01Mechanism of Action

Parameter
Dermorphin
GHRP-6
Primary target
μ-opioid receptors (central and peripheral)Negri 1992Steel 2014
Ghrelin receptor (GHS-R1a)Bowers 1990
Pathway
μ-receptor activation → G-protein coupling → adenylyl cyclase inhibition → neuronal hyperpolarization
GHS-R1a → Gαq → Ca²⁺ → GH release; central appetite driveBowers 2002
Downstream effect
Potent analgesia, reduced nociceptive signaling, opioid-mediated CNS and peripheral effects
GH pulse + strong appetite stimulation; modest IGF-1 elevationBowers 2002
Feedback intact?
N/A — exogenous opioid agonist
Origin
Phyllomedusa sauvagei and P. bicolor frog skin — gene-encoded with natural D-amino acid incorporationAmiche 1998Mignogna 1992
Synthetic hexapeptide; first-generation GHRP from Bowers groupBowers 1990
Antibody development

04Side Effects & Safety

Parameter
Dermorphin
GHRP-6
Opioid effects
Respiratory depression, sedation, euphoria, tolerance, dependence risk
CNS effects
Analgesia (high-affinity sites), catalepsy (low-affinity sites)Negri 1992
Kambô ritual toxicity
Violent emesis, vasodilation, profound fluid shifts, hyponatremia, ADH dysregulation, brain death (case report)Tran 2025

Receptor selectivity caveat
Two μ-receptor subtypes — differential behavioral effects (analgesia vs. catalepsy)Negri 1992

05Administration Protocol

Parameter
Dermorphin
GHRP-6
1. Legal and ethical framework
Dermorphin is a controlled substance in many jurisdictions and is not approved for human use. Possession, synthesis, or distribution may be illegal. Use is restricted to licensed research settings under institutional review.
Add 2 mL bacteriostatic water to 5 mg vial → 2.5 mg/mL.
2. Animal research protocols
In rodent models, intracerebroventricular (ICV) or intrathecal injection is used at nanomolar to picomolar concentrations. Subcutaneous administration also documented. All protocols require IACUC approval.
SQ — abdomen. Rotate sites.
3. Analytical detection
High-throughput LC-MS/MS screens developed for anti-doping programs detect dermorphin and 17 related peptides in equine and human urine/plasma at limits as low as 5 pg/mL.Steel 2014
Pre-meal for appetite support; pre-sleep for GH alignment.
4. Kambô ritual (traditional use)
Application of Phyllomedusa bicolor skin secretions to superficial burns. Not recommended — associated with severe toxicity including violent emesis, hyponatremia, and documented case of brain death.Tran 2025
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
5. Needle
29–31G, 4–8 mm insulin syringe.
