How to Use PTD-DBM
Complete guide to PTD-DBM dosing, administration, timing, and protocol recommendations.
Quick Overview
PTD-DBM is a synthetic peptide studied for hair regrowth. It pairs a cell-penetrating protein transduction domain with a Dishevelled-binding motif, letting it slip into cells and block CXXC5, a natural brake on the Wnt/beta-catenin pathway that hair follicles use to enter their growth phase. In mouse studies, releasing that brake (usually alongside topical valproic acid) restarted hair growth and even formed new follicles in wounded skin. The honest catch: the entire efficacy record is preclinical and comes mostly from one lab. There are no completed human trials, no regulatory approval, and no proof it works on people. For research use only.
Dosing Guidelines
Common Dose
Supplied as 1 mg or 5 mg vials. A 5 mg vial in about 1 mL of water approximates the ~6 mg/mL used in the mouse study
Frequency
Once daily to the scalp in most community-reported routines
Dose Range
No established dose
Note: There is no proven human dose. Community-reported routines in hair loss circles reconstitute the labeled mg with bacteriostatic water (a reconstitution calculator turns the vial's mg into a mg/mL strength), with once-daily administration to the scalp, paired with valproic acid (VPA), the component associated with most of the reported hair response. Many reported routines add microneedling or dermarolling once or twice weekly to aid absorption, and run one to three months. Some combine it with GHK-Cu or other hair peptides. All of this is anecdotal and unproven.
Administration Method
Topical (applied to skin) in published research; usually co-applied with valproic acid
Best Time to Take
Not established (topical in animal studies)
No human timing data. In animal studies it was applied topically to the skin, generally alongside valproic acid.
Protocol Duration
Applied over several weeks in animal studies
Possible Side Effects
Not everyone experiences these. Individual responses vary.
- •No human safety data exists
- •Local skin irritation is possible, largely from the valproic acid it is paired with
- •Theoretical cancer concern: sustained Wnt/beta-catenin activation is a known driver of some tumors, and long-term effects are unstudied
- •Unknown systemic absorption and long-term safety
- •Effects in humans are entirely unproven
