Peptide Ingredients FAQ

Are these finished cosmetic products?

No. IngredientOS supplies professional raw cosmetic ingredients and peptide concentrates for formulators, labs, and brands to use when creating their own serums, creams, and treatment products. These are not ready-to-use consumer skincare products.

How do I choose a peptide?

Match the peptide to your formulation goal: expression-line smoothing (e.g. Argireline, SNAP-8), structural firming (e.g. Matrixyl), repair and renewal (e.g. Copper Tripeptide-1), or specialty actives such as PDRN. Review INCI, usage rate, and solubility on each product page before formulating.

What sizes are available?

Most liquid peptide concentrates are offered in sample-friendly sizes starting at 10 mL (0.33 oz), with larger options such as 1 oz, 4 oz, 8 oz, and bulk packs on individual product pages. Available packaging varies by SKU — select your pack size on the product page.

Where do orders ship from?

Orders ship from our Florida, USA warehouse. We currently fulfill professional ingredient orders within the United States.

When is US shipping free?

Free standard US shipping applies to orders of $50 or more before tax. Below that threshold, Florida addresses are $5.95 and other US states are $6.95 per order.
