Where your batch is tested
What every test catches — and why it matters
Two independent labs. Different specialties. Same goal: no surprises in your stick pack.
01 โ Informed Sport (LGC)
Banned substance screen
Banned substance screen
250+ compounds tested per batch against the WADA Prohibited List, NCAA banned substances, and CrossFit’s drug-testing policy. Catches stimulants, anabolic agents, beta-blockers, masking agents, and cross-contamination. Tested at LGC's UKAS-accredited lab (#1187) in the UK.
02 โ Heavy Metals (ARL ICPMS)
Arsenic ยท Cadmium ยท Mercury ยท Lead
Arsenic ยท Cadmium ยท Mercury ยท Lead
Inductively-coupled plasma mass spectrometry — the same method the FDA uses. Each batch is screened against strict specs (under 15 ppm As, under 4 ppm Cd, under 5 ppm Hg, under 5 ppm Pb). Tested at ARL (ISO/IEC 17025:2017, #77504) in Lehi, UT.
03 โ Microbiology (USP/AOAC)
Pathogens & contamination
Pathogens & contamination
USP <2021>, <2022> and AOAC methods for total plate count, coliforms, E. coli, S. aureus, Salmonella, yeast, mold, and Enterobacteriaceae. Same standards used by the supplement industry to confirm a product is safe to consume.
04 โ Identity & Strength
The label tells the truth
The label tells the truth
Identity Test (FT-IR). The lab takes a sample of your batch and runs an infrared scan — like a fingerprint reader for chemistry. The scan creates a unique pattern that gets compared against a master reference. Each batch must match the reference at 90% similarity or higher to pass. This proves nothing got swapped, mislabeled, or contaminated during manufacturing.
Strength Test (Sodium content). The label says 600 mg of sodium per stick pack. The lab literally measures the sodium in each batch using gravimetric analysis. The result has to land between 600–750 mg per serving. No under-dosing, no over-dosing — what you read on the label is what you drink.
The same screening used by elite sport
The Informed Sport program by LGC is the banned-substance screen used by professional sports organizations, Olympic committees, and NCAA programs worldwide to verify supplements as athlete-safe. Every batch of EN passes the same screen — published openly above, batch by batch.
250+ banned substances
The World Anti-Doping Agency maintains the global list of prohibited compounds in elite sport. LGC's Informed Sport screen tests against this list each cycle. EN passes every batch.
Collegiate athlete-safe
The NCAA Banned Substances List overlaps substantially with WADA's prohibited list. Athletes in NCAA programs are responsible for what they consume — Informed Sport certification removes the doubt.
Tested to Olympic-level scope
The IOC adopts the WADA Prohibited List. Olympic athletes routinely select Informed Sport-certified products to avoid inadvertent doping. EN's batch certificates are public and verifiable.
NFL ยท NBA ยท MLB ยท UFC ยท MLS
Professional sports organizations operate their own drug-testing programs, many of which reference WADA-aligned screening. Informed Sport is the same third-party program used by athletes across these leagues to verify supplements.
Note: Engineered Nutrition is not affiliated with, endorsed by, or sponsored by WADA, the NCAA, the IOC, the NFL, NBA, MLB, UFC, MLS, or any other sports governing body or league. The Informed Sport program is operated by LGC Ltd. Every Engineered Nutrition Hydration Drink Mix batch is independently certified by LGC's Informed Sport program; verify any batch at sport.wetestyoutrust.com.
Is EN safe for my sport?
Straight answers on certification, banned substances, and what every batch is tested against.
Is EN safe for NCAA athletes?
Yes. Every batch of EN Hydration Drink Mix is certified through LGC's Informed Sport program — the same third-party banned-substance screening used to verify supplements as compliant with NCAA, WADA, and professional-sport drug-testing standards.
The NCAA holds athletes responsible for what they consume, regardless of source. Informed Sport certification gives NCAA athletes a verified, batch-by-batch record they can show their compliance officer. Find your batch above to see the LGC certificate for the stick pack in your hand.
