Measurement protocols — all endpoints in one page

These are the objective endpoints that would actually test each compound's claims — as opposed to the subjective anecdotes the marketing relies on.

General design rules (apply to every compound)

Pre/post design: baseline draw → intervention period → repeat draw. Same lab, same assay, same time of day where diurnal variation exists (hormones, cortisol). Fasting where required.
Interval: 8–12 weeks for immune/metabolic panels; 12 months minimum for telomere-length claims (natural inter-assay drift exceeds any effect otherwise).
Self-reported feelings are not endpoints. "I slept better" is a hypothesis, never a result.
Retest cadence: repeat the exact same assay at the same lab; switching kits mid-n voids the comparison.
Cost expectation: telomere assays ~$260–400/draw; immune subsets ~$100–300; standard organ panels $30–80. Budget for the pair.

Per-compound endpoints

Epitalon (AEDG)

Telomere length pre/post — SpectraCell qPCR (~$259) or Life Length HT-Q-FISH (~$300–400). Triplicate samples, 12-month interval, fasting draw, same lab, same assay both draws. NOT "I sleep better."

Thymalin

CD3/CD4/CD8 T-cell subsets, NK cell activity, IL-2 level, TREC (thymic output) assay. 8–12 weeks pre/post, same lab. NOT "I feel healthier."

Vilon (KE)

IL-2 levels, macrophage activity, hepatic function panel. Pre/post at 8–12 weeks.

Cortexin

Cognitive testing battery (MoCA, Trail Making A/B), EEG changes, neuroinflammation markers (NfL). NOT "I think more clearly."

Pinealon (EDR)

Cognitive battery (Trail-making, Stroop, digit span), EEG, NfL neuroinflammation marker.

Prostamax (KEDP)

IPSS symptom score, PSA, prostate volume (ultrasound), urinary flow rate (Qmax). NOT subjective "feels better."

Cartalax (AED)

Joint MRI, COMP and CTX-II cartilage biomarkers, WOMAC score. Pain scale as secondary endpoint only.

Livagen (KED)

Liver panel (ALT/AST/GGT), lymphocyte subset analysis.

Vesugen (KED)

Endothelial function testing (flow-mediated dilation), vascular reactivity.

Chonluten (EDG)

Respiratory function (spirometry), TNF/inflammation markers.

Retinalamin

OCT monitoring, visual acuity, retinal nerve fiber layer thickness. Annual eye exams.

Thymogen (EW)

Same immune panel as Thymalin (CD3/CD4/CD8, NK activity, IL-2, TREC), 8–12 weeks pre/post.

Ovagen

Liver panel (ALT/AST/GGT), hepatic ultrasound.

Pancragen

HbA1c, C-peptide, insulin sensitivity (HOMA-IR).

Testagen

Total/free testosterone, LH, FSH, testicular ultrasound. Draw at same time of day, same lab.

Crystagen (EDP)

Immune markers (same panel as Thymalin: CD subsets, NK activity).

Cardiogen

Echo (ejection fraction), ECG, BNP, troponin, lipid panel.

Ventfort

Doppler flow, microcirculation assessment, BP monitoring.

Where to get the tests

Telomere length: SpectraCell Telomere Test (qPCR, ~$259) or Life Length HT-Q-FISH (~$300–400, more precise).
Immune panel: any major lab: CD3/CD4/CD8 flow cytometry, NK cell function, IL-2, TREC via specialty labs.
Organ panels: standard clinical chemistry (hepatic, renal, lipid) + compound-specific: PSA/IPSS (urology), HbA1c/C-peptide/HOMA-IR (pancreas), echo/BNP (cardiac), OCT/RNFL (retina).
Cognitive: MoCA, Trail Making A/B, Stroop, digit span — standardized, repeatable.
