Healthy cortisol levels for men who run on stress.
Cortisol and testosterone share the same hormonal axis. When one stays high, the other stays low. Not sometimes. Always. That's how your biology works.
Short-term stress is fine. Your body handles it. But the chronic kind—work pressure, poor sleep, overtraining, constant mental load—keeps cortisol elevated around the clock. And elevated cortisol suppresses testosterone directly.
Corti-Guard brings cortisol back to healthy levels so your testosterone can stay where it belongs.
The Formula
6 compounds. Clinical doses. 1 capsule a day.
- Ashwagandha KSM-66® — 300 mg – Gold-standard adaptogen clinically proven to lower cortisol by up to 27.9% while increasing testosterone
- Tongkat Ali Extract — 200 mg (1.5-2% eurycomanone) – Reduces cortisol while boosting testosterone production

Six-dimension breakdown
Why this scored 67/100
Fully disclosed doses: KSM-66 300mg (clinical dose from Chandrasekhar 2012), Tongkat Ali 200mg standardized to 1.5–2% eurycomanone (Talbott 2013), Rhodiola 200mg, PS 200mg, L-theanine 200mg, Mg bisglycinate 200mg. Formulation is coherent and honest about cortisol/testosterone axis. Loses on smaller-brand manufacturing evidence and no COA disclosure.
Evidence & sources
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.
How to read the Evidence dimension
- 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
- 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
- 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
- 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
- 0–19: No credible evidence base or unverifiable claims.
