01Mechanism of Action

Parameter

Cerebrolysin

Tesofensine

Primary target

Multiple neurotrophic pathways — mimics BDNF, NGF, CNTF receptor activation

Serotonin / norepinephrine / dopamine transporters (SERT / NET / DAT)Astrup 2008

Pathway

Cerebrolysin peptides → BDNF/NGF/CNTF receptor binding → TrkB/TrkA/LIFR signaling → neuroprotection, neuroplasticity, synaptogenesis

Triple monoamine reuptake inhibition → ↑synaptic 5-HT, NE, DA → appetite suppression + thermogenesisAstrup 2008

Downstream effect

Reduced apoptosis (Bax ↓, Bcl-2 ↑), suppressed TNF-α inflammation, elevated endogenous BDNF, enhanced synaptic plasticity and motor recovery

Strong appetite suppression, mild thermogenic effect, weight lossAstrup 2008

Feedback intact?

Yes — exogenous peptides do not suppress endogenous neurotrophic factor synthesis

—

Origin

Enzymatic breakdown of lipid-free porcine brain proteins → standardized low-MW peptide fraction (<10 kDa) + free amino acids

Small molecule developed by NeuroSearch (Denmark) for CNS indications, repurposed for obesityAstrup 2008

Antibody development

Not reported in human trials; porcine origin theoretically immunogenic but no clinically significant allergic reactions documented

05Administration Protocol

Parameter

Cerebrolysin

Tesofensine

1. Preparation (IV infusion)

Dilute prescribed dose (10-50 mL) in 100-250 mL 0.9% sodium chloride. Use immediately after preparation. Do not mix with other medications in same infusion bag.

Oral capsule (investigational; not commercial).

2. Infusion rate

Administer over 30-60 minutes. Slower infusion reduces risk of transient hypotension or flushing. Monitor vital signs during first administration.

Swallow whole with water, morning only.

3. IM injection (alternative)

For 5-10 mL doses: inject deep IM into gluteal or deltoid muscle. Rotate sites if repeated daily. IM preferred for outpatient/chronic use.

Morning to mitigate insomnia. Do not dose evening.

4. Timing

Acute stroke: initiate within 6-12 hrs of symptom onset. Daily administration, preferably same time each day. Continue 10-21 days per protocol.

Room temp ≤25 °C, dry place.

5. Storage

Store unopened ampoules at 15-25°C, protected from light. Do not freeze. Use diluted solution immediately; discard unused portion.

Monitor BP + HR + mood. Avoid stimulants + MAOIs.

6. Co-administration

Compatible with standard stroke care (thrombolysis, thrombectomy, antiplatelet/anticoagulant therapy). Does not interfere with reperfusion therapies.

06Stack Synergy

Cerebrolysin

+ Semax

Moderate

View Semax →

Cerebrolysin (multimodal neurotrophic peptide mix) and Semax (ACTH(4-10) analogue) operate through complementary neuroprotective pathways. Cerebrolysin elevates BDNF and suppresses apoptosis/inflammation via TrkB/TrkA signaling, while Semax enhances neuroplasticity through BDNF upregulation and dopaminergic modulation. Combined use in stroke or TBI may amplify anti-apoptotic effects and accelerate cognitive/motor recovery, though no direct RCT data exist for the combination.

Cerebrolysin: 30 mL IV daily × 10-14 days
Semax: 300-600 mcg intranasal BID × 10-14 days
Timing: Concurrent during acute recovery phase
Primary benefit: Enhanced neuroprotection, accelerated motor/cognitive recovery post-stroke or TBI

+ BPC-157

Multi-pathway

View BPC-157 →

Cerebrolysin provides CNS-specific neurotrophic support (BDNF, NGF pathways), while BPC-157 offers systemic tissue repair via angiogenesis (VEGF upregulation) and anti-inflammatory effects. In traumatic brain injury or stroke, Cerebrolysin addresses neuronal survival and synaptic plasticity, whereas BPC-157 may enhance vascular repair and blood-brain barrier integrity. The combination targets both neuronal and vascular compartments of brain injury, though clinical validation is lacking.

Cerebrolysin: 30-50 mL IV daily × 14 days
BPC-157: 250-500 mcg SQ daily × 14-28 days
Timing: Initiate both within 24-48 hrs of injury
Primary benefit: Dual neuronal + vascular repair in TBI or stroke; accelerated functional recovery
