A straightforward protocol combining PT-141 for acute sexual function enhancement with Enclomiphene for sustained testosterone and libido support.

CompoundDoseFrequencyTimingRole
PT-141 (Bremelanotide)1.75mgAs needed, max 2x per week45-60 minutes before sexual activityAcute libido and arousal enhancement via melanocortin receptor activation
Enclomiphene12.5-25mgDaily (oral)Morning with or without foodSustained testosterone production support, LH/FSH stimulation, fertility preservation

Why This Stack Works

PT-141 and Enclomiphene address sexual health from two complementary angles. PT-141 (Bremelanotide) works centrally in the brain through melanocortin-4 receptors to directly enhance sexual desire and arousal — it is the only FDA-approved peptide for hypoactive sexual desire. Unlike PDE5 inhibitors (Viagra, Cialis), PT-141 targets desire rather than just blood flow.

Enclomiphene, the trans-isomer of Clomiphene, stimulates the pituitary to produce more LH and FSH, which in turn drives natural testosterone production. This provides the sustained hormonal foundation that supports libido, energy, and sexual function over time — without shutting down endogenous production the way exogenous testosterone does.

Who This Protocol Is For

  • Men experiencing low libido or reduced sexual desire
  • Men with borderline-low testosterone who want to avoid TRT
  • Men on TRT who want to preserve fertility (Enclomiphene maintains LH/FSH signaling)
  • Anyone seeking on-demand arousal enhancement without daily PDE5 inhibitor use

PT-141 Usage Guide

PT-141 is not a daily medication. Use it strategically:

  • Onset: Effects begin 45-60 minutes after injection and can last 12-24 hours
  • Frequency: No more than 2 times per week, with at least 24 hours between doses
  • Side effects: Nausea is the most common side effect (usually mild and transient). Flushing and mild headache may also occur
  • Tip: Start with 1mg for your first dose to assess tolerance, then increase to 1.75mg

Enclomiphene Daily Protocol

Enclomiphene provides the hormonal backbone of this stack:

  • Starting dose: 12.5mg daily
  • Adjustment: Increase to 25mg if bloodwork at 4 weeks shows insufficient testosterone response
  • Typical results: Total testosterone increases of 200-400 ng/dL within 4-8 weeks
  • Key advantage: Unlike TRT, Enclomiphene preserves (and may enhance) fertility by maintaining gonadotropin signaling

Expected Results Timeline

  • Week 1: PT-141 effects are immediate from first use (acute, per-dose benefit)
  • Weeks 2-4: Enclomiphene begins raising testosterone levels; gradual improvement in baseline libido and energy
  • Weeks 4-8: Full testosterone response from Enclomiphene; sustained improvement in sexual function, mood, and vitality
  • Ongoing: Maintain Enclomiphene daily; use PT-141 as needed for peak encounters

Bloodwork Markers to Monitor

  • Total testosterone and free testosterone
  • LH and FSH (should increase on Enclomiphene)
  • Estradiol (monitor for elevation)
  • SHBG
  • Liver enzymes (AST, ALT)
  • Complete blood count

Safety Notes

  • PT-141 can cause nausea, especially at higher doses. Take an anti-nausea medication (e.g., ondansetron) 30 minutes prior if needed.
  • Do not use PT-141 if you have uncontrolled hypertension or cardiovascular disease.
  • Enclomiphene may cause mild visual disturbances, headache, or mood changes in some users. These are uncommon at the doses used in this protocol.
  • Both compounds should be used under medical supervision with appropriate bloodwork monitoring.
  • Store reconstituted PT-141 in the refrigerator and use within 30 days.
