Question 1

What exactly is IGF-1 LR3?

Accepted Answer

IGF-1 LR3 is supplied as a defined chemical entity: molecular formula C400H625N111O115S9, average molecular weight 9117.6 g/mol, CAS registry number 946870-92-4. Those three values are what identify the material unambiguously — a supplier that cannot state them is not describing a characterised compound. Each batch is accompanied by a certificate of analysis carrying the same identifiers.

Question 2

How is the purity of IGF-1 LR3 verified?

Accepted Answer

Purity is determined by high-performance liquid chromatography, with identity confirmed by mass spectrometry. The stated figure for this item is 99.0%. Verification is per batch rather than per product line, which is why the lot number on the vial and the lot number on the certificate of analysis have to match — a certificate that is not batch-specific documents nothing about the vial in front of you.

Question 3

Is IGF-1 LR3 available from a pharmacy, and what is the pharmacy price?

Accepted Answer

It is not, and there is none. IGF-1 LR3 is not an authorised medicinal product in the EU, the UK or the US, so no pharmacy dispenses it and no pharmacy price exists for it. It is supplied here strictly as a laboratory reference material for in-vitro research, not for human or veterinary use, and no prescription is issued or implied.

Question 4

How should IGF-1 LR3 be stored?

Accepted Answer

Store as received: Refrigerate 2–8 °C. Lyophilised material is stable far longer than material in solution, so it is kept sealed and dry until it is prepared for laboratory work; the recommended diluent for this item is Acetic acid water (0.6 % AA). Protect from light and from repeated temperature cycling, and record the date the vial was opened.

Question 5

Do you ship IGF-1 LR3 within Europe?

Accepted Answer

Yes. Orders are dispatched from within Europe with tracked delivery and plain, unbranded outer packaging, which is what keeps transit times short for EU destinations. Material is labelled for laboratory research use. Delivery windows and destinations are listed on the shipping page.
