How many vials are in a IGF-1 LR3 kit?

Every kit is 10 vials. The "5mg" label means 5 mg per vial, so a 5 mg kit gives 50 mg total, a 10 mg kit gives 100 mg total, and so on.

Is the price per vial or per kit?

Prices shown are for the full 10-vial kit. We always show the per-vial and per-mg breakdown so you can compare honestly.

What payment methods do you accept?

SEPA bank transfer (IBAN) is our default — secure, fee-free, instant confirmation. We can also send a secure card-payment link on request via WhatsApp.

Do you ship outside the EU?

Yes — UK, USA, Middle East, Asia and Australia. EU is fastest (5–18 business days). International is tracked and discreet. Some destinations are restricted — checkout will tell you.

How is purity verified?

Every batch is independently tested by HPLC and mass spectrometry. We can send the batch-specific COA for your order on request.

Is this intended for human use?

No. IGF-1 LR3 sold by Regena Peptides is a research compound supplied strictly for in-vitro laboratory investigation by qualified professionals. Not for human or veterinary use.

What is IGF-1 LR3?

IGF-1 LR3 is a long-arginine-3 analogue of IGF-1 with reduced affinity for IGF binding proteins, extending the free-fraction half-life in anabolic and myogenesis research.

Mechanism of action

Reduced binding to IGFBPs prolongs free fraction.

Primary research areas

Anabolic signaling and myogenesis studies.

Research notes

Reduced IGFBP binding distinguishes it from native IGF-1 in assays.
