Ground Truth Peptides

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.

The sources we watch

25 live · expanding to ~30

Independent science

Conflict-free evidence grading of compounds.

No ads, no sales, no sponsorships, the gold standard for what the evidence actually says.

Substack · @EricTopol

Cardiologist; wrote 'The Peptide Craze.'

A leading academic directly critiquing the hype cycle, keeps us honest about the gaps.

Science communication; debunks biohacker claims.

Best-in-class myth-busting to separate signal from marketing.

Web · @foundmyfitness

Evidence-based aging & supplement science.

Rigorous, citation-heavy, generally product-agnostic.

Clinician

Web · @AbudBakri

Peptides, hormones, circadian; Huberman guest (2026).

Our lead authority, the animal-vs-human-gap framing the whole site rests on.

Web · @konivermd [verify]

Performance medicine; the peptide doctor on Huberman's Oct 2024 episode.

The Huberman guest you were thinking of, track him, but he prescribes and sells these therapies.

⚑ Conflict: Runs a practice that prescribes/sells the therapies he discusses.

Web · @PeterAttiaMD

Longevity; did a full AMA on gray-market peptides.

Cautious and mechanism-first, a model of the nuance this page wants.

Dr. Kyle Gillett. Gillett Healthunverified

YouTube · @GillettHealth

Hormones, peptides; 'hype vs. misinformation' framing.

Dual board-certified; explicitly addresses peptide misinformation.

⚑ Conflict: Runs Gillett Health (labs/consults), minor.

Dr. Ben Bikmanunverified

Podcast · @benbikmanphd [verify]

Metabolic scientist; peptides & metabolism, GLP-1 mechanism.

Academic physiologist explaining mechanism, not selling.

Communicator

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.

Paul Saladino, MDunverified

@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).

Mike O'Hearnunverified

@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.

Dr. Mike Israetel. Renaissance Periodizationunverified

@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.

Chris Bumsteadunverified

@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.

Dorian Yatesunverified

@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

Gary Brecka. 10X Healthunverified

@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.

DTC telehealth peptide brandsunverified

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.

Saved searches per compound

Primary literature on every compound we grade.

The actual evidence base, alerts so we cite new human studies the day they post.

Regulatory

Advisory committee calendar

503A bulks reviews of BPC-157, TB-500, KPV, MOTS-c, more. Jul 23–24, 2026.

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.

Jul 23–24, 2026Regulatory

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.

Recent updates

Jun 2026

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.

Jun 2026

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.

Jun 2026

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.

See who the people behind these sources are on the authorities page, or ask us something on the questions page.
