what do you guys actually use to store vials?
boring logistics question but it comes up. what are people actually keeping vials in? things that seem to matter from what ive read: light protection, not having them rattle aroun…

what does a certificate of analysis actually tell you?
COAs get cited like they settle things and I'm slowly realising they're narrower than people think. What one typically reports: identity (often mass spec, confirms the molecular w…
what would a genuinely convincing study of one of these compounds look like?
Constructive for once. If someone wanted to settle whether one of the popular preclinical compounds does anything, what would it take? My sketch: randomized, placebo controlled, d…
honest take after 2 years of logging: it's a filing system, not an experiment
After a couple of years of keeping one, the value has been almost entirely things I didn't expect. Useful for: reconstructing what I actually did months ago, noticing I'd forgotte…
GIP agonism AND GIP antagonism both seem to work. how?
This is the thing in metabolic pharmacology I find hardest to square. Tirzepatide includes GIP receptor agonism and works. There's separately credible work suggesting GIP receptor…
why is basically everything injected
seems like a lot of friction for something that could presumably be a pill. whats the actual barrier
any cognitive claim needs a blood brain barrier story first
Prerequisite question for this entire category and it's frequently skipped. For a peptide to act centrally it has to reach the brain. The blood brain barrier is selective and most…
bpc 157 oral vs injection, does surviving the stomach actually mean anything?
setting aside whether bpc does anything at all, the route argument is worth separating out because a lot of confusion lives there. case for oral: bpc-157 comes from a gastric prot…
why does everything need the fridge after mixing but not before
dont fully understand this. the powder seems fine at room temp for ages but the second theres liquid in there everyone says fridge immediately. whats the actual difference
how i read the results table in one of these trials (what am i missing?)
A lot of the confusion in this category comes from reading summaries instead of papers, so here's what I look at, in order. 1. The analysis population. Intention to treat vs compl…
csv export, one more time
posting it again because it remains the thing i want most. plain csv is fine, it doesnt need to be clever
feature idea: auto-link glossary terms inside threads
the beginner threads keep re-explaining the same terms. a glossary that auto linked defined terms the first time they show up in a post would save that and help people reading abo…
should research logs be shareable? i can see it both ways
open question rather than a request. for: structured logs are more useful to others than prose writeups, and a shared format would make comparison possible in a way forum posts ne…
Poll: which metabolic compound are you actually following right now?
not which one you think is most important, which one you actually read about. curious if attention matches the discussion volume
is there anything in the recovery category with actual human data?
genuine question. everything i read about here is preclinical and im wondering if ive just missed something
Poll: what was the hardest part of getting started?
trying to work out where the beginner content should focus. be honest
the studies you can't read are the ones that would change your mind
Publication bias means the literature you can read is not a random sample of the research that was done. Null results are less likely to be written up, less likely to be accepted,…
Poll: where do your mixed vials actually live?
curious how much the fridge door thing from the storage thread is actually a live issue. be honest
MMP modulation gets cited constantly, but suppressing MMPs isn't straightforwardly good
MMP modulation shows up in basically every cosmetic peptide claim. Worth noting that MMPs do necessary remodelling work and suppressing them isn't automatically good. And it's all…
reminders you actually act on vs reminders you swipe away
turned most of mine off because they kept firing when i couldnt do anything about them, and once you start swiping them away the habit is gone. what would help me is reminders tha…
what would actually change your mind about your favorite compound?
Worth stating in advance, because a position you can't specify disconfirming evidence for isn't really a position about the world. Mine, for the compounds I'm skeptical about: an …
mixed a vial and its still cloudy, is that normal?
ran the water down the side like everyone says, swirled, let it sit. its been a few minutes and its still not fully clear. is that always a problem or can it just be slow
why do the escalation schedules differ so much between agents?
Comparing published protocols, the escalation intervals differ in ways that don't obviously track half life. Curious whether that's tolerability driven or just historical.
Poll: which category do you actually read most?
trying to work out where the reading attention actually is, which is probably not where the posting volume is
conference abstracts as early signal
Abstracts appear well before papers and often before registries update. Useful as early signal, with the caveat that a meaningful fraction never become full publications. The abst…
which library page most needs expanding?
the compound pages are the thing people land on first. which one is thinnest relative to how much it gets asked about here? my vote is anything in the blend category, since those …
check the in vitro concentration before you take a cell result seriously
In vitro work often uses concentrations way above anything achievable systemically. An effect at 100 micromolar in a dish may be irrelevant if plasma levels reach nanomolar. Worth…
Poll: dark mode or light mode
the only question that matters
web community is noticeably thinner than the app one, is parity planned?
Using both, the app version of the community has things the web one doesn't. Threaded replies display better, and there's no way to report anything on web as far as I can tell. No…
dumb question amnesty thread. ask the thing you think is too basic
No such thing as too basic. If you've been sitting on a question because it seems obvious, this is the place. I'll answer what I can and others will fill in the rest.
