Hi Sharlie, Thanks for the detailed specs—happy to price this using the same format/amount you order for your current Methamphetamine Plus control. We need some additional information to submit your request for a quote. If you could please complete the chart below, it will help with the submission of a quote. If you have any questions, please do not hesitate to contact us. Customer Design Details 1. Matrix (i.e. urine, serum, blood, etc.) Defibrinated plasma (please confirm) 2. Form (frozen: 18 month expiration / freeze dried: 30 month expiration) ☐ Frozen ☐ Freeze-dried (please select) 3. Fill Size (frozen: 0.25 mL – 1 gallon / freeze-dried: 3 – 10 mL) Same as your current Methamphetamine Plus order? (please specify vial size and pack configuration) 4. Quantity (how many vials of each product? Minimum order size is 50–60 mL per level) Same as current order? (please specify total vials / mL) 5. Analytes and Concentrations Current: • Amitriptyline – 800 ng/mL • d-Amphetamine – 800 ng/mL • d-Methamphetamine – 400 ng/mL • Diazepam – 1200 ng/mL • Meperidine – 400 ng/mL • Thioridazine – 4000 ng/mL Additions requested: • Butalbital – 2000 ng/mL • Carisoprodol – 2000 ng/mL • Phenytoin – 3000 ng/mL (Confirm these targets and note any changes.) 6. Shipping Address (company, attention, street, city, state, ZIP, phone) A couple quick notes based on your questions: • Expiration: Labelled shelf life is primarily driven by form (frozen ≈18 months; freeze-dried ≈30 months). Adding these three analytes typically does not extend expiry on its own; we’ll confirm final dating after formulation/stability review. • Evaluation sample: We can provide a small pilot/evaluation lot before shipping out the full product. Please indicate vial size and how many you’d like for testing. Please let us know if you have any questions, have a wonderful day! Thank you, Quinton Reed Business Development Rep.

Thanks for introducing yourself :) Our schedule's are pretty hard to get lined up, it's hard to take away time from the bench to be able to have conversations as we are often short staffed and working multiple benches. I do have some items in relation to your proposed agenda that we could maybe line up to dicuss. However, I do have a QC that I'd like to see a cost quote on: We currently order a Methamphetamine Plus in defibrinated plasma control that I would like to add some more analytes to and see how much that might cost. Currently the control contains: AMITRIPTYLINE - 800 ng/ml d-AMPHETAMINE - 800 ng/ml d-METHAMPHETAMINE - 400 ng/ml DIAZEPAM - 1200 ng/ml MEPERIDINE - 400 ng/ml THIORIDAZINE - 4000 ng/ml I would like to see what the cost difference would be if we added the following: BUTALBITAL - 2000 ng/ml CARISOPRODOL - 2000 ng/ml PHENYTOIN - 3000 ng/ml If you could do a mock price quote using the same way/amount we order for the methamphetamine plus control that'd be great. Additionally, would the addition of the 3 analytes change at all the master expiration date of the control? If it would make it longer, we would purchase more vials than what we normally do. Depending on the cost, most likely what we would do is ask you to make us a small batch/sample vial so we can test it with our assays to ensure there are no problems with recovery, and then we would order a larger volume. Thanks!
