A muscle-preservation stack built on the SARM ostarine, for protecting lean mass during a deficit or recovery.
Ostarine (MK-2866) is the most-researched SARM and the one with the most human data, studied specifically for preserving lean mass in muscle-wasting and cutting contexts — which makes it the anchor for a lean-preservation goal.
BPC-157 is added as an optional recovery support for the joints and connective tissue that take a beating in a deficit. SARMs are not approved for human use and carry real suppression and liver considerations; the compound page is blunt about the gaps in long-term safety data.
