Soy Peptone

Soy peptone is a premium protein source that is widely used in mushroom cultivation to enhance mycelium growth and vitality. Packed with essential nutrients, it provides an excellent foundation for mycelial expansion, culture maintenance, and liquid culture preparation.

Derived from non-GMO soybeans, our specially selected, high-quality peptone delivers a rich profile of amino acids and peptides, supporting robust mycelial health and consistent performance. It’s the same grade we use in our own lab to cultivate strong, contamination-resistant cultures.

– Supplies vital proteins and amino acids for vigorous mycelial development.

– Ideal for liquid cultures, agar media, and substrate supplementation.

– Used by our team to produce high-yield, reliable mushroom strains.

Simply mix it into your media or nutrient solution for a proven boost to your cultivation process.

Orders are typically dispatched on the same or next working day. However, please allow up to 3 working days for dispatch, plus any additional product lead times, especially during busy periods.

We ship our products in plain, unbranded, reinforced cardboard boxes with ample internal protection.

Our shipping couriers may leave parcels with a neighbor or in a safe place if no one is home to receive them. To prevent this, please select the designated signed-for service at checkout and ensure you are available to receive the parcel. Otherwise, the package will be held at your local sorting office or returned to us. Please note that we cannot be held responsible for lost, stolen, or missing parcels if the signed-for service is not chosen at checkout.

Larger orders that require multiple boxes will automatically be upgraded to DPD Local shipping, as they support multi-parcel shipments. Extremely large or heavy orders may need to be dispatched via a pallet.

If items are returned to us due to a failed delivery, a redispatch or restocking fee may apply. Please ensure that any held packages are collected from your local sorting office within 2 weeks to avoid them being returned.

We highly recommend upgrading to the ‘DPD Express Tracked’ service at checkout, as we find it to be the fastest, safest, and most reliable option. Please note that Royal Mail may occasionally experience delays in their sorting offices.
