I ran Waklert and Artvigil back-to-back for the first time in years. I expected the gap to be minimal, same compound, different label. It wasn't. Waklert kicked in around 40 minutes. Artvigil took closer to 50 and peaked noticeably lower. Not weaker in a way that mattered. Smoother in a way that did. I've retested both many times since. The gap holds every time. My personal favourite is Artvigil.
Both Waklert and Artvigil contain 150mg of armodafinil. Waklert (Sun Pharma) hits faster and peaks harder, making it the stronger option for experienced users. Artvigil (HAB Pharma) has a more gradual onset and softer peak, which suits beginners or anyone sensitive to stimulants. Both last 10 to 15 hours.
How This Comparison Was Made
Shane Hellmrich, who studied Health Promotion at Curtin University, has been personally ordering and comparing armodafinil generics since 2016. This comparison is based on documented side-by-side testing of Waklert 150 and Artvigil 150 ordered from verified vendors.
Observable criteria used for comparison: cognitive onset time from ingestion to first noticeable effect (measured in minutes), peak intensity rating on a consistent personal scale, duration of the focused work window in hours, presence and severity of side effects including jitteriness and appetite suppression, and quality of the comedown or return to baseline.
Vendors not listed were excluded for one or more of the following reasons: unresolved reshipping disputes, payment failures reported across multiple accounts, verified counterfeit reports, or confirmed closure at time of writing. No vendor is listed that Shane has not personally ordered from.
What Is Armodafinil?
Armodafinil is the R-enantiomer of modafinil. Cephalon developed it under the brand name Nuvigil and the FDA approved it in 2007, four years after the original modafinil patent expired. The pharmaceutical logic was straightforward: isolate the longer-lasting of the two modafinil enantiomers, patent it separately, and extend market exclusivity.
The practical result for users is a compound that delivers a longer, cleaner effect curve at a lower milligram dose. A 150mg armodafinil dose is commonly compared to a 200mg modafinil dose in terms of subjective strength, though the pharmacokinetic profiles are different enough that the comparison is not exact.
Armodafinil's extended half-life means the effect curve is flatter and more sustained than modafinil. That is both its advantage and its risk: the same quality that makes it last longer also makes it more likely to disrupt sleep if taken too late.

Waklert vs Artvigil: Full Comparison
The table below covers the factual and experiential differences between the two products based on documented testing and published pharmacokinetic data.
The Product Profiles
Waklert 150
Sun Pharma is the same manufacturer behind Modalert 200, the most-used modafinil generic on the market. Waklert carries the same manufacturing heritage: consistent batch quality, recognisable packaging, and wide availability across verified vendors.
The subjective experience is typically described as more intense than Artvigil, with a sharper onset and a higher peak. For most experienced users this is the appeal. The sharper profile is also what makes Waklert less suitable for first-time armodafinil users.
- Faster onset, typically 45 to 60 minutes post-ingestion
- Longer effect window, up to 15 hours in some users
- Sun Pharma's batch consistency reduces quality variation across orders
- Familiar manufacturer for anyone who has used Modalert
Artvigil 150
HAB Pharmaceuticals is a smaller Indian generic manufacturer with a narrower product range than Sun Pharma. Artvigil is their most widely ordered product globally. Batch quality is generally consistent, though users occasionally report more variation than with Sun Pharma products.
The subjective experience is smoother and more gradual. Onset takes longer, the peak is less pronounced, and the drop-off back to baseline tends to be gentler. For many users this profile is preferable, particularly those who find Waklert's intensity difficult to manage.
- Gradual onset, typically 60 to 90 minutes post-ingestion
- Shorter effect window, 10 to 12 hours for most users
- Lower sleep-disruption risk if taken in the morning
- Lower cost per pill across most vendor pack sizes
Speed of Onset: Which Kicks In Faster?
Is Waklert noticeably faster than Artvigil?
Yes, in consistent personal testing. Waklert onset runs 45 to 60 minutes from ingestion on an empty stomach. Artvigil typically runs 60 to 90 minutes under the same conditions. The gap narrows when either is taken with food, which slows absorption for both.
The onset difference is not just a timing gap. Waklert's faster onset produces a more noticeable transition into the focused state. Artvigil's slower onset makes the shift less obvious, which some users find easier to work with.
Peak Intensity: Is Waklert Actually Stronger?
Does Waklert feel more powerful than Artvigil?
Yes, based on consistent personal testing and reported user experience across years of orders. Both products contain identical milligrams of the same active compound. The intensity difference appears to be formulation-driven, not compound-driven, though the exact pharmacokinetic mechanism is not documented in published literature for these specific generic products.
In practice, Waklert produces a more pronounced peak of focus and wakefulness. Artvigil produces a sustained but lower-amplitude effect. Neither is better in an absolute sense. The right choice depends on the task and the user's tolerance.
The intensity difference between Waklert and Artvigil is real and consistent across multiple testing cycles. It is not dramatic, but it is noticeable. Experienced users will feel it. First-time users may not have the baseline to detect it.
Half-Life and Sleep Disruption: Which Is Safer to Take Later?
Does Waklert disrupt sleep more than Artvigil?
