💡 What Are Peptides?

Peptides are short chains of amino acids that act as natural “messengers,” signaling the body to perform specific functions—like repairing cells, releasing hormones, or improving metabolism.


🔋 What is NAD+?

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell of your body. While not technically a peptide, it’s often included in peptide therapy programs because of its essential role in energy and cellular repair.

✅ Reported Benefits:

  • Boosts cellular energy and metabolism

  • May improve mental clarity and focus

  • Supports healthy aging and DNA repair

  • Aids detox and recovery from stress or illness

💉 How to Inject:

  • Dosage: As prescribed by your provider (typically 1–2 times per week)

  • Injection Type: Subcutaneous (under the skin)

  • Injection Site: Belly area (about 2 inches from the navel), thigh, or back of upper arm


💤 What is Sermorelin?

Sermorelin is a peptide that encourages your pituitary gland to naturally release more growth hormone (GH), especially while you sleep.

✅ Reported Benefits:

  • May improve deep, restorative sleep

  • Supports muscle tone and fat metabolism

  • Promotes skin firmness and recovery

  • Enhances energy, endurance, and recovery

💉 How to Inject:

  • Dosage: Typically taken nightly before bed

  • Injection Type: Subcutaneous

  • Injection Site: Belly area or thigh (rotate sites if injecting regularly)


✨ What is Glutathione?

Glutathione is a master antioxidant found in every cell. It helps detox the body, brighten the skin, and reduce inflammation.

✅ Reported Benefits:

  • Supports liver detox and immune health

  • May reduce oxidative stress and inflammation

  • Promotes clearer, more radiant skin

  • Aids in tissue repair and recovery

💉 How to Inject:

  • Dosage: As directed by your provider (typically weekly or biweekly)

  • Injection Type: Subcutaneous

  • Injection Site: Same as above—abdomen or thigh
