Peptides, without the jargon
What peptides are made from, how they act as biological signals, and why different peptides can produce very different effects.
8 min
Peptide Academy
Start knowing nothing.
Finish understanding peptides.
Peptides can influence some of the most interesting signalling systems in the body, from appetite and metabolism to recovery, collagen, growth-hormone signalling, sexual function, cognition and cellular energy. Peptide Academy starts with the big picture, then teaches you how to actually use the information.
Already know the basics?
Jump straight to the tool or reference you need. If you are using a pen, read the pen instructions before using click calculations because devices are not interchangeable.
Important before using a peptide pen
Pen concentration, click scale and mechanism can differ between devices. Never carry a click count from one pen to another. Confirm the exact device and click scale first, then use the calculator only to convert inputs you already know.

Part 1 · Learn the framework
Build the comparison framework first.
Learn families, comparison logic, blends and the repeatable deep-dive method before applying it to individual compounds.

12 min
08
How to compare peptides without the hype
Compare target, evidence, route, formulation and outcome instead of asking which peptide is simply ‘better’.
11 min
09
Single peptides, blends & stacking
Why combining compounds changes the evidence question, makes attribution harder and should not be treated as simple addition.
11 min
10
How to deep-dive an individual peptide
Use one repeatable framework to understand a peptide from mechanism and evidence through formulation, outcomes, uncertainty and the questions that still need answering.
13 min
Part 2 · Evidence-first case studies
Apply the framework to real peptides.
Six deliberately different case studies show how the same evidence-first method changes when the evidence is strong, mixed, early, formulation-specific or combination-based.
11
Semaglutide: an evidence-first deep dive

15 min
12

14 min
13
BPC-157: an evidence-first deep dive
Use BPC-157 to understand how a broad preclinical literature, a small number of human observations and strong online interest can coexist without proving clinical efficacy.
15 min
14
Tesamorelin: an evidence-first deep dive
Use tesamorelin to learn why an approved peptide can have strong human evidence while still having a deliberately narrow indication and product-specific context.
14 min
15
GLP-3 Retatrutide: an evidence-first deep dive
Explore one of the most exciting metabolic peptide research programmes while separating peer-reviewed Phase 2 evidence, positive Phase 3 results and the remaining regulatory steps.
16 min
16
CJC-1295 / Ipamorelin: an evidence-first deep dive
Learn why CJC-1295 DAC, CJC no DAC and ipamorelin must be separated, and why evidence for two components does not validate a popular combination protocol.
15 min
Part 3 · Compare & synthesize
Step back from individual compounds.
Finish the level by comparing peptide families and learning how to evaluate claims without letting mechanism, hype or one exciting result outrun the evidence.
17
How to compare peptide families
Compare signalling families by target, biological system, evidence, endpoints and delivery instead of treating every peptide aimed at the same goal as equivalent.
12 min
18
How to evaluate peptide evidence without hype
Quickly separate mechanism, animal data, human outcomes, effect size, uncertainty and marketing language so an exciting claim stays interesting without becoming stronger than the evidence.
