Is LIB-01 available for purchase?

No. LIB-01 is an investigational compound developed by Dicot Pharma currently in Phase 2 clinical trials for erectile dysfunction. It is not available through any pharmacy, peptide vendor, or supplement retailer. It is a plant-derived small molecule, not a synthesizable peptide.

How does LIB-01 differ from PT-141 (bremelanotide)?

Both LIB-01 and PT-141 act through melanocortin-4 receptor (MC4R) pathways, but they work differently. PT-141 is a direct MC4R agonist peptide administered by injection, while LIB-01 is an oral small molecule that modulates MC4R expression and its endogenous agonist levels. LIB-01 is notable for its long duration of action, with a 3-day oral course producing effects lasting 4-8 weeks.

Why is there community interest in LIB-01?

Community interest in LIB-01 stems from its unique properties compared to existing ED treatments. An oral compound that provides weeks of sustained effect from a short dosing course would be fundamentally different from daily PDE5 inhibitors or on-demand PT-141 injections. The Phase 2a results showing 8.5-point IIEF-EF improvement and 31% complete responders have generated anticipation.

Community Evidence Overview#

This page documents the community evidence landscape for LIB-01 (Libiguin). This is not clinical evidence and should not be used as medical guidance.

LIB-01 has no community self-experimenter data. It is an investigational small molecule in Phase 2 clinical trials that is not available outside of controlled research settings.

Why There Is No Community Data#

Pre-Market Investigational Status#

LIB-01 is in Phase 2 clinical development by Dicot Pharma. The compound is derived from phragmalin limonoids isolated from the Madagascan plant Neobeguea mahafalensis, making it a natural product-derived small molecule that cannot be easily synthesized by peptide vendors.

Not a Peptide#

Despite being profiled on this site for its relevance to the melanocortin receptor landscape and erectile dysfunction treatment, LIB-01 is a small molecule (molecular weight 699 Da) derived from plant compounds. It is not a peptide and would not be available through peptide synthesis suppliers.

Community Anticipation#

While there is no user experience data, LIB-01 has generated notable interest in erectile dysfunction and men's health communities for several reasons:

Oral administration eliminates the injection requirement of PT-141
Weeks-long duration from a 3-day course is unlike any existing ED treatment
Central mechanism through MC4R may address desire and arousal, not just erection mechanics
Phase 2a efficacy with 31% complete responders vs 0% placebo is promising

Comparison to Existing Options#

Community discussions about LIB-01 often compare it to:

PDE5 inhibitors (sildenafil, tadalafil) - on-demand or daily mechanical approach
PT-141 (bremelanotide) - injectable MC4R agonist with shorter duration
Melanotan-2 - non-selective melanocortin agonist used off-label for sexual function
