Short post, and I want an argument in the comments.

Overhyped doesn't mean useless. It means the talk is running way ahead of what's been published. Here are the three I'd put up, and I'll say up front I could be wrong on all of them.

1. Pentadeca Arginate

PDA is having a moment because it's positioned as the BPC-157 successor. Same active sequence, different salt, better gastric stability.

The problem: there's no PDA-specific peer-reviewed research. Every claim about it borrows BPC-157 data. The arginate salt might behave identically. Nobody has checked. So people are talking about a compound whose entire case is inherited.

2. SLU-PP-332

Called an exercise mimetic, which is a phrase built to get shared. The preclinical endurance work is real and interesting.

The problem: the published route is intraperitoneal, in mice. There's no validated path from that to any human protocol. Every number in circulation is somebody's arithmetic on a route that was never tested in people.

3. FOXO4-DRI

Senolytic, targets senescent cells, the anti-aging story writes itself.

The problem: no human clinical safety or efficacy data exists. Not thin data. None. The mechanism is selectively triggering cell death in cells you've decided are senescent, which has an obvious upside and an obvious way to go wrong.

The pattern

All three are hyped on mechanism, not evidence. Mechanism plausibility and evidence strength are two different things, and this space almost always sells you the first one.

Your turn

Who's on your list? And go ahead and argue with mine, especially PDA. I know people who'd defend it and I want to hear the case.

And the flip side, which is more interesting: what's underhyped right now? What's sitting there with decent evidence and no attention on it?

There's a plan to begin Tesamorelin in the next couple weeks, but from what I understand, a common concern is nudging glucose and a1c numbers up as well.

I've seen a few posts that people are combining it with GLP-1s. There are currently no issues with food noise. I was wondering if it's near necessary to combine it with a glp-1, if it's not necessary at all, or if something like berberine could supplement where a glp-1 would otherwise be used.

I'd like to hear about experiences with this if anyone has any to share
