Question 1

What are peptides?

Accepted Answer

Peptides are short chains of amino acids (typically 2–50) linked by peptide bonds. They act as signaling molecules in the body, influencing processes like growth, metabolism, immune function, and tissue repair.

Question 2

How do peptides work in the body?

Accepted Answer

Peptides bind to specific receptors on cell surfaces, triggering biological responses. For example, growth hormone-releasing peptides (GHRPs) stimulate the pituitary gland to produce more growth hormone.

Question 3

What's the difference between peptides and proteins?

Accepted Answer

The main difference is size. Peptides contain 2–50 amino acids, while proteins contain 50 or more. Proteins have complex 3D structures, while peptides are simpler chains.

Question 4

Are peptides natural?

Accepted Answer

Yes! Your body naturally produces thousands of peptides. Insulin, oxytocin, and endorphins are all peptides. Research peptides are synthetic versions designed to mimic or enhance these natural signaling molecules.

Question 5

Are peptides legal?

Accepted Answer

It varies by country and peptide. In the US, many peptides are legal to purchase for research purposes only but not approved for human consumption. Some peptides like semaglutide are FDA-approved prescription drugs.

Question 6

Are peptides safe?

Accepted Answer

FDA-approved peptides have well-established safety profiles when used as prescribed. Research peptides have less safety data but tend to have fewer side effects than traditional pharmaceuticals.

Question 7

Can you take multiple peptides at once?

Accepted Answer

Yes, this is called stacking and is common practice. Many peptides work synergistically. However, stacking increases complexity and potential for interactions.

Question 8

How do I reconstitute a peptide?

Accepted Answer

Most peptides come as lyophilized powder. Reconstitute with bacteriostatic water: inject slowly into the vial aiming at the glass wall, then gently swirl until dissolved.

Question 9

How should I store peptides?

Accepted Answer

Unreconstituted: refrigerate (2–8°C) for up to 2 years. Reconstituted: always refrigerate and use within 4–6 weeks. Never freeze reconstituted peptides.

Question 10

What's the best peptide for beginners?

Accepted Answer

It depends on your goals. Common beginner choices include BPC-157 for healing, CJC-1295/Ipamorelin for growth hormone optimization, GHK-Cu for skin, and Selank for cognition.

Question 11

How long until I see results?

Accepted Answer

Timeline varies: GLP-1 agonists 2–4 weeks, BPC-157 1–2 weeks for healing, growth hormone peptides 4–8 weeks for body composition, skin peptides 4–12 weeks.
