Membership
Every tier draws on the same research corpus and the same Reserve standard. What changes is depth of documentation, allocation, and the nature of your relationship with the house.

Read-only access to the Sakura Research Archive and the Journal of Applied Peptide Research.
Research Plus
Billed annually. Cancel anytime.
For active researchers who want earlier visibility into batches and deeper documentation.
Sakura Foundation
Foundation entry into the member Reserve.
Structured archive access, 1 monthly Research Allocation, and entry-level batch documentation.
Sakura Elite

Full Reserve access, generous monthly allocations, full batch documentation, and participation in the Sakura research ecosystem.
Wellness Concierge
On-demand enrollment. Private Concierge remains invite-only.
Structured, documented relationship with the house — priority Reserve, a private dossier, and a dedicated point of contact.

A small number of Concierge members are invited each year into Private Concierge — the most documented, most discreet tier the house offers.
