The NAD+ AT HOME Pen Refill Kit delivers a complete resupply of 1000mg pharmaceutical-grade NAD+ in two ready-to-load cartridges — designed exclusively for use with the NAD+ AT HOME refillable auto-injector pen.\u003c\/p\u003e\n\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eNicotinamide Adenine Dinucleotide (NAD+)\u003c\/strong\u003e is a vital coenzyme present in every living cell, responsible for driving energy metabolism, DNA repair, and cellular communication. As we age, NAD+ levels naturally decline — resulting in fatigue, slower recovery, inflammation, and visible signs of ageing. Replenishing NAD+ via subcutaneous injection bypasses the digestive tract entirely, achieving near 100% bioavailability and rapid cellular uptake.\u003c\/p\u003e\n\u003cp\u003eEach refill kit contains two 500mg cartridges (3ml each), pre-filled with sterile pharmaceutical-grade NAD+ solution. Together they deliver 1000mg per supply cycle — the same clinical dose as the full kit — in a convenient, ready-to-load format engineered for the NAD+ AT HOME auto-injector pen.\u003c\/p\u003e\n\u003cp\u003eAvailable in 1, 2 and 3 month supply options with progressive savings on longer commitments.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eNote: The auto-injector pen and travel case are not included.
