Combination steroid-precursor product stacking DHEA with pregnenolone. DHEA has some RCT signal for adrenal insufficiency and low-DHEA populations (Panjari 2007 for postmenopausal women), while pregnenolone RCTs are mostly null. Stacking two hormone precursors compounds the safety complexity — both can shift the entire steroid hormone axis and should be lab-monitored, especially in men (aromatization to estradiol) and hormone-sensitive-cancer patients. Standard Swanson manufacturing. Would move to Verified 70+ with mandatory lab-monitoring language, contraindications, and per-active dosing disclosure — but the combination itself remains a formulation choice we can't fully endorse for self-administration.
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.

Strongest: Transparency at 62/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Formulation at 60/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Evidence at 50/100 (quality of published RCT support for the active ingredients at the label dose) and Safety at 50/100 (adverse-event profile, interaction risk, and dose ceiling). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
