What Is the Sub Solution From Clear Choice?
Sub Solution is a powder-based synthetic urine product intended to replicate the appearance and basic chemistry of real urine. Clear Choice describes it as a “secret urine formula” made from 11 chemical compounds, including uric acid and urea, and formulated to align with pH, specific gravity, and creatinine targets.
A key reason many buyers prefer this kit is its mix-on-demand format. Unlike pre-mixed products, powder can be stored until needed for a lawful purpose, then prepared using the included components.
Clear Choice also notes that Sub Solution has been on the market since 2003, which is used to reinforce its reputation as a longstanding flagship product.
What’s Included in the Kit?
Sub Solution is sold as an all-in-one package. The kit typically includes:
- Powdered synthetic urine vial
- Heat activator powder
- Mixing container with spout cap
- Temperature strip
- Instructions
This complete kit setup is one of the reasons Sub Solution is frequently categorized as a premium product: it includes the basic accessories that people otherwise have to buy separately.
Formula and Realism: What the Product Emphasizes
Balanced “urine-like” characteristics
Clear Choice and third-party reviews consistently highlight that Sub Solution is built to mirror real urine’s commonly referenced markers, including pH, specific gravity, and creatinine, alongside components like urea and uric acid.
Biocide-free positioning
Sub Solution is repeatedly described as biocide-free, which is framed as an advantage compared with formulas that rely on preservatives.
How It Works
Sub Solution is designed to be mixed from powder and then brought to a realistic temperature using the included materials (notably the temperature strip and heat activator), following the product’s official instructions.
Storage and Handling
Clear Choice notes that Sub Solution can still be managed safely even if you’ve already mixed it but don’t end up using it right away. In that situation, they outline two general storage timeframes—a short-term option and a longer-term option:
-
Short-term storage: The brand indicates the mixed solution can be placed in the refrigerator for temporary holding. This is positioned as the best choice if you expect to use it soon and don’t want to discard the batch unnecessarily.
-
Longer-term storage: For extended storage, Clear Choice states the mixed solution can be frozen. This is presented as the preferred method when the mixture won’t be used in the near future and needs to be kept stable for a longer period.
Why this matters: Most synthetic urine kits are treated as “mix it and use it” products, but Clear Choice’s storage guidance suggests the company expects real-world scenarios where timing changes. That extra flexibility can be a practical advantage for buyers who want a product that doesn’t become unusable immediately after mixing.
Pros and Cons
Pros
Powder-based and mix-on-demand
Powder kits are often preferred for storage and convenience compared with pre-mixed options.
Complete kit
Includes container, spout cap, temperature strip, heat activator, and instructions in one package.
Realism-focused formulation
The product is specifically positioned around matching urine characteristics that are commonly referenced in authenticity checks (pH, specific gravity, creatinine).
Biocide-free differentiator
This is one of the clearest “premium” signals emphasized across the sources.
Cons
Premium price point
Often listed at $95.00, which can be high compared with budget alternatives.
Marketing claims are bold
“100% effective” and “undetectable” appear in product marketing and review-style posts, but those phrases shouldn’t be treated as independent guarantees.
Potential legal and policy risk depending on intended use
Some sites frame synthetic urine around drug testing. Using any substitution product deceptively may violate workplace policies or local laws.
Effectiveness and Reliability
Based on the sources provided, Sub Solution is positioned as a top-tier kit because it’s powder-based, biocide-free, and built around urine-like chemistry targets.
However, real-world outcomes—especially in regulated settings—depend heavily on procedures, rules, and enforcement. Claims like “undetectable” and “100% effective” should be read as marketing rather than certainty.
Legal and Ethical Considerations
Clear Choice includes a responsible-use warning advising compliance with laws.
As a general rule:
-
Laws vary by state/country and sometimes by “intent” (sale, possession, or use to deceive an official test).
-
Employers and testing programs may treat substitution as misconduct even if purchase is legal.
-
In safety-sensitive roles, deception can create serious risk and consequences.
If someone is worried about an upcoming test, the safest path is to follow applicable policies and seek legitimate guidance (for example, understanding medical disclosure rules where appropriate).
Final Verdict
Sub Solution stands out as a premium synthetic urine kit for three reasons:
-
It’s powder-based (mix-on-demand),
-
It’s biocide-free, and
-
It includes a complete set of accessories needed for preparation and temperature checking.
For buyers evaluating synthetic urine products for lawful purposes, Sub Solution is often considered one of the most feature-complete options available—though the price reflects its premium positioning.
