Vial kit. Retatrutide (RT GLP-3) 30 mg, Cagrilintide 20 mg, Tesamorelin 20 mg and Bacteriostatic Water 10 ml. For laboratory research use only.

Retatrutide (RT GLP-3)30 mg

RETAKLIK contains Reta-GLP3(LY3437943), a novel triple-acting receptor agonist targeting the GIP, GLP-1, and glucagon receptors simultaneously. Each pen contains 30 mg/2.4 mL (4 doses of 7.5 mg). Reta-GLP3 is an investigational peptide currently being studied for its pharmacological properties and potential applications in metabolic disorders, NASH/MAFLD, and related metabolic conditions. Additional preclinical and clinical studies are required to further evaluate its safety, efficacy, and potential therapeutic applications. Not approved for clinical use. For research purposes only.

Cagrilintide20 mg

KLIKTIDE contains cagrilintide, a novel long-acting acylated amylin analogue designed for once-weekly subcutaneous administration. Each pen contains 10mg/2ml. Cagrilintide activates the amylin receptor (AMY1 and AMY3), which plays a key role in satiety signaling, gastric emptying, and post-prandial glucagon suppression. Research has demonstrated significant weight loss as monotherapy and synergistic effects when combined with GLP-1 agonists (CagriSema trials).

Tesamorelin20 mg

Tesamorelin is a synthetic growth hormone-releasing hormone (GHRH) analogue consisting of the 44-amino acid sequence of human GHRH with a trans-3-hexenoic acid group attached to the tyrosine residue. Each TESAKLIK pen contains 30mg/3ml. This modification increases resistance to enzymatic degradation. Research has focused on its effects on visceral adipose tissue reduction, particularly in the context of lipodystrophy and metabolic syndrome models.

Bacteriostatic Water10 ml

Store at 2–8°C, do not freeze.

For laboratory research use only. Not for human or veterinary administration.

Frequently asked questions

Orders are dispatched in insulated, temperature-controlled packaging with cold packs where required. Tracked delivery is £20 everywhere. Free delivery on orders of £300 or more. Tracked UK delivery typically arrives within 1–3 working days. If the packaging arrives damaged or warm, contact us within 24 hours and we will arrange a replacement batch.

Products with an inspected external report list the report ID, tested compound and amount, source laboratory, measured purity where reported, and a link to the external record. A report applies only to that tested sample and does not verify every variant or future batch.

Follow the product label, supplied documentation and your validated laboratory protocol. Storage requirements can vary by compound and presentation, so no single temperature or duration applies to the whole catalogue.

Use only the diluent, concentration, aseptic process and stability window defined by your validated protocol and the applicable product documentation. Apex does not publish one universal reconstitution instruction for every compound.

Because products are perishable and supplied for research use, they are non-returnable once dispatched, unless the cold chain has been broken or the batch is defective — in which case we will replace it. See our shipping and returns policy for full terms.

No. All products are supplied strictly for laboratory research use only, and must not be administered to humans or animals. Orders are screened accordingly.
