Question 1

What are peptides?

Accepted Answer

Peptides are short chains of amino acids that act as biological messengers in the body, signaling cells to perform specific functions like healing tissue, burning fat, building muscle, or balancing hormones.

Question 2

What is the difference between semaglutide and tirzepatide?

Accepted Answer

Semaglutide is a GLP-1 receptor agonist that reduces appetite and slows gastric emptying. Tirzepatide is a dual GLP-1/GIP receptor agonist that activates two pathways, leading to greater average weight loss in clinical trials (up to 22% body weight).

Question 3

Do I need a prescription for GLP-1 medications?

Accepted Answer

Yes. GLP-1 medications like semaglutide and tirzepatide require a valid prescription from a licensed practitioner. Health Collective works exclusively with licensed physicians and FDA-compliant compounding pharmacies.

Question 4

How long does it take to see results from peptide therapy?

Accepted Answer

Results vary by peptide and goal. GLP-1s typically show noticeable appetite reduction within 1-2 weeks, with meaningful weight loss in 4-8 weeks. Healing peptides like BPC-157 can show improvements in 2-4 weeks. Most protocols are designed for 8-16 week cycles.
