Growth Hormone

Peptalix Labs supplies the best growth hormone peptides for laboratory and scientific research, covering the GHRH-receptor, ghrelin-receptor, and IGF-1 signalling pathways most studied in GH-axis research. Our growth hormone category includes GHRH analogues, selective GH secretagogues, and extended-half-life growth factor compounds — each independently batch-tested for purity and identity, GMP-sourced, and lyophilised for maximum stability.

What Are Growth Hormone Research Peptides?

Growth hormone research peptides are compounds studied for their influence on the GH/IGF-1 axis — the hormonal cascade running from hypothalamic GHRH release through pituitary GH secretion to downstream IGF-1 signalling. Compounds such as Sermorelin act directly on GHRH receptors, while IGF-1 LR3 studies the downstream growth-factor signalling stage.

Our Growth Hormone Peptide Range

The Peptalix Labs growth hormone category includes: Sermorelin 10mg — GHRH(1-29) analogue studied for pulsatile GH release IGF-1 LR3 1mg — extended half-life IGF-1 analogue for downstream signalling research Tesamorelin + Ipamorelin Blend 16mg — combined GHRH analogue and selective GH secretagogue research stack

Quality Standards for Every Growth Hormone Peptide

Single-compound products in this category are tested by Freedom Diagnostics using HPLC-UV with mass spectrometry. The Tesamorelin + Ipamorelin blend undergoes a more comprehensive full QC panel via ILS Laboratories (ISO/IEC 17025 accredited), including heavy metals analysis and fentanyl screening. Certificates of Analysis are published per batch for full transparency.

Shipping Growth Hormone Research Peptides

Peptalix Labs ships all growth hormone research peptides same-day from our USA facility on orders placed before the daily cut-off. International shipping is available to Canada, Australia, the United Kingdom, and most of Europe, with tracked delivery on every order. Research Use Only. All growth hormone peptides listed in this category are supplied strictly for in-vitro laboratory and scientific research. Tesamorelin is an FDA-approved active pharmaceutical ingredient (marketed as Egrifta), however Peptalix Labs supplies it strictly for research use, not for clinical or human use.

Frequently Asked Questions — Growth Hormone Research Peptides

What is the best growth hormone peptide for research?

There is no single "best" compound — the right choice depends on which stage of the GH/IGF-1 axis is being studied. Sermorelin targets GHRH-receptor-mediated GH release, while IGF-1 LR3 studies the downstream growth-factor signalling stage. Many researchers study both stages in parallel.

What is the difference between Sermorelin and Ipamorelin?

Sermorelin is a GHRH analogue that stimulates the pituitary's GHRH receptor directly. Ipamorelin is a selective GH secretagogue acting through the ghrelin receptor pathway. Both are studied for GH stimulation but through distinct receptor mechanisms.

Is Tesamorelin FDA-approved?

Yes. Tesamorelin is an FDA-approved active pharmaceutical ingredient, marketed as Egrifta for clinical use. Peptalix Labs supplies research-grade Tesamorelin (within our blend product) strictly for in-vitro laboratory research.

What purity level do Peptalix Labs growth hormone peptides have?

All growth hormone peptides in this category are independently batch-tested at 99%+ purity. Standard products are tested by Freedom Diagnostics via HPLC-UV and mass spectrometry; the Tesamorelin + Ipamorelin blend undergoes a more comprehensive full QC panel via ILS Laboratories.

What is IGF-1 LR3 and how does it differ from native IGF-1?

IGF-1 LR3 is a modified analogue of insulin-like growth factor 1 with reduced binding affinity to IGF-binding proteins, extending its biological half-life in research models compared to native IGF-1.

How are growth hormone research peptides stored?

All growth hormone peptides are supplied as lyophilised powder and should be stored at -20°C prior to reconstitution. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 28 days.

Does Peptalix Labs ship growth hormone peptides internationally?

Yes. All growth hormone research peptides ship same-day from our USA facility, with international delivery available to Canada, Australia, the United Kingdom, and most of Europe.

Can Sermorelin and IGF-1 LR3 be studied together?

Yes. Since they act at different stages of the GH/IGF-1 axis — Sermorelin upstream at the GHRH receptor and IGF-1 LR3 downstream at the growth-factor signalling stage — many researchers study them in parallel for comprehensive axis-wide research.
