'Ascension' Bundle

Ascension Bundle — Retatrutide, Melanotan II and GHK-Cu Research Peptide Kit

The Ascension Bundle is a triple-peptide research kit combining three compounds from three research categories in one order: a 10mg vial of Retatrutide, the investigational GIP, GLP-1 and glucagon receptor triple agonist often shortened to reta; a 10mg vial of Melanotan II, the cyclic alpha-MSH analogue written as MT2 or melanotan 2; and a 50mg vial of GHK-Cu, the copper-binding tripeptide also called copper peptide or copper tripeptide-1. Researchers usually search for it as the Ascension bundle or a retatrutide melanotan ghk-cu bundle; the sterile supplies for reconstitution are packed with the vials.

Retatrutide is studied in metabolic research for energy balance, glucose handling and hepatic fat; its 39-amino-acid GIP-based backbone carries a C20 fatty diacid that binds albumin and extends its half-life to roughly six days. Melanotan II is investigated in melanocortin research as a non-selective agonist at the MC1, MC3, MC4 and MC5 receptors. GHK-Cu is studied in skin, collagen and wound-healing models, where it delivers copper to cells and modulates the expression of genes involved in extracellular-matrix remodelling.

Omega Peptides Australia supplies all three as high-purity (≥99% HPLC), COA-verified lyophilised powders in sealed sterile vials, dispatched same day from within Australia on orders placed before 12pm, with each batch Certificate of Analysis available in the COA library.

What is included

• 1 × Retatrutide 10mg vial, lyophilised powder in a sealed sterile vial ($159.99 individually).
• 1 × Melanotan II (MT2) 10mg vial, lyophilised powder ($79.99 individually).
• 1 × GHK-Cu 50mg vial, lyophilised copper-peptide powder ($89.99 individually).
• 1 × 10mL bacteriostatic water, sterile water with 0.9% benzyl alcohol ($29.99 individually).
• 10 × 1mL insulin syringes, individually sealed, fixed needle (10 pack $19.99 individually).
• 4 × alcohol swabs for cleaning vial stoppers before each puncture.

Key research areas

• Metabolic and energy-balance research (Retatrutide). The most clinically advanced triple incretin agonist, with Phase 2 and Phase 3 programmes reporting large, dose-dependent reductions in body weight. The glucagon-receptor component is thought to add energy expenditure and hepatic effects to GLP-1 and GIP appetite signalling.
• Glucose and liver-fat research (Retatrutide). GIP and GLP-1 receptor activation enhances glucose-dependent insulin release, and imaging sub-studies in the clinical programme have measured liver-fat content in steatotic liver disease research.
• Pigmentation research (Melanotan II). MC1R activation on melanocytes raises cyclic AMP, activates MITF and upregulates tyrosinase, shifting melanin synthesis toward eumelanin. MC4R activation is separately studied for appetite and sexual-arousal signalling.
• Skin and collagen research (GHK-Cu). First isolated from human plasma by Loren Pickart in 1973, GHK-Cu stimulates collagen and glycosaminoglycan synthesis in fibroblast cultures and has been studied for wound contraction and angiogenesis in animal models.
• Gene expression and tissue remodelling (GHK-Cu). Gene-array studies report that GHK-Cu modulates a large number of human genes, including metalloproteinases and their inhibitors, decorin and growth factors such as VEGF, underpinning its use in extracellular-matrix and antioxidant research.

Why these are supplied together

The three peptides cover metabolic, melanocortin and dermal research but share identical handling: each arrives lyophilised, is reconstituted with bacteriostatic water, and is refrigerated once in solution. Supplying one 10mL vial of bacteriostatic water, ten 1mL syringes and alcohol swabs with the three vials means every compound is reconstituted with a diluent of known composition, with volume to spare.

Retatrutide and Melanotan II both signal through G-protein-coupled receptors that raise cyclic AMP, and incretin and melanocortin pathways intersect in the hypothalamic control of energy balance, so the two are natural comparators. GHK-Cu adds a tissue-level compound: laboratories studying how rapid changes in adiposity affect skin structure, dermal collagen and wound repair pair it with metabolic agents to examine extracellular-matrix remodelling.

Specifications

Available sizes and pricing

The Ascension Bundle comes in one configuration. Bought separately, the three peptide vials, 10mL bacteriostatic water and a 10 pack of syringes total $379.95, so the bundle saves about $50 and includes the swabs. Researchers who do not need GHK-Cu can choose the Retatrutide + Melanotan 2 Starter Bundle at $269.99.

