Tesamorelin + Ipamorelin

Tesamorelin & Ipamorelin Blend (5mg + 5mg)

The Tesamorelin & Ipamorelin combination is a synergistic peptide blend designed to enhance growth hormone (GH) secretion, support metabolic function, and optimize body composition.

By combining a GHRH analog (Tesamorelin) with a selective ghrelin receptor agonist (Ipamorelin), this dual-action formula promotes natural GH pulsation while maintaining hormonal stability.

This advanced combination targets both growth hormone release pathways, resulting in a more efficient and physiologically balanced stimulation of GH and IGF-1 production.

Mechanism of Action

Tesamorelin stimulates the pituitary gland to increase endogenous growth hormone production through GHRH receptor activation.

Ipamorelin works by selectively activating ghrelin receptors (GHS-R1a), enhancing GH release without significantly affecting cortisol or prolactin levels.

Together, they provide:

• enhanced GH pulse amplitude and frequency

• improved anabolic signaling

• optimized metabolic activity

After Reconstitution:

Store in the refrigerator (2–8 °C / 36–46 °F) and use within 30 days for optimal results.

Research Overview

1. Growth Hormone Optimization

This combination enhances natural GH secretion, supporting:

• increased IGF-1 production

• improved protein synthesis

• enhanced metabolic regulation

2. Fat Metabolism & Body Composition

Tesamorelin is widely studied for its role in:

• reducing visceral fat

• improving lipid metabolism

• supporting lean body composition

Combined with Ipamorelin, this may enhance fat utilization while preserving muscle mass.

3. Recovery & Tissue Repair

Research suggests this blend may:

• accelerate muscle and tissue recovery

• support collagen synthesis

• improve post-exercise regeneration

4. Sleep & Recovery Cycles

Growth hormone is closely linked to deep sleep phases.

This combination may:

• improve sleep quality

• enhance deep sleep duration

• support overnight recovery processes

5. Hormonal Stability

Ipamorelin provides selective GH stimulation without significantly increasing:

• cortisol

• prolactin

This contributes to a more controlled and balanced hormonal response.

6. Longevity & Metabolic Health

Tesamorelin & Ipamorelin are studied for their role in:

• maintaining metabolic efficiency

• supporting cellular regeneration

• reducing age-related decline in GH production
