Rockstar (S-LAB and Tilray): nerolidol, Sensi Star in the lineage and three entries

What is Rockstar and where does this strain come from?

Rockstar is an indica cultivar, whose parents are Rock Bud and Sensi Star. The lineage is established, and the same pair is repeated by several independent strain databases, so Rockstar does not belong to those twenty-five cases in the cluster where the origin remains unknown. Both sources used for this project describe the genetics as indica.

The lineage record comes from three strain catalogs. Strainpedia, AllBud, and SeedFinder provide the same parent pair, and the latter maintains an entry under the breeding of Bonguru Beans. The agreement of three separate records is significant here, because in the same comparison, twenty-five cultivars out of eighty-five have no established origin at all: the breeder did not disclose it or the available databases contradict each other. Where this is the case, we state it directly, rather than filling the gap with assumptions.

The similarity of names can be misleading, and here it seems to lead in the right direction. Rockstar shares the first part with Rock Bud, and Sensi Star ends with the same word as the strain name, but the kinship comes from the record in the databases, not from a shared syllable. If the name were sufficient as evidence, every cultivar with the element "star" would be considered a descendant of Sensi Star, but that is not the case: in this comparison, kinship arises solely from the record of the parents, never from phonetic similarity.

Which producers supply Rockstar to Polish pharmacies?

Two: S-LAB and Tilray. In the collected inventory, they correspond to three registration entries, as S-LAB offers this strain in two declared strengths, while Tilray offers it in one. The current assortment and prices are solely in an updated list of available strains, because both of these things change faster than the strain description.

The declared THC content is not a single number. The entries differ in strength, and the manufacturer has a ten percent tolerance for the values on the packaging, so the total range for all three Rockstar entries is 16.2-24.2%. Providing just the nominal value would suggest precision, which is not present in the documentation: a batch compliant with the declaration may lie at either the lower or upper end of this range, and the patient will not know the analysis result of their package.

Availability is not a characteristic of the strain, but a state of stock. In the collected data, all three entries had a marker for lack of availability in the source, which does not mean that the strain has disappeared from the market permanently, nor that it will not return with the next import. Therefore, no entry in this cluster leads its own availability list. It is also worth separating two things with similar names: the pharmacy raw material dispensed by a doctor's prescription is different from dried hemp available over the counter in retail.

What does Rockstar smell and taste like?

All three catalog descriptions agree only on the peppery note. Apart from that, they diverge: one entry carries a spicy accent with fruity and herbal, the second earthy with minty, the third combines spicy with minty. These are commercial descriptions, not results of sensory analysis, and should be read as such.

The aroma is determined by the volatile composition, which is described for Rockstar by one source. The taxonomy includes seven entries: bisabolol, humulene, caryophyllene, limonene, linalool, myrcene and nerolidol. Since they are described by one database, there is nothing to compare them with, and it is unclear whether another would indicate the same set.

The source provides a numerical share for each entry, which we do not transcribe. The reason is simple: shares in Polish databases do not add up to a whole, and their sum can vary in each comparison, so it is unclear what stands in the denominator of such a fraction. A number without a known denominator appears to be a measurement, but it is not. Therefore, we present the composition as it is, and we only mention that nerolidol ranks highest in this record.

There is also a detail that is only visible when comparing three entries side by side: the terpene record is identical in value, although the aroma descriptions differ. This means it has been assigned to a strain rather than a tested batch, and it cannot replace the analysis of a specific pharmacy batch.

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

There is no such measurement for Rockstar itself. The onset of effects and the duration of the episode depend primarily on the method of intake, and only subsequently on what is growing in the pot. No publication has tracked blood concentrations after consuming this specific dried flower.

The route of administration determines the course more than the variety itself. After vaporization, the substance passes from the lungs to the blood almost immediately, so the first sensations appear after a few minutes, the intensity increases for another ten to thirty minutes, and the whole effect lasts for two to four hours. After ingestion, the raw material first passes through the intestine and liver, so the first sensations are awaited from half an hour to two hours, and the episode can last six, sometimes eight hours. Hence the most common mistake with oral administration: anyone who thinks nothing is happening after thirty minutes and takes another dose will receive both doses at once. The above ranges describe the route of administration, not this variety; pharmacokinetic studies for a single cultivar have not been published.

The method of intake is determined by the prescribing physician, as dried flower is dispensed by prescription. The above numbers serve to understand why the same dose behaves differently depending on the method of administration, rather than for independently establishing a dosing scheme.

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

Research-wise, almost nothing is known about Rockstar. The publications that can be referenced here describe a single terpene from its profile, not the cultivar, and were conducted on rodents. The rest of the circulating descriptions come from sales materials or patient reports, which are a completely different type of information.

In the evidence base of this project, nerolidol corresponds to two entries. The first was authored by Fonsêca et al., published in 2016 in the journal "Fundamental & Clinical Pharmacology" (PMID:26791997). In this study, mice were administered nerolidol at doses of 200-400 mg/kg, after which abdominal contractions were counted in the acetic acid test: there were fewer, and the concentrations of two inflammatory proteins, IL-1beta and TNF-alpha, also decreased in the tissues. The observed analgesic effect was attributed more to GABA signaling than to opioid receptors. The second, from 2026, was published by Hojjat et al. in the journal "Arquivos de Neuro-Psiquiatria" (PMID:42447923): there, the mouse received nerolidol orally at doses of 25-100 mg/kg and required more time before pentylene tetrazole induced seizures, with lower brain markers of oxidative stress.

