Finasteride vs Glutathione: side-by-side comparison

Ancillary

Propecia · Proscar · Fin

A 5-alpha reductase inhibitor that blocks the conversion of testosterone to DHT, reducing serum DHT by 65-70%. Used during testosterone cycles to prevent DHT-related hair loss. CRITICAL: Only works with testosterone-based compounds. Does NOT work with DHT derivatives (Masteron, Winstrol, Anavar). Makes hair loss WORSE with nandrolone compounds.

Run for

Hair Loss Prevention During Testosterone CyclesBlocks conversion of testosterone to DHT, preventing DHT-mediated hair follicle miniaturization. Only effective with testosterone-based compounds.
Prostate ProtectionReduces prostatic DHT by 80-90%. PCPT trial showed 25% reduction in prostate cancer risk. Prevents testosterone-induced prostate enlargement.
Preserving Testosterone LevelsBy blocking DHT conversion, may increase circulating testosterone by ~15%, remaining within the normal physiologic range.

Documented upside

  • Reduces serum DHT by 65-70%
  • FDA Propecia 5-year trials: 90% of men had no further hair loss (48% regrowth, 42% no change)
  • May increase circulating testosterone by ~15% (still within physiologic range)
  • Does NOT impair muscle gains from testosterone (12-month RCT confirmed)
  • 25% reduction in prostate cancer risk (PCPT trial)

Support role

Finasteride

Does not affect HPT axis directly. No PCT required. Can be used long-term. May slightly increase testosterone by blocking DHT conversion.

Glutathione

Not hormonal. No PCT required.

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

    Finasteride'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 mood & sleep (Finasteride 3.2/10 vs 0/10), then liver strain (Glutathione 2.1/10 vs 0/10).

  4. 04

    Coming off

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

  5. 05

    Logistics

    Finasteride runs as oral, Glutathione as intravenous; typical runs are 12-52 weeks vs 5-15 weeks.
