GHOST x Sour Strips Appleberry: Creatine and Legend Join the Collab

The GHOST x Sour Strips Appleberry collab is complete. GHOST Creatine takes the tart apple and sweet berry into a 40-serving tub, and GHOST Legend carries the leaner 200mg caffeine formula rather than V4. Both go live September 9th alongside the Energy can.

GHOST and Sour Strips are extending their Appleberry collaboration to two more products. GHOST Creatine and GHOST Legend are picking up the tart apple and sweet berry flavor that GHOST Energy and Sour Strips introduced on August 7th, with product packages arriving around August 28th and the full lineup launching on GHOST's DTC site, Amazon, and select specialty retailers on September 9th.

This marks GHOST's ninth collaboration with Maxx Chewning, the fitness personality and Sour Strips founder who's partnered with the brand since 2020. The partnership settled into an annual rhythm under the Sour Strips name starting in 2023, with Rainbow carrying the collection for three straight years before Appleberry finally broke the streak this year as the partnership's first new flavor since it went annual.

The Appleberry Lineup Grows

Here's what's joining the collection:

• GHOST Creatine, the brand's single-ingredient daily creatine pick, now available in its 40-serving Appleberry tub.
• GHOST Legend, the brand's flagship pre-workout, carrying the leaner formula with 200mg caffeine that GHOST has been testing through recent limited-edition collabs, as opposed to the massive standard V4 recipe still sold in Legend's regular flavor lineup.

Both products join the same three-item Appleberry family as the already-live GHOST Energy Appleberry can, rounding out the collection GHOST teased when Energy launched earlier this month.

GHOST Creatine Sour Strips Appleberry

GHOST Creatine picks up Appleberry as a straightforward flavor carryover, no formula changes involved. The product only recently got its own dedicated formula overhaul, swapping in TSI Group's OptiCreatine for better mixability, so Appleberry arrives on a formula that's still brand new itself.

Each 9g scoop provides 5000mg of OptiCreatine Creatine Monohydrate, the same single active ingredient GHOST has run since the July 2026 relaunch. This is TSI Group's version of creatine monohydrate, and it's far more soluble and dispersible in water.

At 5 calories and under a gram of carbohydrate per serving, it's built to disappear into whatever you're already drinking, whether that's water or another GHOST product. We covered the full switch from Creapure to OptiCreatine, including why solubility was the entire point of the change, in our GHOST Creatine article.

GHOST Legend Sour Strips Appleberry

GHOST Legend brings something more interesting than a flavor swap. This Appleberry version doesn't run the standard V4 formula still selling in Legend's regular flavor lineup (at least for now).

Instead, it carries the leaner, 200mg-caffeine version that GHOST first tested a few weeks earlier through its Sydney Cummings Mango Colada collaboration. GHOST has used limited-edition collabs as a testing ground for formula changes since the brand's early days, and this marks the second time this particular version has shipped, though GHOST hasn't confirmed it as a permanent replacement for V4 yet.

One 22.5g scoop provides the same core Legend actives at their usual doses: L-Citrulline at 6000mg, Beta-Alanine at 3200mg, and Betaine Anhydrous at 2500mg for pump and endurance, alongside L-Tyrosine at 2000mg, taurine, and choline for focus.

The headline change from standard Legend is caffeine, dosed here at 200mg of natural caffeine rather than V4's 300mg, plus 135mg of vitamin C as plain ascorbic acid. We broke down exactly what moved between this formula and V4 in our Sydney Cummings coverage linked above, and you can find the full ingredient science behind Legend's core actives in our main Legend deep dive.

The Full Appleberry Lineup

Here's every product carrying the flavor at a glance:

The three fit into different parts of a routine rather than competing with each other: Creatine as a daily add-in whenever you mix it, Legend before training, and Energy whenever a canned pick-me-up beats scooping powder.

Conclusion: Appleberry Completes the Set

Ghost Energy and Sour Strips are back for year four, and they finally ditched Rainbow. Appleberry brings tart green apple and sweet berry into a 16oz can with 200mg caffeine and zero sugar.

GHOST's Appleberry run with Sour Strips now spans all three products the brand teased when Energy launched earlier this month, closing out the ninth collaboration between GHOST and Maxx Chewning (although it's worth noting that he sold Sour Strips). Creatine brings the flavor to GHOST's simplest supplement, a single 5000mg scoop of creatine and nothing else, while Legend brings it to the flagship pre-workout, wearing a formula GHOST is still quietly testing out through collabs like this one rather than rolling out across the standard lineup.

Everything here is limited edition and tied to the same September 9th nationwide launch that GHOST Energy Appleberry already kicked off, so don't expect Creatine or Legend's Appleberry tubs to stick around once they sell through.
