Ferritin dropped during a long BPC cycle — coincidence?
12 posts
Pulled a random CBC mid-cycle. Ferritin went 142 -> 87 ng/mL over 10 weeks on BPC-157. Hgb/Hct unchanged. No heavy periods (male), no GI bleeding, not donating blood.
Iron panel otherwise fine. Training and diet unchanged.
Anyone else seen ferritin drop on long BPC courses?

Ferritin is an acute-phase reactant — it goes UP with inflammation and DOWN when inflammation resolves. If BPC is reducing your systemic inflammation, ferritin coming down from 142 to 87 might not be 'iron stores depleted', it might be 'inflammation-driven ferritin elevation has resolved'.
Pull iron, TIBC, transferrin saturation. If TSAT is fine and iron is fine, you're just seeing normalized ferritin.

^ this is exactly right. Also pull hs-CRP. If CRP dropped alongside ferritin, the 'inflammation resolution' hypothesis is basically confirmed.

TSAT was 34% (in range), serum iron 98. hs-CRP actually went 2.2 -> 1.1 over the same window. So this is exactly the story you're describing. Whoa.
