Quality & testing

Sealed lyophilized peptide powder under inert atmosphere. No fillers, no flow agents, no excipients beyond the standard lyo cake matrix. Each batch is independently lab-tested for purity (HPLC), identity (mass spec), heavy metals, and microbial load. Batch-matched Certificates of Analysis are available on request to verified buyers, email [email protected] with your order number.

Storage & handling

Lyophilized vials are stable at room temperature in the original packaging. Once reconstituted, store refrigerated (2–8°C) and use within the compound's stability window. The Dosage Calculator notes per-compound stability.

— Why this compound

A long-arg3 IGF-1 analog. The stabilised splice that extended IGF-1 plasma persistence from minutes to hours.

— How it works

Mechanism & pathways

IGF-1 LR3 (Long Arg3 IGF-1) is an 83-amino-acid analog of native IGF-1 carrying a 13-residue N-terminal extension and an Arg3 substitution. The modifications confer two effects research has measured: reduced affinity for IGF binding proteins (IGFBPs) and an extended plasma half-life relative to native IGF-1.

Less binding-protein sequestration means more free molecule available for IGF-1 receptor activation; the extended half-life shifts the molecule from a research tool requiring local administration into one that can support systemic research-protocol patterns. The literature describes both anabolic-pathway and metabolic-signalling research interest, with the primary use case in muscle-research, tissue-recovery, and IGF-axis modelling.

What the literature looks at

Research-framed mechanisms studied for this compound. Citations below describe published work; they do not represent product claims.

IGF-1 receptor activation

High-affinity binding at IGF-1R drives the same anabolic-pathway signalling as native IGF-1 with greater free-fraction availability.

Extended half-life

Plasma persistence in research models is documented at 20-30 hours versus minutes for native IGF-1 u2014 supports systemic-protocol research patterns.

Reduced IGFBP binding

The Arg3 substitution lowers affinity for IGF binding proteins, leaving more molecule available for receptor activation in research data.

Muscle-research models

Animal studies have measured satellite cell activation, myofiber growth, and protein-synthesis markers in mechanical-load research.

Reconstitution & protocol

  1. 01

    Reconstitute

    Add bacteriostatic water to the lyophilized vial along the wall, never directly onto the cake. Swirl gently, do not shake. Powder should fully dissolve into a clear solution.

  2. 02

    Store

    Refrigerate (2–8 °C) immediately after reconstitution. Keep upright in the original packaging away from light. Lyophilized vials stay stable at room temperature in their original sealed packaging.

  3. 03

    Protocol window

    Use within the compound stability window noted on the COA. Protocols vary by compound, see the Dosage Calculator for per-compound timing and the Ingredient Library entry for research-grade reference ranges.

  4. 04

    Stability

    Reconstituted shelf life is compound-specific. Discard the vial if the solution shows visible cloudiness, particulates, or color change. The Calculator notes per-compound stability windows.

— Frequently asked

Questions, answered.

Are your products safe?

Every batch is independently tested for purity, identity, heavy metals, and microbial contamination before it ships. Formulations use clinical-evidence doses, not under-doses dressed up as a "complex". For any specific medical concern, please consult a qualified healthcare professional.

How fast does delivery arrive in the UAE?

Most UAE orders arrive within 1–3 business days. Cold-chain dispatched, discreet packaging. Cash on Delivery is available across the UAE if you'd rather not share card details online.

Do you ship internationally?

Yes, where lawful. GCC countries typically arrive in 3–5 business days; further international destinations in 7–21 days depending on customs. Buyers are responsible for confirming legality of import in their jurisdiction.

Is the checkout secure?

Yes. The site uses bank-level encryption end to end. Payments run through Ziina (UAE-licensed) and Tabby (regulated BNPL); we never see card data on our servers. Cash on Delivery is also available across the UAE.

Will my order arrive discreetly?

Yes. Outer packaging is unmarked, with no NuroCore branding, no compound names, and no health-product references. Just a plain shipping carton. Your privacy is part of the product.
