Pal-AHK
Also known as: Palmitoyl Tripeptide-1, Pal-GHK
Fatty acid-conjugated tripeptide with enhanced skin penetration for collagen stimulation and anti-aging effects. The palmitoyl group increases lipophilicity and transdermal bioavailability.
Beginner Basics
Plain-English guide to Pal-AHK
What it does
This is a small chain of amino acids (building blocks) attached to a fatty acid that helps it absorb into skin. Researchers use it to encourage skin cells to make more collagen, which is the protein that keeps skin firm and smooth.
Typical dose
Typical research products contain 2-5% concentration applied to skin once or twice daily, starting with once daily and gradually moving to twice daily if skin tolerates it well.
When to inject
This is applied topically to clean skin as part of a morning and/or evening skincare routine-no injection needed.
Storage
Store the dry powder in a cool, dry place away from light. Once mixed into a serum or cream, keep it in a cool environment and use within the manufacturer's recommended timeframe.
First-timer tip
Start with just one application per day for the first week or two to let your skin adjust, then increase to twice daily if there's no irritation.

Research Areas
Side Effects
May occur in sensitive individuals or with initial use. Usually resolves within 1-2 weeks of continued use as skin adapts. Reduce frequency to 1x daily if irritation persists.
Some users report a mild warming sensation during the first few applications. This typically subsides and is not a sign of adverse reaction.
May occur if applied to already-dry skin or if used in conjunction with other active ingredients. Ensure adequate moisturization and reduce application frequency if needed.
Possible in individuals with sensitivity to peptides or formulation excipients. Discontinue use and consult a dermatologist if rash, swelling, or severe itching develops.
No documented photosensitivity from Pal-AHK itself, but some topical formulations may contain photosensitizing excipients. Always use SPF 30+ sunscreen during daytime use.

Reconstitution Guide
Do not use saline or bacteriostatic saline, use only bacteriostatic water for reconstitution
Do not shake the vial vigorously; gentle swirling prevents peptide degradation
Discard immediately if the solution appears cloudy, discolored, or contains visible particles
Use within 30 days of reconstitution when stored at 2-8°C
Do not freeze the reconstituted solution; freezing may denature the peptide

Molecular and Pharmacological Data
| Molecular weight | 531.7 g/mol (palmitoyl-conjugated tripeptide) |
| Sequence | Members only |
Pal-AHK is a lipid-conjugated tripeptide that penetrates the stratum corneum and dermis to bind growth factor receptors and stimulate fibroblast proliferation and collagen I and III synthesis. The palmitoyl fatty acid moiety enhances transdermal penetration and cellular uptake, promoting dermal remodeling and anti-aging effects through increased extracellular matrix deposition.
