- Nirvana Biome.com – the newest kid on the block. They use CosmosId. Discount Code: prescript15 – 15% Discount. They report includes virii and fungii and candida, while more expensive — for troublesome conditions, it is good to have these additional areas covered. They have a special interest in Autism.
