THCA Profile of Starfruit x Wilson #36 – Lab-Tested Potency and ContextStarfruit x Wilson #36 Live Rosin – Pheno-Specific Potency

The Starfruit x Wilson strain (pheno #36) has been released as a Cold Cure Live Rosin by Los Angeles Hash Co., and it boasts very high THCA content. This exclusive phenotype – a cross of Starfruit (Sensi Star × AK-47) and Wilson (Banana OG × Papaya × Tropicana Cookies) – is a small-batch, drop-only offering selected for its unique terpene profile and potency. According to the producer’s description, the Starfruit x Wilson #36 rosin is “High THC – ~70–75%” by weight. Although a full certificate of analysis (COA) isn’t shown on the site, this figure indicates an exceptionally high THCA percentage in the concentrate (since in solventless rosin most “THC” is present as THCA prior to decarboxylation). In practical terms, a ~70–75% total THC potency suggests the raw THCA content in this rosin is likely on the order of ~80% or higher by weight (with minimal Δ9-THC before use). The product is sold in 1g jars (also 2g/4g options) and was priced around $45 per gram for the top-tier batch. Pheno #36 is noted as “only one like it,” underscoring that it comes from a specific hunted phenotype rather than a broad production run.

Lab Testing Data and THCA vs. Total Cannabinoids

While Los Angeles Hash Co. has not published a public COA for the Starfruit × Wilson #36 batch, we can infer its laboratory profile from similar products. THCA likely makes up the vast majority of cannabinoids in this live rosin, with only trace Δ9-THC (to remain Farm Bill compliant) and minimal other cannabinoids. For context, high-quality hash rosin examples often show THCA in the high-70s to low-80s percent range. In one case, a Jet Fuel Gelato cold-cure hash rosin tested at ≈80.78% THCA out of ~83% total cannabinoids (with essentially no delta-9 THC prior to decarb). This corresponds to roughly 70.8% total THC potential after full decarboxylation. By analogy, if Starfruit x Wilson #36 rosin is in the “70–75% THC” range as listed, its actual THCA content is likely around 80–85% of the extract (since THCA’s molecular weight causes about a 12-13% loss when converting to THC). In other words, nearly all of the product’s cannabinoids are THCA, with perhaps a few percent coming from minor cannabinoids or terpenes. This THCA-dominant profile is typical for premium solventless concentrates: the THCA percentage is only slightly lower than the “total cannabinoids” figure. For instance, the Jet Fuel Gelato rosin’s ~80.8% THCA was out of ~83% total cannabinoids – illustrating that THCA comprised the bulk of cannabinoids present (and the remainder were minors like CBGA, etc., plus terpenes which don’t count toward cannabinoid percentage). We can expect the Starfruit × Wilson #36 rosin to show a similar pattern, e.g. on a lab report it might read ≈80% THCA, <0.3% Δ9-THC, with total cannabinoids in the low 80s%. Such a result would align with the producer’s “70–75% THC” potency estimate once one accounts for THCA-to-THC conversion.

Note: Los Angeles Hash Co specializes in hemp-derived “THCA” extracts, meaning the product is lab-tested to ensure Δ9-THC is under 0.3% by dry weight. This ensures legal compliance while delivering high THCA levels. So, any official lab report (if provided) would likely be from a third-party lab verifying that nearly all the THC is in acid form. In summary, the #36 Starfruit × Wilson rosin delivers cannabinoid potency on par with top-shelf concentrates, with THCA composing essentially all of the ~70–75% total THC content by weight.

Comparative THCA Figures from Similar Hybrids

In the absence of a published COA specifically for Starfruit × Wilson, we can look at similar Wilson or Starfruit hybrid extracts for reference. Other solventless hashmakers’ lab results show that crosses involving Wilson tend to produce rosin with high THCA percentages (typically in the 65–75% THC range):

• Sour Diesel × Wilson #6 Rosin (Olio, Colorado): A cold-cured hash rosin made from Sour D (BX) × Wilson #6 tested at 70.7% THC with about 0.2% CBD. This product (by Olio) is a sativa-hybrid rosin and the lab profile indicates essentially all of that 70.7% is THCA (plus a trace CBD), since Δ9 was negligible. This potency level is very close to what’s expected from Starfruit × Wilson #36, reinforcing that well-made Wilson hybrids routinely hit ~70%+ cannabinoid strength in rosin form.

• “Chilly Willy” Live Rosin (Frosted Fruit Cake × Wilson! Zero by Sauce Rosin Labs, Canada): This solventless extract – which actually includes Starfruit lineage in its flavor notes – came back with THC ~67.5% and CBD ~0.22% in official lab testing. Chilly Willy is an in-house cross of F.F.C. (Frosted Fruit Cake) × Wilson Zero, and its COA-listed THC content was ~67.5% for a 1g jar. Nearly all of that is THCA (with only 0.22% CBD and essentially no Δ9-THC). This shows a comparable ballpark: high-60s to low-70s % THC is common for these terpene-rich solventless products. The Starfruit × Wilson #36 rosin, being a similar fresh-frozen hash extraction, likely matches or exceeds those numbers (as implied by the ~70–75% range given by LA Hash Co).

• Wilson Strain Potency (Flower Perspective): For context, the parent Wilson (a Papaya/Banana OG hybrid by Masonic) is known to test in the mid-20s THC in top-shelf flower form – with some phenos hitting 25–28% THC under optimal conditions. Starfruit (the other parent) is typically a ~20% THC strain in flower. Thus, it’s unsurprising that a well-selected phenotype from this lineage could produce concentrates with very high THCA density. In concentrates, the cannabinoid content is essentially “amplified” by isolating trichomes and oils – so seeing 70%+ potency in rosin made from a ~25% THC cultivar is reasonable.

In summary, lab-verified data from similar crosses confirm the potency of Starfruit × Wilson #36. Its THCA content is expected to be in the same elite range (~70–75% total THC, predominantly as THCA) as other Wilson-family solventless extracts. This pheno #36 was a limited release, so official numbers are scarce, but all available indicators – from the producer’s own notes to analogous COAs – point to THCA in the high 70s% of the extract and a total cannabinoid content only a few percent higher than the THCA figure. The result is a terpene-rich, creamy funk rosin that delivers both exceptional flavor and a powerhouse cannabinoid profile.
