An interesting FYI is a comment made by Peter Attia on his podcast.

He had a patient with metabolic markers that were not improving and they had exhausted all the typical avenues. Presumably they were things like weight loss.

They put the patient on GLP-1 but injected into the thighs (or butt, I don't recall) for the metabolic benefits without the hunger blunting effects.

It seems like GLP1, even in skinny patients (implied by Attia in this particular case), has metabolic benefits.

The longevity community seems to be hinting that there may be geroprotective aspects of GLp1 as well, so we may be looking at the benefits beyond weight loss for metabolism.

It shouldn't make any difference where you pin it, it's systemic it just has to be administered subcutaneously because it's a peptide and it isn't orally active.

Don't listen to these YouTubers about health and fitness, most of them are clueless

It shouldn't, and yet for me it seems to make a difference! I don't think it's placebo, because I am really losing weight. My anecdata: When I start with a particular dose of GLP-1, I inject in thigh. I get strong appetite suppression, heart rate increase, digestion slow down etc. After some time, the effect decreases as my body adjusts. I then move injection to abdomen, and I get a huge bump in suppression, systemic effects, etc. No idea why this happens, but I've seen it with Zepbound and 5, 7.5, and 10mg. It's allowed me to stay on each dose for far longer than my doctor expected.

There were no recommendations.

Usually this type of anecdata becomes the basis of legitimate, controlled studies and over time can inform and/or adjust.

It would be premature to simply write off all influencers or limiting to only accept the medical profession as the immutable truth.

The reality tends to exist somewhere in the middle, outside of a formal proof.

I've listened to many health influencers and among the legitimate and balanced tend to be Rhonda Patrick and Peter Attia.

Attia provides guidelines for how to think about items, but usually it's the fan base that tends to sully the messaging as the base tends to be far more polarized and dogmatic over bits.

It is interesting to see that there is another poster confirming a slightly different effect though. Regardless of things being "systemic", just understanding that fluids dynamics are complex, I imagine diffusion of a systemic molecule like GLp1 could possibly be variable? Or perhaps there is a localized tissue fatigue?

Many potential options do exist to propose as hypothesis.

Peter Attia is a graduate of Stanford medical school and spent 5 years in surgical residency at Johns Hopkins, and his podcast is largely using his expertise to give context to recently published research. His opinions are always pretty directly linked to peer reviewed research and he updates his stances as new research becomes available and explains why (eg, his shift away from fasting).

He really shouldn't be lumped in with the general "health and fitness Youtubers".

While the area under the curve for glp1 administration may be the same, good chance that the story is informing us of a mechanism such as the absorption rate between two different sites.

Slower absorption in the thigh may blunt the immediate peak dosing and the acute hunger effects.

As always, the small details matter. I'd guess that pharmacology also has their own thundering herd problem with the dosing of certain drugs.

One of the interesting bits about pharmacology seems to not be the active molecule as much as the innovations in delivery mechanism.

Pseudoscience scares me. There are so many people that believe this nonsense and basic understanding of medicine disproves many of those claims.

(Outer) Thigh, upper arms and stomach are the on-label injection sites for these drugs.

Thanks for the dumbest thing I've read all day
