    Frequently Asked Questions (FAQs)
    Q1: What documentation do you provide to verify product quality?
    A1: We provide a full Certificate of Analysis (CoA) for all products. For peptides, this includes HPLC purity chromatograms and Mass Spectrometry (MS) reports. For compounds like Botulinum Toxin or Cerebrolysin, we provide manufacturer-specific potency and quality control data. This ensures you receive precisely what you order.

    Q2: How are the peptides and blends formulated and shipped?
    A2: Peptides are typically supplied as sterile, lyophilized (freeze-dried) powders in sealed vials for maximum stability. Our proprietary blends (e.g., GLOW series) are precisely weighed and mixed under controlled conditions. All sensitive items are shipped with cold packs in insulated containers to maintain integrity.

    Q3: What is the typical lead time and minimum order quantity (MOQ)?
    A3: For standard in-stock items, lead time is 3-7 business days after order confirmation. MOQ varies by product but starts as low as 10 vial for many research peptides. We offer significant discounts for bulk and recurring commercial orders. Contact us directly for a specific quote.

    Q4: Can you create custom peptide blends or provide specific analogs?
    A4: Yes. Custom synthesis and blending are a core part of our service. We can develop tailored peptide combinations, specific concentrations, or modified analogs to meet your unique research or product development needs. Submit your specifications for a prompt consultation and quote.

    ECHEMI Editorial Reference
    Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence ("arginine 3"), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) ("long"), for a total of 83 amino acids (relative to the 70 of IGF-1).
