Tesofensine- Summary
- Syn-Ake is a synthetic tripeptide that mimics waglerin-1, a peptide found in the venom of the Temple viper (Tropidolaemus wagleri). It acts as a reversible antagonist of muscular nicotinic acetylcholine receptors, temporarily reducing facial muscle contraction and smoothing dynamic wrinkles. Often called a 'synthetic Botox' in cosmetic marketing.
- Tesofensine is a triple monoamine reuptake inhibitor (TMRI) that blocks reuptake of serotonin, dopamine, and norepinephrine. Originally developed for Alzheimer's and Parkinson's disease, it was repurposed as a potent weight loss agent after clinical trials demonstrated substantial fat loss via appetite suppression and increased energy expenditure.

- 0.01–0.1% (4–8 mg/g in clinical studies)
- 0.25-0.5 mg per day
- Frequency
- Twice daily
- Once daily
- Key Benefits
- Reduces depth of dynamic wrinkles and expression lines
- Reversible muscle-relaxing effect on facial muscles
- Smooths forehead lines, crow's feet, and frown lines
- Non-invasive alternative to injectable neurotoxins
- Rapid onset relative to collagen-stimulating peptides
- Well-studied in in vitro and clinical cosmetic trials
- Potent appetite suppression via triple monoamine reuptake inhibition
- Significant weight loss (8-12% body weight in phase II trials at 0.5 mg)
- Increases basal metabolic rate and energy expenditure
- Reduces fat mass preferentially over lean mass
- Potential cognitive benefit via dopaminergic and noradrenergic enhancement
- Longer half-life than sibutramine allows once-daily dosing
- Side Effects
- Generally very well-tolerated topically
- Rare skin sensitivity or contact dermatitis
- Theoretical neuromuscular effects at systemic doses (not relevant topically)
- Elevated heart rate and blood pressure (sympathomimetic)
