Master Kush (S-LAB, Synoptis Pharma, Tilray): earthy-peppery aroma with a hint of camphor

What is Master Kush and where does this strain come from?

The lineage of Master Kush is undetermined. None of the available sources provide the parents of this cultivar, so in the lineage graph of the project, it stands with the value 'unknown'. It is known, however, that Polish pharmacies sell it as indica dried flower, and the available registered items come from three producers.

The name is not proof of kinship. In this cluster, the term 'kush' is associated with ten cultivars, half of which have established parents, and half do not have any. Adding Master Kush to any of these families solely based on the name would create a connection that no one has confirmed, and that connection would begin to live its own life in subsequent studies.

What can be said without guessing: the available descriptions consistently classify this dried flower as indica. The declared THC content in the range of 16.2-24.2% arises from the fact that there are registration entries with different nominal values in circulation, and for each nominal value, the manufacturer adds a tolerance of around ten percent of the value. Providing a single number would mimic a measurement that the pharmacy does not perform.

Availability can be unstable. Some registration entries disappear from circulation and return after months, as it depends on imports and whether the manufacturer maintains a given potency in their offer. The current state of the shelves shows a comparison of strains available in Polish pharmacies, maintained separately from this description.

Which manufacturers supply Master Kush to Polish pharmacies?

Three: S-LAB, Synoptis Pharma, and Tilray. Each of them introduces its own registration entry, and S-LAB has two with different nominal values. The versions are not interchangeable, as the source describing their composition provides a completely different terpene profile for Synoptis Pharma than for the other two.

The difference between the versions is not cosmetic. The same base describes the Synoptis Pharma entry as dried flower, where myrcene leads, and caryophyllene is far behind, while the S-LAB and Tilray entries have the opposite record. The trade name sounds the same, although the composition record does not. Until someone publishes results from the same laboratory for all three manufacturers, this discrepancy should be read as a difference in the database record, not as a measured difference between the dried flowers.

The composition of the version is one thing, availability is another. Registered items enter and exit the market independently of each other, so the list of producers valid today may not be valid in a quarter. For this reason, we manage the current assortment in one place, rather than on eighty-five pages about individual strains. Separate descriptions are also provided by the producers themselves: S-LAB, Synoptis Pharma and Tilray.

How does Master Kush smell and taste?

Earthy and peppery, with a cool hint of camphor that can easily be mistaken for the scent of incense. The citrus layer is present but thin and only appears after grinding. It is a spicy profile, not sweet: nothing here resembles fruits or vanilla. This is how the base from which this strain's profile originates describes it.

This aromatic profile is the main reason why Master Kush does not replace Purps, although both strains share the same dominant terpene, the same uncertain lineage, and the same three producers. Purps is described by its appearance and sweetness: purple buds, a grape-berry aroma. Master Kush goes in the opposite direction, with dry pepper and cool wood. Those looking for a fruity flavor will not find it here.

The effects description should be read more cautiously than the aroma description. The base assigns this strain one keyword, relaxing, and nothing more. In descriptive materials, Master Kush comes across as balanced and alert relaxation, lighter than the sedation attributed to Purps. However, this is a commercial characteristic, not a measurement, and there is no study comparing these two strains behind it. The aroma can be described in words and checked upon opening the package, but the character of the effects cannot be verified in the same way, and it is not worth blurring that line.

How long does it take for the strain to take effect and how long does the effect last?

For Master Kush itself, no one has measured this. The numbers that can be provided describe the behavior of THC administered by inhalation or orally and come from pharmacokinetic studies concerning the raw material, not this strain. The difference between the routes of administration is greater than the difference between individual cultivars.

With vaporization, the onset of effects is measured in minutes. Pharmacokinetic literature regarding inhaled THC describes the first sensations a few minutes after inhalation, peak blood concentration around the first quarter-hour, and noticeable effects lasting approximately two to four hours. The reason is the route: the substance passes from the lung alveoli directly into the bloodstream, bypassing the digestive tract.

After oral administration, the same raw material behaves differently. The onset can be delayed by half an hour to two hours, the peak occurs later and is blurred, and the overall duration usually extends from six to eight hours. This is due to the passage through the liver before entering the general circulation, which alters the pace and scale of the response.

None of these numbers is a property of Master Kush and should not be read that way. These are ranges for the method of administration, with a large individual variation, dependent on inhalation technique, equipment setting, and the meal preceding consumption. The vaporizer setting is, by the way, not the same as the temperature of the dried flower, as discussed in a separate text about pomiarze temperatury w komorze.

What is known, and what is not known about the effects of this strain?

It is known which terpene leads in the profile and what has been shown for this terpene in animal models. However, nothing is known about the strain itself: there is not a single clinical study in which Master Kush was administered to patients and the outcome measured. This boundary runs through the entire description below.

The profile composition is described by one source, a Polish database collecting pharmacy position cards. It lists bisabolol, humulene, caryophyllene, limonene, linalool, myrcene, nerolidol, and pinene for this strain. In the records concerning the S-LAB and Tilray versions, caryophyllene is listed first, followed closely by nerolidol; in the record for the Synoptis Pharma version, myrcene is at the top, with caryophyllene far down the list. The second source we use for other cultivars does not describe this strain at all, so there is nothing to compare here.

We do not provide percentage shares next to the names, and this is not an oversight. The measured sums of these shares, calculated for the same positions from Polish databases, are 46%, 73%, and 83%. The denominator is therefore unknown and different in each comparison, and the number placed next to the name of the compound would appear to be a measurement result, which it is not.

