AOD-9604 for fat loss - is it actually doing anything or am I wasting my time??

ok so ive been running AOD for about 6 weeks now at 300mcg ED subq fasted in the morning and honestly im not sure if i can attribute anything to it or if its just my diet being tighter

here's what i know (or think i know) - its basically just the c-terminal fragment of hGH, specifically the last 15 amino acids or whatever, and the whole selling point is it supposedly has the lipolytic effects of GH but WITHOUT the insulin resistance issues or the IGF-1 driven growth stuff. that part actually makes sense to me mechanistically

the studies i keep seeing referenced are mostly like early 2000s obese mouse studies lol and then there was that phase 2/3 clinical trial from Metabolic Pharmaceuticals that basically flopped and they couldnt replicate the results in humans at scale. that kinda kills my confidence tbh

BUT people swear by it on here and other forums. like SWEAR by it. and i dunno if thats placebo or synergy with other compounds they're running or what

im currently stacking it with ipamorelin/CJC no DAC so theres def other stuff going on and i cant isolate the variable

so my actual questions are:

1. has anyone run AOD completely SOLO with no other peptides or compounds and noticed legit body comp changes

2. does the dosing actually matter like is 300mcg underdosing, ive seen people go up to 500-600mcg

3. timing - some guys say post workout not fasted morning, does anyone have a rationale for that beyond broscience

4. is there ANY decent human data beyond those failed trials that im missing or is this genuinely one of those compounds where we're just running it on vibes and mouse studies

not trying to trash it, genuinely want to understand if theres a mechanism here that holds up or if im just injecting expensive water every morning lol

ok so I just want to say first that I'm pretty new to all this so take what I say with a giant grain of salt, but I actually had similar questions when I was researching AOD before starting my own healing protocol so I've gone down this rabbit hole a bit

yeah this is exactly what worried me when I was looking into it too. not sure if this is dumb but I actually got kind of reassured by the mechanism at least? like the lipolytic pathway stuff does seem to make biological sense even if the human trial results were underwhelming. but I dunno, I'm definitely not qualified to evaluate that stuff properly

to your question about running it solo - I can't personally answer that because I haven't run AOD specifically, but from what I've read the people who seem to report the most noticeable results are usually stacking it with something else like you are, which makes it basically impossible to know what's doing what. which is frustrating

the variable isolation problem you mentioned is a really good point and honestly I think that's why there's so much conflicting anecdote on here. like someone stacking it with a GHRH/GHRP combo and eating in a deficit is going to have a hard time saying what's actually moving the needle

I'm curious about your experience so far though - even without being sure if it's the AOD specifically, are you actually seeing body comp changes you can point to? like tape measurements or anything objective? because that would at least tell you SOMETHING is working even if you can't isolate which part of your stack it is

sorry if that's an obvious question, I just find tracking data really helpful when everything else feels uncertain

Hey, really appreciate the thoughtful discussion here, both of you are asking the right kinds of questions honestly.

So I want to gently push back on this a little bit, not because I think AOD is some miracle compound, but I think calling those Metabolic Pharmaceuticals trials a "flop" might be a bit of an oversimplification? My understanding is that the phase 2b results were actually somewhat promising for certain subgroups, and the issue was more about scale and the specific obese patient population they were targeting for a pharmaceutical approval pathway. That's a very different context than someone already doing the work on diet and exercise using it as a supporting tool. Pharmaceutical approval standards are brutal and the failure to get through trials doesn't always mean the compound doesn't do anything at all, it often just means it doesn't do enough to justify drug status by those specific criteria.

I'm not saying that makes the evidence strong, it genuinely isn't. But there's a difference between "didn't work as a standalone obesity drug at scale" and "has no lipolytic mechanism worth considering."

This is such a good question and I love that you're thinking about tracking because that matters so much regardless of which compound we're talking about.

To answer your dosing question IronGut, I've seen more experienced folks suggest that 300mcg is honestly on the lower end and that the 500mcg range seems to be where more people report feeling like something is happening. Though I'll be real, even that is mostly anecdote layered on top of anecdote.

The timing thing I actually lean toward the fasted morning approach having more rationale behind it given the whole low insulin environment piece, which theoretically should let the lipolytic mechanism do its thing more effectively. Post workout has its own logic but I find the fasted argument a little more coherent mechanistically.

Just my two cents, take it for what it's worth from someone who's not a researcher by any stretch!
