Dosing
How much do I take?
Topical: Applied onto the skin as a cream, gel, or lotion — it works mainly where you put it.
Bioavailability Local — acts mainly at the skin; little reaches the bloodstream.
2 documented dose levels — separate regimens, not a titration schedule
Under 10 ppm (<0.001%) in finished product
Frequency
Once or twice daily
Duration
Ongoing
~3% trade solution (Matrixyl 3000 blend)
Frequency
Twice daily
Duration
~2 months
In manufacturer clinical testing the trade-solution blend was applied twice daily for about two months [6]. The ~3% figure refers to the diluted trade solution, which contains only ppm-level active peptide.
Timing
Best time to take
Apply Palmitoyl Tetrapeptide-7 to clean, dry skin. For best results, use consistently at the same time(s) each day. Evening application is often preferred to allow overnight absorption, unless otherwise directed.
With food?
As a topical product, Palmitoyl Tetrapeptide-7 is not affected by food intake. Apply to clean skin and allow adequate absorption time before covering the area.
If stacking
Palmitoyl Tetrapeptide-7 should be used as directed by your healthcare provider. If combining with other medications or supplements, discuss potential interactions with your provider. Avoid combining with compounds that have overlapping mechanisms unless specifically guided by a medical professional.
Adjusting your dose
Increase if
- You've tolerated the current dose for the recommended period without significant side effects
- Therapeutic goals haven't been met at the current dose level
- Your healthcare provider recommends dose escalation based on your response
- Lab work or clinical assessments support a higher dose
Decrease if
- Side effects are bothersome or impacting daily life despite management strategies
- You experience any signs of an adverse reaction
- Lab results indicate the need for dose reduction
- Your healthcare provider recommends a lower dose based on your response
Signs of right dose
- Therapeutic goals being met with minimal side effects
- Stable and consistent response to treatment
- Lab values or clinical markers trending in the right direction
- Good tolerance with manageable or absent side effects

Storage
Before reconstitution
Store Palmitoyl Tetrapeptide-7 in the refrigerator at 36-46°F (2-8°C) in its original packaging. Protect from light and moisture. Do not freeze. Check the expiration date before use. Some formulations may be stored at room temperature for limited periods—check your specific product labeling.
After reconstitution
Once reconstituted, Palmitoyl Tetrapeptide-7 should be kept refrigerated at 36-46°F (2-8°C) and used within the timeframe specified on your product labeling (typically 14-28 days). Label the vial with the reconstitution date. Do not use if the solution appears cloudy, discolored, or contains particles.
Signs of degradation — discard the vial