Separately stands what has been shown for caryophyllene. The work of Gertsch's team from 2008 (PMID:18574142) showed that this compound selectively binds to cannabinoid receptor type 2 and suppresses paw swelling in mice, but in animals lacking this receptor, the effect disappears. Six years later, Klauke's team (PMID:24210682) described that oral administration alleviated the inflammatory phase of pain in mice and symptoms in a neuropathic pain model, without the development of tolerance.

The boundary of these studies must be stated clearly. In neither of the two studies was caryophyllene tested on humans or in inhaled form from dried flower; both works concern oral or systemic administration in mice in pain and inflammation models, not sleep or mood. Everything said about the effects of Master Kush beyond this comes from commercial descriptions and reports from individuals consuming this dried flower, not from measurements.

What side effects have been reported for this strain?

There are no separate data for Master Kush. No one has maintained a registry of adverse events broken down by cultivars, so the frequencies for this strain simply do not exist. Only numbers for hemp flower as a whole are available, and these do not automatically transfer to a single strain.

Symptoms mentioned with inhalation of hemp flower include primarily dry mouth, dizziness, drowsiness, and increased heart rate, or tachycardia. With higher concentrations of the active substance, anxiety and impaired coordination also occur. None of these positions have been counted for Master Kush separately.

The lack of data is not a formality here. A strain with a high concentration of active substance and a profile described by one database is sometimes presented as if its tolerance were known, but it is not. The decision on the selection of positions is made by the attending physician, and information about contraindications and interactions is carried by the leaflet of the specific package, not the strain description.

Reports go to the monitoring system for adverse effects of medicinal products, but they are recorded there under the product name, not under the cultivar name. Until this level of detail changes, the statement 'after Master Kush, symptom X was reported with frequency Y' will be a fabrication, even if it sounds credible.

At what temperature should Master Kush be vaporized?

There is no single correct value, and the tables circulating online confuse two different things. The boiling point of a pure compound in the laboratory is not the temperature at which the same compound leaves the dried flower in the vaporizer chamber, and the difference can be measured in dozens of degrees.

This is evident with the leading compound of this strain. For caryophyllene, chemical databases report boiling under atmospheric pressure around 257 degrees Celsius, but the same compound has also been measured under reduced pressure, where it transitions to vapor at around 130 degrees. The dried flower is not a pure reagent, and the vaporizer chamber is not a distillation flask, so none of these numbers can be directly translated to settings.

The other compounds in the profile boil significantly lower: pinene around 156 degrees, myrcene about 167, limonene close to 178, linalool at 196. The practical consequence is simple: at lower settings, the vapor carries primarily the lighter part of the aroma, while at higher settings, the heavier, spicy note comes through, which is represented by the leading compound of this strain.

Where the discrepancies between temperature tables come from and why they cannot be reconciled is described in a separate text about the comparability of these comparisons. Sam kariofilen, its studies and their limits are discussed in turn in a section dedicated to this compound.

Which strains are related to Master Kush?

None that could be said based on the data. The pedigree chart in this project connects strains solely through confirmed parents, and Master Kush has none, so not a single edge of kinship emerges from it. An empty list is the result here, not a gap.

It is tempting to add everything here that has the same component in its name. There are ten such entries in the cluster, and the common term does not indicate kinship in either direction: Blood Orange Kush has documented parents, Afghan Kush has none, yet both names appear to be sister strains. Adding edges based on intuition creates a false connection that is then difficult to retract.

Instead of kinship, a comparison based on features remains, and there Master Kush appears three times. Separate texts place it alongside Gorilla Glue oraz obok Galaxy Walker OG, each time for a different reason: once for the profile, once for the pedigree. However, the closest in terms of data is Purps, which has the same leading compound and equally uncertain origin.

If the breeder ever revealed the parents or if two independent sources provided a consistent pedigree, this section would change. Until then, a fair answer remains a lack of response, not a family tree built from a trade name.

Frequently Asked Questions about Master Kush

Is Master Kush an indica strain?

Yes. Available descriptions of pharmaceutical positions consistently classify this dried flower as indica, and there is no discrepancy between sources, unlike the terpene profile itself.

Who supplies Master Kush to Polish pharmacies?

Three producers: S-LAB, Synoptis Pharma, and Tilray. S-LAB has two registered positions of different nominal values, while the others have one each. The shelf composition changes over time, so the current state must be checked in the list of strains available in pharmacies.

Why don't you provide the percentage share next to the compound names from the profile?

Because the published profiles lack a denominator. The total shares that Polish databases provide for the same entries always end up elsewhere and do not add up to one hundred, so the number placed next to the compound name would appear to be a designation that it is not.

Does Master Kush have established parents?

No. The pedigree of this strain is listed as unknown because the breeder did not disclose the parents or the available sources contradict each other. The common component of the name with other entries does not resolve anything here.

How does Master Kush differ from Purps?

In aroma and the character of relaxation. Purps is described by the sweetness of grape and berry and heavy sedation, while Master Kush is characterized by pepper, earth, and cool camphor, and by a lighter relaxation that allows for alertness.

Can this dried flower be purchased without a prescription?

No. Hemp dried flower is a pharmaceutical raw material dispensed by a doctor's prescription in the Rpw category, and this description is for informational purposes only and does not replace the advice of a doctor or pharmacist.
