Four product lines, one standard: transparency.

• Research peptides: third-party tested, sold strictly for laboratory research use.
• Mushroom & wellness supplements: functional mushrooms, energy & focus, daily wellness, performance and metabolism.
• Handmade natural soaps: small-batch, mushroom-infused bars.
• Merch that plants trees: all merch proceeds go to One Tree Planted.

Because we show our work.

• Peptides are third-party tested for identity and purity, with COAs available. Use See COA’s at the top of any page.
• Our Transparency Series sells lots that test short of target at a steep discount, with full disclosure, instead of hiding them.
• A 300% money-back guarantee on valid testing.
• A real person answers every message.
