What are peptides?

Introduction to Peptides

Your Body. Optimised by Science.
At Reviva, we specialise in cutting-edge peptide therapy designed for modern health goals—from fat loss and muscle preservation to skin rejuvenation and injury recovery. But what exactly are peptides, and why are they gaining so much attention in the world of performance and longevity medicine?

What Are Peptides?

Peptides are short chains of amino acids—natural building blocks of proteins in the body. They act as cellular messengers, triggering specific biological responses that help regulate metabolism, repair tissue, promote healing, support immune function, and more.

Each peptide has a unique role. Below, we introduce some of the most powerful and well-researched peptides available in our Reviva Pen range—engineered for precision, stability, and everyday use.

Retatrutide

Metabolism • Fat Loss • Muscle Retention

Retatrutide is a next-generation multi-receptor peptide that targets GLP-1, GIP, and glucagon pathways—all of which are involved in appetite regulation, insulin sensitivity, and energy balance. Unlike older treatments like Ozempic or Mounjaro, Retatrutide not only supports significant fat loss, but also helps preserve lean muscle mass during weight reduction.

Ideal for:

  • Weight management

  • Metabolic reset

  • Body recomposition

  • Appetite control with less muscle loss

GHK-Cu (Copper Peptide)

Skin Repair • Anti-Ageing • Hair Health

GHK-Cu is a naturally occurring copper-binding peptide known for its powerful regenerative and anti-inflammatory properties. It stimulates collagen production, promotes wound healing, improves skin elasticity, and supports hair growth by nourishing hair follicles at the cellular level.

Ideal for:

  • Skin rejuvenation and anti-ageing

  • Scar and wound repair

  • Hair thinning and scalp health

  • Cellular renewal

TB-500 (Thymosin Beta-4 Fragment)

Recovery • Performance • Muscle Repair

TB-500 is a synthetic peptide that mimics the effects of Thymosin Beta-4, a naturally occurring protein involved in tissue regeneration and inflammation reduction. It enhances cellular migration and blood flow to damaged tissues, making it highly effective for injury recovery, muscle repair, and joint health.

Ideal for:

  • Athletic recovery

  • Muscle or ligament injuries

  • Inflammation reduction

  • Improved flexibility and mobility

BPC-157 (Body Protection Compound)

Gut Health • Healing • Joint Support

BPC-157 is a powerful peptide originally isolated from human gastric juice. It supports gut lining repair, speeds up wound healing, and is widely known for its role in joint and tendon recovery. Unlike typical medications that treat symptoms, BPC-157 works at the root level by accelerating the body’s natural repair mechanisms.

Ideal for:

  • Leaky gut and digestive issues

  • Soft tissue injuries

  • Tendon, ligament, or joint support

  • Overall systemic healing
