Ten questions everyone asks first
The plain-language primer. If you're new to peptides, start here: then graduate to the education library.
- 1
What exactly is a peptide?
A peptide is a chain of amino acids connected by peptide bonds. Different amino-acid sequences create peptides with very different biological properties.
- 2
What's the difference between peptides and amino acids?
Amino acids are the individual building blocks. Peptides are created when amino acids link together.
- 3
Are all peptides the same?
Not even close. Different peptides can interact with completely different receptors and biological pathways.
- 4
Are peptides steroids?
No. Peptides and steroid hormones are chemically different classes of molecules.
- 5
Are all peptides FDA-approved?
No. Some peptide-based drugs are FDA-approved, while others remain investigational or are being studied for different uses.
Keep asking
Clear questions make complicated science easier to navigate.
- 6
Do peptides actually work?
That depends entirely on the specific peptide and the outcome being studied. Evidence ranges from extensive human clinical trials to preliminary laboratory research.
- 7
Are peptides only injectable?
No. Delivery depends on the molecule and formulation. Peptide-related medications and products can use different delivery systems.
- 8
What is a peptide stack?
“Stacking” generally means combining multiple compounds around a particular goal. More compounds don't automatically mean better outcomes.
- 9
What's a COA?
A Certificate of Analysis reports specific testing performed on a sample or batch. Always look at exactly what was tested: not just whether a COA exists.
- 10
How do you evaluate peptide research?
Look at whether the evidence comes from laboratory studies, animal studies, human observational research, randomized clinical trials, or regulatory review.
