Dutasteride vs Glutathione: side-by-side comparison

Ancillary

Avodart · Dut · Duta

A dual 5-alpha reductase inhibitor that blocks both Type I and Type II isoenzymes, reducing serum DHT by roughly 90-94% at steady state (FDA trial median; some sources cite up to ~98%), versus ~70% with finasteride. More potent than finasteride for hair loss prevention but with a very long half-life of ~5 weeks. Clinically superior to finasteride for hair count and growth in head-to-head trials. Same caveats apply: only works with testosterone-based compounds, not DHT derivatives, and worsens nandrolone-related hair loss.

Health

Run for

Superior Hair Loss PreventionA 917-man phase III trial (Gubelin Harcha et al., 2014, J Am Acad Dermatol) found dutasteride 0.5mg significantly superior to finasteride 1mg for hair count (P=.003), hair width (P=.004), and investigator photographic assessment (P=.002).
Maximum DHT SuppressionReduces serum DHT by roughly 90-94% (FDA trial median; up to ~98% in some sources) vs finasteride's ~70%. For those who need maximum DHT suppression.
Prostate ProtectionReduces prostatic DHT by 97-99%. FDA-approved for BPH.
Less Frequent Dosing OptionDue to 5-week half-life, twice or thrice weekly dosing is effective and may reduce side effect frequency.

Documented upside

  • Reduces serum DHT by roughly 90-94% (FDA trial median; up to ~98% in some sources), vs ~70% with finasteride
  • Inhibits both Type I and Type II 5-alpha reductase
  • Commonly cited as ~3x more potent than finasteride at Type II inhibition, ~100x at Type I
  • Clinically superior hair count results vs finasteride in a 917-man phase III trial (P=.003)
  • Can be dosed 2-3x weekly due to long half-life

Dutasteride

Does not affect HPT axis directly. No PCT required. Very long half-life means effects persist months after stopping.

Glutathione

Not hormonal. No PCT required.

Read-out

How they separate

  1. 01

    Enhancement

    They land at almost the same point on the natty scale (1/10 vs 1/10): a similar distance beyond natural.

  2. 02

    Side-effect bill

    Dutasteride's documented side-effect severity is heavier (2.5/5 vs 2/5). The body-load fingerprint above shows where that weight actually lands.

  3. 03

    Body load

    The widest gap at typical protocols is shutdown depth (Dutasteride 3.2/10 vs 0/10), then mood & sleep (Dutasteride 3.2/10 vs 0/10).

  4. 04

    Coming off

    Neither requires PCT: both leave the natural testosterone axis running.

  5. 05

    Logistics

    Dutasteride runs as oral, Glutathione as intravenous; typical runs are 24-52 weeks vs 5-15 weeks.