Yes, typically. Armodafinil's published half-life is 12 to 15 hours for the R-enantiomer. In practice, Waklert's effect tail runs longer than Artvigil's for most users. Taking Waklert after 8am creates measurable sleep disruption risk for people who sleep at midnight. Taking Artvigil before 9am is generally safe for the same schedule.
The practical rule: take Waklert before 7am. Take Artvigil before 8am. Both benefit from a consistent schedule. Sleep tracking data from users consistently shows Waklert correlates with later sleep onset and reduced deep sleep quality when taken after 8am. For a full protocol including timing, read the modafinil and armodafinil dosage guide.
If your schedule forces you to take your dose later in the morning, Artvigil is the more practical choice. Its shorter tail means the sleep window is less likely to be compromised.
Most users on a 5-days-on, 2-days-off protocol find a 100-pill pack of either product lasts 3 to 4 months. Restocking every quarter is the most common cycle.
Which Should You Choose?
The direct answer depends on your situation. Use the scenario grid below.
You are new to armodafinil
Start with Artvigil. The smoother onset and lower peak intensity reduces the chance of a difficult first experience. Build your baseline before moving to Waklert.
Choose ArtvigilYou have used modafinil before
Either works. If you found Modalert too mild, start with Waklert. If Modalert was plenty strong, start with Artvigil to assess how armodafinil feels for you personally.
Try Artvigil FirstYou need maximum duration for a long day
Waklert's 12 to 15 hour window is the better fit. Take it before 7am with water, no food. The extended tail matches a 16-hour productive day.
Choose WaklertYou are sensitive to stimulants or prone to jitteriness
Artvigil is the clear choice. Its lower peak amplitude and slower onset profile produces a less stimulant-like experience. A 75mg half-dose is also easier to achieve with Artvigil's tablet scoring.
Choose ArtvigilBudget is your primary constraint
Artvigil is cheaper across most vendor pack sizes by 15% to 20%. At high volume (200+ pills), the saving is meaningful. The gap widens further with FreeModafinil's sample program.
Choose ArtvigilYou have experience with both and want the stronger option
Waklert. Sun Pharma's formulation consistently produces a more pronounced and longer-lasting effect. If you know your tolerance and work best with higher intensity, this is the one.

Frequently Asked Questions
Is Waklert stronger than Artvigil?
Yes, in terms of peak intensity and onset speed. Waklert (Sun Pharma) hits faster and produces a more pronounced focus peak. Artvigil (HAB Pharma) delivers a smoother, more gradual effect at a lower peak amplitude. Both contain 150mg of armodafinil, so the difference is formulation-driven, not compound-driven.
Can you cut Artvigil in half?
Yes. Artvigil 150mg tablets are scored and can be split cleanly into two 75mg doses. This makes Artvigil the better option for new users who want to start at a lower dose before committing to a full 150mg. Waklert tablets are also splittable but the tablet geometry makes a clean break less consistent.
Which is better for beginners: Waklert or Artvigil?
Artvigil is the better starting point for beginners. Its smoother onset and lower peak intensity produce a less overwhelming first experience. Start at 75mg (half tablet) and assess your response before moving to a full 150mg dose. If Artvigil at 150mg feels manageable, you can then evaluate whether Waklert's stronger profile is useful for you.
Does Waklert or Artvigil last longer?
Waklert lasts longer. Most users report an effect window of 12 to 15 hours with Waklert, compared to 10 to 12 hours with Artvigil. The difference has practical consequences for sleep: Waklert taken after 8am is more likely to delay sleep onset than Artvigil taken at the same time.
Are Waklert and Artvigil the same price?
No. Artvigil is typically 15% to 20% cheaper per pill than Waklert across most vendor pack sizes. The gap is consistent across ModafinilXL, FreeModafinil, and HighStreetPharma. For long-term use at high frequency, the cost difference adds up meaningfully over a year.
Which armodafinil causes less anxiety: Waklert or Artvigil?
Artvigil is less likely to produce anxiety for sensitive users. Its lower peak intensity and smoother onset profile mean the stimulant-like aspects of armodafinil are less pronounced. Users who report jitteriness or anxiety on Waklert often find Artvigil at the same dose is well-tolerated. For anyone prone to stimulant sensitivity, start with Artvigil at 75mg.
What is the generic name for Waklert 150 mg?
The generic compound name is armodafinil. Waklert 150mg is a branded generic manufactured by Sun Pharmaceutical Industries, containing 150mg of armodafinil per tablet. In the United States, armodafinil is sold under the brand name Nuvigil by Jazz Pharmaceuticals. Waklert is the Sun Pharma equivalent produced for international markets at a significantly lower price point.
Is Artvigil stronger than modafinil?
Not straightforwardly. A 150mg armodafinil dose (Artvigil) is broadly comparable to 200mg modafinil in subjective effect, because armodafinil is the longer-acting R-enantiomer. The profile is different rather than simply stronger: Artvigil has a flatter, more sustained curve compared to modafinil's sharper peak and shorter window. Most users who switch from modafinil describe armodafinil as cleaner and longer-lasting rather than more powerful.
