PTD-DBM (PTD-DBM (Wnt Pathway Hair Peptide))
A cell-penetrating peptide researched for hair regeneration by activating the Wnt/beta-catenin pathway. It became popular in biohacker hair protocols after studies paired it with valproic acid to induce new follicle formation.
How it works
PTD-DBM disrupts the interaction between CXXC5 and Dishevelled, releasing a natural brake on the Wnt/beta-catenin signaling pathway. Enhanced Wnt signaling promotes hair follicle neogenesis and regeneration.
Key facts
- Molecular weight: ~ (short cell-penetrating peptide)
- Half-life: Topical (local action)
- Bioavailability: Topical (local delivery)
- Storage: Refrigerate reconstituted solution; keep lyophilized cool and dry.
Dosing overview
- Typical dose: Topical scalp application (research)
- Frequency: Daily
- Duration: Ongoing (research)
- Route: Topical
Protocol notes
- Applied topically to the scalp, often reconstituted in a suitable carrier solution.
- Frequently paired with valproic acid, which also activates Wnt signaling, in research protocols.
- Consistent daily use over months is used to assess follicle regeneration.
Reported benefits
- Activates Wnt/beta-catenin hair pathway
- Promotes follicle neogenesis (research)
- Synergy with valproic acid
- Non-hormonal hair mechanism
Possible side effects
- Scalp irritation (possible)
- Unknown long-term human safety
- No approved human products
Research
- PTD-DBM induces hair follicle neogenesis (2017): Topical PTD-DBM with valproic acid activated Wnt/beta-catenin signaling and induced new hair follicle formation in animal models.
Community reviews of PTD-DBM
- longevity_anna rated it 5/5 - Worth adding to the protocol: PTD-DBM has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
- stack_logic_lisa rated it 5/5 - Genuinely effective after 3 months: Been using PTD-DBM for about 3 months and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
- recon_math_ray rated it 4/5 - Noticed clear benefits within weeks: Added PTD-DBM to my protocol about 4 months ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
