BPC-157 · Tendon repair
Faster tendon healing, in rats
Rats with a cut Achilles tendon healed faster with BPC-157 than untreated rats.[1] A 2025 review of BPC-157 in sports medicine found 35 preclinical studies and 1 clinical study.[2]

Most peptide “research” online is a sales page in disguise. We read the actual studies and summarize them in plain English, with the evidence level and every source linked, so you can make up your own mind.
Most of what you’ll find is selling something
01
Vendor “research” pages
They summarize the studies that help the sale and skip the rest.
02
Animal results told as human ones
A rat study becomes “heals tendons” by the third repost.
03
Forum echo
One anecdote, repeated enough times, starts to sound like evidence.
You end up doing hours of reading and still not knowing what’s actually known.
Compounds
Pick a compound. See what’s actually been studied.
Every compound page starts with what it is, what’s been studied, in what, and how strong that evidence is.
Tendon, gut and wound research, most of it in animals.
Peptides studied for how they change growth hormone release.
From approved drugs with large human trials to compounds still in early research.
Cell-energy and aging research, early and mostly preclinical.
Immune, skin and blend research, plus a few common supplements.
You do the reading. We do it with you.
You’re already doing the reading most people skip. You deserve a source that does it with you, honestly. So every summary here follows the same rules:
- Every claim is cited to the study it came from, with a link.
- Every finding carries its evidence level: cell, animal or human, and how many studies.
- Every page shows a last-reviewed date, and we fix mistakes in public on our corrections log.
- No seller links, no seller names, no sponsored edits. Ads are labeled, and advertisers never see an article before it’s published.
The plan
How it works
1
Pick a compound.
Start from the group that fits your question.
2
See the evidence.
What’s been studied, in what, how strong it is, and every source linked.
3
Bring your questions to other researchers.

Peptide research, explained without the sales pitch
Peptide Researcher Studies is an independent library of plain-English summaries of published peptide research. We cover the compounds people ask about most, from BPC-157 and TB-500 to growth hormone secretagogues, GLP-1 drugs and longevity research.
Each compound page answers the same questions in the same order: what the compound is, what has been studied, whether those studies were done in cells, animals or people, what the studies gave their subjects and for how long, what side effects were reported, its legal and approval status, and what is still unknown. When the only evidence is a handful of rat studies, we say so in the first line, not the last.
We don’t sell peptides, link to sellers or name them. If you’re researching where compounds come from, our guide to what to look for covers third-party testing, certificates of analysis and the red flags worth knowing. If a study is new to you, start with how to read a peptide study.
Nothing here is medical advice, and we don’t publish personal dosing. When a study used a dose, we report it as part of that study’s method so you can see what was actually tested. Questions about using a compound belong with your doctor; questions about the research belong in our forum, which opens once 100 researchers join the waitlist. Read how we choose, cite and review studies on our editorial standards page, or learn more about us.
Know what’s known, and show the study that says so.
