pure beta ecdysterone

You will see offers from 50% up to 98%. At 50%, it’s a crude extract with lots of inert plant matter—fine if you just want ‘spinach extract’ on the label. For muscle-building supplements, 90% is the floor; most brands use 95% because it dissolves better in ethanol and lets you claim a higher dosage per capsule without bulking up the pill. At 95% HPLC, the remaining 5% is moisture, small amounts of ecdysone, and trace lipids. We recommend 95% for capsules because it blends evenly in a V-mixer and flows well on automatic filling machines.

The molecule itself is natural, but whether your final product gets an organic logo depends on the certifying body and the extraction solvents used. Our default process uses food-grade ethanol, which is accepted under many organic schemes. If you need EU organic or USDA NOP, we can switch to certified organic raw herbs and adjust our paperwork chain—there will be a price premium, but it’s doable. Ask your certifier about permitted extraction aids before ordering; we have seen clients get stuck because the auditor didn’t like the synthetic anti-foaming agent used during concentration (we can run without it).

We use HPLC-UV with a C18 column, mobile phase acetonitrile-water, and detection at 248 nm. The reference standard is USP-grade beta-ecdysterone. Each batch comes with a COA showing retention time, peak area, and the final percentage calculated against the standard curve. For customers who want extra confidence, we also run a moisture content (Karl Fischer), heavy metals (ICP-MS), and microbiology panel on every 25 kg drum. The COA is shared before shipment so your incoming QC can match the data.

In original vacuum-sealed foil bags at room temperature (below 25°C), the powder is stable for 24 months from the date of manufacture. Once opened, transfer it to an airtight container with desiccant and keep it away from direct light. Humidity is the enemy—it will clump and slowly degrade. We recommend re-testing after 6 months if repackaged. For liquid formulations, store the solution in ethanol at 2–8°C and use within 30 days.

We own the whole chain—from planting Cyanotis arachnoidea in Hunan to the finished powder—so there is no middleman adding cost. The production line runs under GMP with HACCP, and our facility is FDA registered. Price-wise, we sit in the ‘budget’ range without cutting UV purity. Minimum order is one drum, but we give the same batch-level testing to a 25 kg trial as we do to a 1000 kg order. Most customers stay because the COA tells the truth and delivery happens within the window we promised.