• Ascension Bundle, $329.99 (about $16.00, $8.00 and $1.80 per mg for Retatrutide, Melanotan II and GHK-Cu when priced individually, supplies included)

Quality and COA verification

Every peptide batch in the Ascension Bundle is tested independently by Janoshik Analytical: HPLC confirms purity at or above 99% and mass spectrometry confirms identity against the expected molecular weight. A Certificate of Analysis is issued for every batch and published in the COA library. All three peptides are lyophilised in sealed sterile vials for stability in storage and domestic transit, and the kit is packed with the diluent and syringes secured separately.

Frequently bought together

• Retatrutide + Melanotan 2 Starter Bundle, $269.99, the same kit without GHK-Cu for metabolic and melanocortin work alone.
• GHK-Cu (100mg), $119.99, a larger vial at a lower per-mg cost for extended skin and collagen studies.
• Melanotan II (10mg), $79.99, a second MT2 vial for parallel melanocortin assays.
• Bacteriostatic Water (10mL), $29.99, a spare diluent vial for repeat reconstitutions.

Frequently asked questions

What is in the Ascension Bundle?
One 10mg Retatrutide vial, one 10mg Melanotan II vial and one 50mg GHK-Cu vial, all lyophilised powders in sealed sterile vials, plus one 10mL vial of bacteriostatic water, ten 1mL insulin syringes and four alcohol swabs, for $329.99. Compared with the Retatrutide + Melanotan 2 Starter Bundle, the only difference is the GHK-Cu vial, which adds a skin and collagen research compound to the metabolic and melanocortin pair.

What is Retatrutide?
Retatrutide (LY3437943) is a synthetic 39-amino-acid peptide designed as a single-molecule agonist of the GIP, GLP-1 and glucagon receptors. A C20 fatty diacid on the backbone binds albumin, giving a half-life of about six days. It is an investigational Phase 3 compound studied in metabolic research models for energy balance, glucose regulation and hepatic fat.

Do I need bacteriostatic water and syringes?
Yes. All three peptides arrive as dry lyophilised powder and must be dissolved before any laboratory procedure. Bacteriostatic water is the recommended diluent because its 0.9% benzyl alcohol inhibits bacterial growth across repeated vial punctures. The 10mL vial, ten sterile 1mL syringes and four swabs supplied here cover all three vials.

How much do I save with the bundle?
Purchased separately, Retatrutide 10mg is $159.99, Melanotan II 10mg $79.99, GHK-Cu 50mg $89.99, 10mL bacteriostatic water $29.99 and a 10 pack of 1mL syringes $19.99, a total of $379.95. The Ascension Bundle is $329.99, a saving of about $50, with the alcohol swabs included at no charge.

Can I buy the items separately?
Yes. Retatrutide is listed in 5mg to 60mg vials, Melanotan II in a 10mg vial, GHK-Cu in 50mg and 100mg vials, bacteriostatic water in 3mL and 10mL vials, and 1mL syringes in 5 and 10 packs. Buying separately suits laboratories that already hold diluent and syringes; the bundle suits a first order.

Can I buy Retatrutide at Chemist Warehouse or a pharmacy in Australia?
No. Retatrutide is an investigational Phase 3 compound not approved by the TGA, the FDA or any other regulator, and Melanotan II is not an approved medicine in Australia, so neither is stocked by Chemist Warehouse, Priceline or other retail pharmacies. Some cosmetic serums sold in pharmacies list copper peptides as a topical ingredient; those are cosmetics, not the research-grade lyophilised GHK-Cu supplied here.

Can Australian compounding pharmacies supply Retatrutide?
Retatrutide is not a registered medicine in Australia. Compounding pharmacies may only prepare a product for an individual patient against a prescription, and any such preparation is a separate product from the research compound sold here. Omega Peptides Australia supplies the lyophilised research compounds for in-vitro laboratory use only and does not compound medicines.

How do you reconstitute the peptides in the Ascension Bundle?
Wipe both stoppers with an alcohol swab. Draw the required volume of bacteriostatic water into a 1mL syringe and add it slowly down the inside wall of the peptide vial, not onto the powder. Swirl gently until clear; never shake. Reconstituted GHK-Cu is a distinct blue solution. Label each vial, refrigerate at 2–8°C and use within 28 days.

How should the peptides in this bundle be stored?
Keep the lyophilised vials sealed at 2–8°C short term or −20°C long term, protected from light and moisture, and avoid repeated freeze-thaw cycles. Once reconstituted, store all three peptides at 2–8°C and use within 28 days. Bacteriostatic water is kept at room temperature and discarded 28 days after the first puncture.
