Questions & Answers
How does Persef work?
At Persef, we make low-sugar dark chocolate bites that quietly carry a clinically informed longevity stack inside. Each 18g bite is 60% cacao with just three core chocolate ingredients - cocoa mass, cocoa butter, and coconut sugar - under 100 calories and designed to support daily strength, focus, and body confidence with creatine plus vitamins C, D, K, B6, B12, and folate.
Your order arrives as a monthly supply of 28 individually wrapped bites, so your routine is simple: one piece a day, with coffee, after a meal, or whenever your chocolate ritual naturally fits. Consistency matters for long-term benefits, so Persef is offered as a monthly or quarterly subscription, built to help you actually stick with it.
Each batch is made in small runs with high-quality cacao and carefully sourced actives, formulated at meaningful doses rather than an alphabet soup of unnecessary extras. You get real nutrients and real chocolate: no fillers, no gimmicky candy-aisle shortcuts.
Join Persef and turn a daily dark chocolate you look forward to into a habit that supports your future self, one delightful bite at a time.
What does Persef Chocolate taste like?
Persef tastes like a proper 60% dark chocolate you’d buy for pleasure, not a vitamin disguised as candy. It’s rich and cocoa-forward with gentle sweetness from coconut sugar and vanilla, closer to a premium European dark bar than a protein snack.
Each 17g bite is thick and breakable, so you get a satisfying snap and a smooth, slow melt rather than anything chalky or powdery. You mainly taste chocolate; the creatine and vitamins are formulated so they don’t leave a weird aftertaste.
If you already enjoy good dark chocolate but want something lower in sugar and under 100 calories, Persef should feel like an easy upgrade, familiar, indulgent, and grown-up.
How do you handle returns or exchanges?
We want you to have the best possible experience with Persef. While returns are rare, we offer a simple and flexible policy to give you peace of mind. You can return any unopened chocolate truffle bags within 30 days of your first order for a refund or exchange.

Please note: this policy applies only to your initial purchase.
What are the full set of ingredients?
Each serving (1 bite) contains:
Cocoa paste, cocoa butter, coconut sugar, creatine monohydrate, sunflower lecithin, vanilla powder, vitamins K & D, vitamins B6 & B12, folate.
When will I see an improvement?
The timeline for feeling the benefits of Persef varies from person to person. Some people notice changes in how they feel, steadier energy, better workouts, and a clearer head, within a couple of weeks. For others, the effects are more gradual and subtle.
What matters most is consistent daily use. Persef is built around the key supplement stack (Creatine, D, K, B6, B12 and folate), which work best when your body’s stores are topped up over time, not from a one-off dose.
As you take Persef daily, creatine helps saturate your muscles and brain, supporting strength, power output, and mental focus. The B vitamins and folate support energy metabolism, while vitamins D and K help maintain bone and overall health. Think of it as the ideal foundational stack that helps your body do its job better over the long term.
First 1–2 weeks: most people mainly notice the ritual, a satisfying dark chocolate bite that replaces a more sugary snack. Some also feel a bit more “there” in workouts or during long days.
Around weeks 3–4: creatine levels in muscle and brain are typically saturated, so support for strength, endurance, and cognitive performance is at its best, as long as you keep taking it.
Beyond 4–8+ weeks: the benefits are maintenance, helping you hold onto strength, support brain and nervous system health, and generally feel more capable as the years add up.
Because these are cumulative, inside-out effects, Persef is designed as a long-term daily ritual rather than a quick fix: a small, enjoyable habit that helps your future self, one bite at a time.
