How we scored this product Show the full breakdown
Dose vs. studies (55%) Why 5.1 of 10. Primär ingredient is Spermidin (evidence grade B). It delivers 667% of the trialled dose. Above the studied range docks the score because nobody has tested that much. Read the rule → 5.1
Transparency (20%) Why 7.0 of 10. Earned points for public certificate of analysis and independent third-party testing and all doses disclosed. Read the rule → 7.0
Value (10%) Why 9.8 of 10. Pris per effective day could not be calculated, so value defaults to the middle of the catalog. Read the rule → 9.8
Community sentiment (10%) Why 6.0 of 10. No external reviews found, so community sentiment defaults to neutral. Community never counts as clinical evidence. Read the rule → 6.0
Formulation (5%) Why 5.0 of 10. No published absorption advantage or disadvantage on file. The default of 5 is not a criticism. Read the rule → 5.0

Bevisning gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Säkerhet caps applied after weighting.

This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.

In plain language

Why this scored this way

This GenuinePurity Liposomal Spermidin scores 6.0, making it below the site average. It delivers the full 8mg trial dose of Spermidin with grade B evidence (promising human data, not yet comprehensive). At $0.25/day it's priced well for what you get.

What drives the score up

  • Tested by independent lab (transparency 7.0).
  • Value score of 9.8 at $0.25/day.
  • Spermidin is dosed at the full research level with grade B evidence (promising human data, not yet comprehensive).

What drags it down

  • Spermidin (8mg is 667% of the 1.2mg trial dose) is well above the trial dose. More is not always better.
