutes is a realistic and achievable target for most people. If you're new to strength training, a session with a qualified exercise physiologist or personal trainer can help you start safely and confidently.
Protect 7β9 hours of sleep as part of your programme
Sleep quality has a significant and direct impact on hunger hormones, energy levels, and the body's ability to manage fat metabolism β so it's not optional. Aim for 7β9 hours per night and try to keep your wake and sleep times consistent, even on weekends. If you're finding sleep difficult, reducing screen exposure in the hour before bed and keeping your bedroom cool (around 18β20Β°C) are two changes that make a measurable difference for many people.
Track non-scale wins alongside your weight
The number on the scale is just one data point, and it doesn't always reflect what's actually happening in your body β especially in the early weeks. Keep a simple weekly note of other markers: how your clothes fit, your energy at 3pm, how far you walked, your sleep quality, or how you handled a stressful day around food. These 'non-scale victories' are often more motivating and more meaningful than a number, and they help you see the bigger picture when weight loss is slower than you'd like.
Be honest about hard weeks β they don't erase progress
There will be weeks where you feel lousy, where nausea gets the better of you, or where you eat in a way that doesn't align with your goals. This is part of the process for almost everyone, and a difficult week doesn't undo what came before it. What matters most is how quickly you return to your routine β not whether you had a perfect run. Try keeping a brief one-line journal entry each day: even 'today was hard but I'm still here' counts as progress.

Avoid: Fatty, fried, or strongly spiced foods, Large meals in a single sitting
Moderate nausea
Nutrition: Prioritise bland, easily digestible foods, If eating is difficult, try liquid nutrition such as diluted fruit juice, clear soups, or electrolyte drinks
Hydration: Aim to maintain at least 1.5β2 L of fluid per day, Oral rehydration solutions may help if fluid intake is reduced
Avoid: Alcohol, Dairy-heavy meals, Strong food odours where possible
β Contact your prescriber or trial team if nausea persists beyond 24β48 hours or prevents adequate fluid intake.
Severe nausea
Nutrition: Focus on maintaining any oral intake possible; even small sips are beneficial
Hydration: Seek medical guidance promptly β intravenous fluid support may be needed if oral intake is not possible
Avoid: Solid foods until vomiting has subsided
β Seek urgent medical attention if you are unable to keep fluids down for more than 12 hours, feel faint, or show signs of dehydration (dark urine, dry mouth, dizziness).
Food guidance by situation
Prefer: Plain crackers, dry toast, or plain rice, Ginger tea or ginger biscuits, Cold or room-temperature fluids, Clear broths or soups
Limit: Dairy-heavy foods, High-fat snacks
Avoid: Fatty or fried foods, Strongly spiced dishes, Alcohol
Bland, low-fat foods are generally better tolerated when nausea is present and place less demand on gastric motility.
Prefer: Nutrient-dense small portions β e.g. nut butter on toast, yoghurt, eggs, Fortified drinks or smoothies if solid food is unappealing, Foods with familiar, mild flavours
Limit: Skipping meals entirely β even small amounts of food help maintain energy and muscle mass
Avoid: Replacing meals with nutrient-poor options such as confectionery or soft drinks
Maintaining adequate caloric and protein intake is important; small frequent meals can help when appetite is reduced.
