Frequently Asked Questions (FAQ)
What is the MOQ for an OEM project?
Custom formulation projects typically start at 100-500 kg of finished product depending on the dosage form, while standard formulas in your own label start from a 10-25 kg drum of the ingredient depending on the item. Samples for bench trials start at 0.5-1 kg.
Can you develop a formula from scratch?
Yes. Send your target concept - dosage form, serving size, active ingredients and market - and we return a formulation proposal with ingredient specifications, sensory notes and a costed bill of materials.
Which dosage forms can you produce?
Gummies, capsules, tablets, drink powders, sachets and sports-nutrition blends, with packaging options including bottles, jars, stick packs, pouches and cartons.
How long does an OEM project take?
Typically 5-10 working days for a formula proposal and samples, 2-4 weeks for sample approval and artwork, then 15-60 days for bulk production depending on quantity and specification.
Who owns the formula, and do you sign NDAs?
We sign NDAs before receiving your brief, and a custom formula developed for you is produced exclusively for your brand and never resold to other clients.
