Evidence Anchor
BioHarmony 6.6/10
Thymulin earns a Neutral score because it pairs unusually well-defined biology with an unusually thin human-treatment file. If you understand zinc status, want a chemically defined thymic hormone rather than an undefined extract, and accept that no modern human trial supports the injected peptide, it is a defensible research-grade experiment with a favorable intrinsic safety record and excellent reversibility. If you are chasing a proven clinical result, the data are not there, and for a documented zinc deficiency the cleaner move is to correct zinc, which has stronger human evidence than injecting thymulin. The two biggest real-world frictions are the two-directional pain effect, which makes dose direction matter, and grey-market sourcing, which adds purity and identity risk on top of the molecule's own profile. ✅ Best for: Zinc-aware self-experimenters who will check their zinc level before and during use, since zinc status gates how much active thymulin they have. Older adults and those with a documented zinc-driven immune deficit, who show the clearest restorable signal in the literature. People who specifically value a defined molecule with receptor-level science over an undefined extract. Researchers comparing thymic peptides who want the best-characterized mechanism in the group. Anyone who can source verified material with a certificate of analysis and will treat the whole thing as observation, not treatment. ❌ Avoid if: You have active or suspected cancer, because immune and neuroendocrine signaling is not something to experiment with in that setting. You are pregnant or breastfeeding, where there is no human safety data. You want to self-treat chronic pain by guessing a dose, since the low-dose direction can make pain worse rather than better. You are already zinc-replete and expect a strong effect, because the responder profile skews toward deficiency. You cannot verify source quality, because grey-market peptides carry purity, identity, and contamination risks that may exceed the molecule's own.

My score and my verdict: one signal of three, never the whole answer.
Momentum
Signals begin with Edition 2
Direction needs two weekly snapshots to compare, so the arrows stay off until the next edition. Attention tracking is already running.
Momentum = how fast attention is rising across search, Reddit, PubMed, podcasts, and curated industry newsletters this week; it can flag an item as Overhyped/Fading, but it never overrides the evidence behind Proven. How momentum works.

The score anchors the ring; the other five drive momentum, which can nudge the ring by one step at most. How placement works.
