A quick fit check
Is this right for my pet?
There is uncontrolled infection, severe pain, rapid spread, bleeding, or the owner is looking for a direct treatment claim. PET157 is not for emergency care.
Published programme notes are general product information, not instructions for an individual animal. Professional review decides whether any pathway or plan is appropriate.
Package options
Three strengths. One 2 mL pen format.
Choose the package strength during the request. We recommend the S, M or L pen size that corresponds to your canine, while final suitability remains subject to professional review and regional availability. Discount applies to the pen subtotal; shipping is added after review.
Formula identity: The exact peptide and salt combination is a proprietary PET157-held trade secret. Verified batch-specific documentation is released only when it exists and is appropriate for professional review.
Presentation: Reviewed orders are prepared in sealed, tamper-evident packaging with integrity checks, light-protective secondary packaging and temperature-aware dispatch planning where appropriate. Dispatch is from Switzerland.

Research, evidence and limitations
The boundary that matters
Skin, wound and coat research around GHK-Cu needs professional interpretation before any clinical decision.
A research rationale does not establish a clinical outcome or replace professional review.
