The freshness engine
What we track, and when.
Saying "constantly updated" means nothing unless you can see the process. So here it is. The sources we watch, how often, and why. Come here when something just dropped and you want to know what it actually says.
Daily
PubMed alerts per compound + new independent-lab batch data.
New human data and new failed-batch reports are the two things that can change a grade overnight.
Weekly
The voices below, scientists, clinicians, communicators, the fitness community, and verifiable social.
This is where claims spread before they're studied. We watch it so we can debunk or corroborate fast, and say which it is.
Monthly
Regulatory status (FDA · PCAC · Federal Register · Warning Letters) and the competitive landscape.
What's legal and compoundable changes what you can actually get. PCAC reviews BPC-157, TB-500, MOTS-c and more on Jul 23–24, 2026.
Every item is triaged one of three ways, update a profile, open a new one, or kill it as noise, and logged with its source and a credibility tag. So a change to a grade can always be traced back to why.

Academic physiologist explaining mechanism, not selling.
Communicator
@hubermanlab
Two dedicated peptide episodes (Koniver 2024, Bakri 2026).
The single biggest driver of mainstream peptide interest, what he covers becomes next week's search traffic.
@paulsaladinomd
Animal-based/carnivore health; metabolic & hormone takes.
Huge reach; not a peptide specialist, track the narrative, weigh the conflict.
⚑ Conflict: Founder of Heart & Soil supplements; sells products he promotes.
Web · @tferriss
Early peptide-curious podcaster; experimentation framing.
Cultural bellwether for biohacking topics crossing mainstream.
Community & fitness
YouTube · @moreplatesmoredates
The most technically detailed lay coverage of peptides/TRT.
Genuinely the deepest community explainer, treat claims as Grade D until corroborated.
⚑ Conflict: Co-owns Marek Health (TRT clinic) and Gorilla Mind (supplements).
@mikeohearn
Bodybuilding; BPC-157/TB-500 recovery content.
Best match for the 'Michael Hearn' you named, confirm. Track for what's trending in the fitness world.
⚑ Conflict: Hosts industry sponsors; recovery-peptide promotion.
@drmikeisraetel
Sport-physiology PhD; candid PED/peptide commentary.
Science-trained and blunt about what peptides do and don't do for muscle.
⚑ Conflict: Co-owns RP (programs/supplements), minor.
@cbum
Classic Physique Mr. Olympia (recently retired); recovery, TRT, and what the elite-physique world actually runs.
Enormous reach at the very front of physique performance, track what the top of the sport adopts before anyone else.
⚑ Conflict: Sells programs / supplements; promotes within the industry.
@thedorianyates
Six-time Mr. Olympia, HIT pioneer; unusually candid about PEDs, recovery and post-career health.
A historical authority, performance enhancement has run through bodybuilding for decades, and he's one of its most honest narrators.
⚑ Conflict: Sells training programs + a supplement line.
Conflicted commercial
@garybrecka
Sermorelin, CJC-1295+Ipamorelin, NAD+; aggressive promotion.
High-influence hype driver, track to know what claims we'll be asked to fact-check.
⚑ Conflict: Sells the peptides he promotes; FDA-flagged compounds; debunked by McGill OSS.
Web/IG (Marek, Peptual, etc.)
Direct-to-consumer marketing & dosing claims.
The front line of consumer messaging, a 'what's being sold and how it's framed' signal.
⚑ Conflict: Sell what they market.
Data & labs
Third-party purity/quantity testing; COA verification.
The default independent lab, the reference for 'is this vial real.'
Independent vendor testing (8,000+ tests, 225+ vendors).
Anecdote's antidote, independent, at scale. Trust agreement across two labs.

On the calendar
The regulatory votes and the trials that could actually move a grade. This is our "let's see what it says" list. Stuff we're genuinely watching.
FDA PCAC reviews 7 peptides
The advisory committee weighs whether BPC-157, TB-500, MOTS-c, KPV, DSIP, Semax and Epitalon can be legally compounded, the single most consequential vote for peptide legality. We'll re-grade the moment it lands.
Track it ↗Five more peptides to PCAC
A second tranche of restricted peptides is scheduled for advisory review before the end of February 2027.
Track it ↗GHK-Cu moves toward Category 1
GHK-Cu is the first restricted peptide moving back toward compoundable status, a possible template for the rest.
Track it ↗MOTS-c, first-in-human (Phase 1)
The very first human trial of MOTS-c, registered in 2026, has no results yet. When it reports, MOTS-c could leave 'animal only' for the first time.
Track it ↗BPC-157. Phase II efficacy
A registered controlled trial that, if completed, would be the first real human efficacy data for BPC-157, currently its biggest blank.
Track it ↗Retatrutide, the triple agonist
The 'triple-G' agonist posted roughly 24% weight loss in Phase 2; its Phase 3 outcome trials are the readout to watch, and would reset the bar.
Track it ↗Tesamorelin beyond HIV
Trials extending tesamorelin's liver-fat (NAFLD/MASH) evidence beyond the HIV population it's currently approved in.
Track it ↗Recent updates
Launched the four-lens Ground Truth Score.
A single grade hid the real question. Proven for what? We split it into science, real-world signal, safety, and placebo risk so you can see exactly where the confidence lives.
Re-verified every external citation on the site.
A source you can't open isn't a source. We dropped dead links and replaced them with ones that actually resolve.
Reflected BPC-157 and TB-500 coming off FDA Category 2.
Regulatory status changes what's compoundable. So it changes the safety and access picture on the profile.