It has not been shown that nerolidol alleviates anxiety or insomnia in humans; both available studies concern rodents and describe analgesic, anticonvulsant, and antioxidant effects, not sleep or mood.

On the other side is commercial material. The catalog source assigns the same possible effect to all three entries, described as relaxing, and there is no publication backing this statement. The result obtained in mice after a dose calculated per kilogram of body weight cannot be translated to inhaled dried flower in humans. The separation of these two orders is the entire content of this section: what was measured and on whom, and what was merely written in the product description.

What side effects have been reported for this strain?

Separately for Rockstar, there are none, and there is no source to obtain them from. Safety oversight in Poland is conducted at the level of packaging and batches, so public compilations do not break down reports by trade names of cultivars. The following description thus covers dried flower treated as a group of raw materials, not just this one strain.

Reports of adverse effects are collected for medicinal products with a batch number, not for the strain name, so the following pertains to hemp dried flower as a group of raw materials. The most frequently reported symptoms are dry mouth, red eyes, and increased heart rate. Dizziness upon rapid standing, daytime drowsiness, and temporary worsening of short-term memory are less frequently described, as well as anxiety that increases with dosage. A separate issue is medications taken concurrently, especially sedatives and those affecting coagulation: their assessment requires knowledge of the entire list of preparations, not just the description of the plant. We do not provide the frequency of these symptoms numerically, as public compilations for hemp dried flower in Poland do not separate them by individual products.

A list of symptoms assigned to a specific strain would appear more precise than the above, but it would be fabricated: the data from which it would arise are not collected by cultivar. We prefer to state this directly rather than create a unique profile of side effects for Rockstar that no one has measured.

How to vaporize this strain?

Temperatures suitable for nerolidol cannot be provided, as the public database does not contain values comparable to other terpenes. The method of intake is also determined by the prescribing physician: dried flower is a pharmaceutical raw material dispensed by prescription, and this entry describes the state of knowledge, not a recommendation.

The public database PubChem has exactly one entry for nerolidol stating 275-277 degrees Celsius; it comes from a JECFA compilation and is not accompanied by information about the pressure at which the measurement was made. Boiling temperature depends on pressure, so a number lacking this information should not be placed in the same column as atmospheric values. In Rockstar's profile, the same issue applies to humulene: the database notes 99-100 degrees, but the measurement was taken at a pressure of 3 mm Hg, thus in a laboratory atmosphere. Bisabolol is not described at all.

The very concept of terpene temperature is misleading. The substance also transitions to vapor at temperatures lower than boiling, and the rate of this transition increases smoothly with heating, so there is no threshold at which vaporization begins. A separate issue is the difference between the device setting and the temperature of the dried flower itself, which can be cooled by airflow when inhaled. Both threads are developed in a post about the evaporation of terpenes from dried flower.

Which strains are related to it?

In Polish pharmacies, none. Neither Rock Bud nor Sensi Star appears in the lineage of any other of the eighty-five cultivars collected in this cluster, so the pedigree graph leaves Rockstar without siblings. The empty list here is the result of verification, not a gap in the data.

Strains sharing the leading terpene are often considered related, but this is a completely different axis. Nerolidol ranks highest in the record of several other entries from this comparison, including Galaxy Walker OG and Pink Kush, but the common terpene speaks to the volatile composition, not to lineage. A complete list of strains with this terpene is maintained in a separate entry about nerolidolu.

If any of the parents ever made it to the Polish market, this section will receive a reference. Adding siblings by intuition creates connections that no one later clarifies, and the pedigree graph ceases to mean anything. Until such a change, Rockstar's neighborhood defines not the pedigree, but who supplies it: S-LAB and Tilray. Both have significantly broader lists of varieties in the Polish market, and it is there, not in the pedigree, that the closest surroundings of this entry can be found.

Frequently Asked Questions about the Rockstar variety.

Is Rockstar available in Polish pharmacies?

Rockstar appears in the collected inventory in three entries from two producers, but the availability of a specific batch changes from import to import, and at the time of data collection, the source indicated all three as unavailable. The current state carries only an updated list of varieties, not a description of a single variety.

What THC content does Rockstar have?

Declarations for individual entries vary, and the producer has a ten percent tolerance for the value stated on the packaging. Combining both of these factors, the total range for Rockstar is 16.2-24.2%. A single number would suggest accuracy that the registration documentation does not provide.

What terpenes are described in Rockstar's profile?

The record includes seven entries: bisabolol, humulene, caryophyllene, limonene, linalool, myrcene, and nerolidol, with nerolidol ranking highest among them. They are described by a single database, so there is no comparison between sources. We do not transcribe percentage shares because the denominator of these fractions remains unknown.

Does Rockstar help with sleep or anxiety?

There is no study that demonstrates this. The available research on nerolidol was conducted on mice and pertains to pain, seizures, and oxidative stress, not sleep or mood. Catalog descriptions attributing relaxing effects to this variety are marketing material, not measurement results.

What is Rockstar's lineage?

The parents are Rock Bud and Sensi Star, and this same pair is repeated in three independent cultivar catalogs. Therefore, Rockstar belongs to that part of the cluster where the origin is established, not to the twenty-five cultivars with lineage described as unknown.

Does Rockstar have related varieties in Polish pharmacies?

No. None of the eighty-five cultivars collected in this cluster shares a parent with it: neither Rock Bud nor Sensi Star appears in any other pedigree. Varieties with the same leading terpene are not relatives, but neighbors on the composition axis.
