01Mechanism of Action

Parameter
Adamax
MGF
Primary target
Melanocortin receptors (MC-Rs) in hippocampus and cortex
Satellite cells (Pax7+) in skeletal muscleMoore 2018
Pathway
ACTH(4-10) fragment → MC-R binding → BDNF/trkB upregulation → neurotrophic signaling
Mechanical stress → IGF-1Ec mRNA upregulation → Local E-domain peptide release → Satellite cell activation
Downstream effect
Increased hippocampal BDNF expression, trkB tyrosine phosphorylation, enhanced conditioned avoidance learning, circadian rhythm normalizationDolotov 2006Arushanian 2008
Satellite cell proliferation, myoblast differentiation, muscle fiber repair

Non-endocrine — devoid of adrenal axis effectsvan 1978
Origin

MGF
Animal dose (rat)
50 mcg/kg body weightDolotov 2006
Single intranasal application; produced maximal BDNF response.

04Side Effects & Safety

Parameter
Adamax
MGF
Cardiovascular effects
ACTH(4-10) fragments may have pressor and cardioaccelerator actions at high dosesGruber 1984
Effects attenuated by α/β-receptor antagonists; observed at 30–1000 nmol/kg IV in rats.
Natriuretic effect
ACTH(4-10) exhibited natriuretic activity at lower doses (7 nmol/kg)Gruber 1984
Behavioral suppression
Suppression of aggression, reduced orientation-cognition reactions in rabbitsTeter 2001
May reflect anxiolytic or stress-dampening profile.
Long-term safety
Unknown — chronic human safety data lacking
Human safety data
None — no clinical trials published
Theoretical IGF-1 axis risk
Chronic IGF-1Ec overexpression linked to cancer progression (prostate, colorectal, breast)
Tumor promotion
IGF-1Ec overexpressed in osteosarcoma, colorectal polyps with dysplasia, endometrial cancer
Antibody development
Unknown — no longitudinal human exposure data
Local injection reaction
Presumed similar to other peptides (erythema, induration) — no direct evidence
Dysregulated expression with age
Older adults (70+ yrs) show blunted IGF-1Ec response post-exercise vs youngMoore 2018
Absolute Contraindications
Adamax
  • ·Pregnancy and lactation (precautionary; no data)
  • ·Active cardiovascular instability (due to potential pressor effects)
MGF
  • ·Active malignancy or history of IGF-1-sensitive cancers (prostate, colorectal, breast, osteosarcoma)
  • ·No established therapeutic use — investigational only
Relative Contraindications
Adamax
  • ·Hypertension (monitor BP if using higher doses)
  • ·Renal impairment (natriuretic effects may alter electrolyte balance)
MGF
  • ·Family history of IGF-1-axis malignancies
  • ·Use outside research setting

05Administration Protocol

Parameter
Adamax
MGF
1. Reconstitution (if lyophilised)
Add sterile water or bacteriostatic water to lyophilised vial per manufacturer guidance. Roll gently — do not shake. Ensure clarity before use.
MGF (E-domain peptide) has no approved clinical protocol. All published data derive from animal models or in vitro experiments.
2. Route
Intranasal administration is the primary route in animal and exploratory human studies. Delivered via nasal spray or dropper to ensure mucosal absorption.Dolotov 2006Smolnik 2000
Commercially available MGF corresponds to the 24-amino-acid human E-domain (hEc). Rodent E-domain (Eb) is structurally distinct and not interchangeable.
3. Timing
Variable. Single-dose protocols for acute cognitive tasks; chronic daily dosing for circadian rhythm normalization and sustained neuroprotection.
Rodent studies used peptide-eluting polymeric microstructures (cardiac) or direct intramuscular injection. Routes and doses non-translatable to humans.Peña 2015Shioura 2014
4. Storage
Lyophilised: room temperature, light-protected. Reconstituted: refrigerate 2–8 °C, use within manufacturer-specified timeframe.
MGF peptides prohibited in sport since 2005. Detection via LC-MS established for full-length MGF products.Thevis 2014
5. Research context only
Any human use falls outside approved medical practice and regulatory frameworks. No safety or efficacy data exist.

06Stack Synergy

Adamax
+ Semax
Moderate
View Semax

Both Adamax and Semax are ACTH(4-10)-derived nootropics acting via melanocortin receptors and BDNF upregulation. Adamax has distinct amino acid modifications at positions 8-10, potentially offering complementary receptor binding profiles or metabolic stability. Stacking may amplify neurotrophic signaling and cognitive enhancement, though direct synergy studies are absent. Theoretical multi-pathway benefit.

Primary benefit

MGF
+ BPC-157
Multi-pathway
View BPC-157

MGF activates satellite cells for muscle fiber repair; BPC-157 promotes angiogenesis, collagen synthesis, and tendon healing via distinct pathways (VEGF, FAK, integrin signaling). Theoretical synergy in post-injury contexts combines myogenic (MGF) and stromal (BPC-157) repair mechanisms. Both lack human validation.
