Peptides vs. Supplements vs. Hormones: What’s the Difference?
Understanding the Wellness Toolbox
Peptides, supplements, and hormones all play a role in optimizing the body — but they’re not the same thing.
At Peptara, we believe in educating and empowering you to understand how these tools differ so you can make informed decisions in your wellness journey. Here’s how each category works:
What Are Peptides?
Peptides are short chains of amino acids that send messages in the body — acting as messenger molecules that may trigger regeneration, fat burning, cellular repair, or hormone signaling.
They’re often referred to as “biohackers in a bottle” because they can nudge your body toward a specific function, like deeper sleep or better recovery — without replacing a hormone or nutrient.
- Function: Activate natural systems already present in the body
- Format: Research compounds (not supplements or medications)
- Examples: BPC-157, CJC1295, Epitalon, GHK-Cu
- How they work: Mimic or stimulate natural signaling peptides
What Are Supplements?
Supplements are nutrients or compounds you consume to support the body’s daily needs or optimize specific processes.
Think vitamins, minerals, adaptogens, and botanicals — used to nourish, stabilize, or rebalance.
- Function: Replenish or support nutritional systems
- Format: Capsules, powders, tablets (regulated differently than drugs)
- Examples: Vitamin D, Magnesium, Ashwagandha, Omega-3s
- How they work: Fill in gaps or boost natural functions

What Are Hormones?
Hormones are chemical messengers like testosterone, estrogen, or thyroid hormone that regulate key systems in the body. Hormone therapy involves replacing or adjusting your body’s hormone levels.
Unlike peptides or supplements, hormones are regulated medical treatments and must be prescribed by licensed providers.
- Function: Replace or regulate core physiological levels
- Format: Prescription only (injections, patches, pills)
- Examples: Testosterone, Estrogen, Progesterone, Thyroid medication
- How they work: Direct hormone replacement to manage imbalances
