Frequently Asked Questions

Peptides are short chains of amino acids — the fundamental building blocks of proteins.

They occur naturally throughout biological systems and are involved in a wide range of cellular signalling and biological processes. Synthetic peptides are produced for controlled scientific and laboratory research, allowing researchers to investigate specific biological pathways and mechanisms.

Our products are intended for researchers, scientists, laboratories and other qualified research professionals purchasing for legitimate research purposes.

Purchasers must meet our applicable age and purchasing requirements and agree to use the products exclusively for research.

Our peptide products are independently tested for purity, with many products achieving ≥99% purity by HPLC analysis.

Where applicable, small-molecule research compounds may have different validated purity specifications. The relevant purity information for each product is provided with its supporting documentation.

We believe research quality starts with transparency — which is why product-specific analytical information should always be available for review.

Yes. A Certificate of Analysis (CoA) can be provided for applicable batches.

The CoA contains relevant analytical information for the specific batch, helping researchers verify the product specifications and analytical results associated with their purchase.

For a CoA request, please contact our team with your order number and product name.

Our applicator products are supplied in a pre-filled format containing a prepared liquid formulation, where applicable.

There is no requirement for the customer to reconstitute a freeze-dried powder when purchasing a pre-filled product.

Product-specific concentration, formulation and handling information should always be checked on the relevant product documentation.

Storage requirements can vary according to the specific product.

Where the product documentation specifies refrigerated storage, keep the product at 2–8°C, protected from light, and do not freeze.

Always follow the storage instructions provided on the individual product page, product label and accompanying documentation.

For batch-specific information, refer to the relevant Certificate of Analysis or product documentation.

For products supplied as pre-filled applicators, no reconstitution or mixing is required.

Unlike freeze-dried research products that may require preparation before laboratory use, a pre-filled applicator is supplied with its formulation already prepared.

Always refer to the individual product documentation for correct laboratory handling procedures.

Our applicator products are designed to dispense a pre-measured quantity with each calibrated adjustment/click, according to the specifications of the individual product.

Because concentrations and product specifications can differ, please refer to the product-specific documentation and our Amount Calculator for measurement information relevant to laboratory research.

Important: Calculator results are provided as a measurement reference for research purposes only and should not be interpreted as medical, therapeutic or dosing advice.

Our Amount Calculator is designed to help researchers understand the relationship between a product's stated concentration and the calibrated amount associated with the applicator.

Simply:

1. Select your product
2. Enter the relevant amount
3. Review the corresponding calculated measurement

The calculator is provided strictly as a research measurement aid. It does not provide medical, therapeutic or human dosing instructions.

NAD⁺ (nicotinamide adenine dinucleotide) is a naturally occurring coenzyme found in every cell of the body. It plays a fundamental role in how cells produce energy, maintain metabolic function and respond to cellular stress.

It is essential for converting nutrients into cellular energy and supports enzymes involved in DNA repair, cellular signalling and maintaining cellular health.

NAD⁺ participates in pathways responsible for cellular energy metabolism, mitochondrial function, DNA maintenance and repair, cellular signalling, metabolic regulation and responses to cellular stress.

As we age, NAD⁺ metabolism can change, which has led to growing scientific interest in NAD⁺ and its role in healthy ageing and cellular resilience.

Each Core Biotech NAD+ pen contains 1000 mg of NAD+ in a total volume of 3 mL.

The pen holds 240 total units, with approximately 4.1666 mg of NAD+ per unit.

Option 1 — Twice Weekly: 30 units per dose = 125 mg NAD+ per dose, used twice a week.

Option 2 — Three Times Weekly: 20 units per dose = 83.3333 mg NAD+ per dose, used three times a week.

Always follow the product instructions provided with your kit.

Each unit contains approximately 4.1666 mg of NAD+, so 20 units ≈ 83.33 mg, 30 units = 125 mg and the full 240 units = 1000 mg.

Both recommended options use 60 units per week — either 2 × 30 units or 3 × 20 units. At 240 units per pen, that works out to approximately four weeks of use per pen.

Wash your hands and let the cartridge rest at room temperature for 3 minutes. Insert the cartridge into the holder, reattach it and twist on a new sterile needle. Hold the pen upright, dial one click to prime, tap the cartridge to move air bubbles to the top and press the button until a small drop appears — the pen is then ready.

Clean and pinch the chosen site, insert the needle at a 90° angle, set your dose and hold for 5 seconds. Withdraw the needle, apply gentle pressure with sterile gauze without massaging the site, and dispose of the needle in a sharps container.

The full illustrated 10-step guide is shown on the NAD+ product page.

The lower abdomen (at least 5 cm from the navel), the outer thigh (front or outer area) or the upper arm (back or outer area).

Clean the area with an alcohol swab and pinch a fold of skin of about 2–3 cm before use.

Yes. Follow the instructions supplied with your specific Core Biotech product, and seek advice from a qualified healthcare professional before using an injectable product.