Will EN trigger a positive on a WADA-style drug test?
No. Each batch is screened by LGC against 250+ compounds on the WADA Prohibited List using the Informed Sport program's nutritional-supplement testing specification. Every batch certificate on this page shows "All compounds: Negative" — the formal result language for no detected banned substances.
If WADA's list changes year-to-year, the next production batch's screening reflects the updated list. The certificate above your specific LOT tells you which version was used.
Is EN compliant with professional sports league drug-testing programs?
Professional sports leagues (NFL, NBA, MLB, UFC, MLS, etc.) operate their own drug-testing programs, with prohibited-substance lists that overlap heavily with WADA's. Each league sets its own policies — Engineered Nutrition is not affiliated with or endorsed by any league.
Informed Sport is the third-party screening program many of these leagues' athletes use to verify supplements as safe. EN's batch-by-batch Informed Sport certification provides the same third-party documentation a pro athlete would look for. Athletes subject to any specific league's testing should confirm with their compliance staff.
What's the difference between Informed Sport and NSF Certified for Sport?
Both are reputable third-party banned-substance certification programs.
Informed Sport is operated by LGC (UK-based, UKAS Accredited Lab #1187) and screens against 250+ compounds aligned with the WADA Prohibited List. It's widely recognized across Olympic, NCAA, and professional sports programs globally.
NSF Certified for Sport is operated by NSF International (US-based) and covers a similar scope with its own prohibited-substance list. It's also recognized by major North American sports organizations.
EN is certified through Informed Sport, with every batch published openly on this page.
How often is EN actually tested?
Every production batch. Not annually. Not by sample. Every batch is tested before a single stick pack ships:
1. Informed Sport screen (LGC) — banned-substance certification, batch-by-batch.
2. Certificate of Analysis (ARL) — heavy metals (ICPMS), 8-test microbiology panel.
3. Identity & strength testing (early production) — FT-IR identity verification, sodium-content strength.
You're looking at all of it above — one card per batch, 10 batches deep, all real numbers.
What exactly is a "banned substance"?
A compound prohibited in elite sport — either because it offers an unfair performance advantage (stimulants, anabolic agents, hormones, beta-blockers, diuretics, masking agents) or because it carries health risk under the conditions athletes use it.
The reference list is the WADA Prohibited List, maintained by the World Anti-Doping Agency and adopted by Olympic, professional, collegiate, and many amateur sports bodies. Informed Sport screens supplements against this list at the laboratory level — flagging any of the 250+ compounds at the parts-per-billion sensitivity threshold an athlete would actually trip on.
Where can I independently verify EN's Informed Sport certification?
On Informed Sport's own website. Search "Engineered Nutrition Hydration Drink Mix" at sport.wetestyoutrust.com — every certified batch is listed publicly.
The LOT number on your stick pack matches a specific entry there, and you can cross-reference it with the certificate linked in the batch card above on this page.

What the technical terms actually mean
The lab reports above use some industry shorthand. Here's what each term means in plain language.
- COA
- Certificate of Analysis. A document a lab produces after testing a specific batch. Lists every test performed, the spec (allowed range), the result, and pass/fail. Required to prove what's actually in a supplement.
- Informed Sport
- A third-party banned-substance certification program run by LGC (a UK-based UKAS-accredited testing lab). Tests supplements against 250+ compounds on the WADA Prohibited List. Used by Olympic, NCAA, and professional sports athletes.
- WADA
- The World Anti-Doping Agency. Maintains the global list of prohibited compounds in elite sport (the "WADA Prohibited List"). Adopted by the IOC, NCAA, and most professional sports leagues' drug-testing programs.
- ICPMS
- Inductively-Coupled Plasma Mass Spectrometry. The lab technique used to detect trace heavy metals (arsenic, cadmium, mercury, lead) in supplements. Sensitive enough to measure parts-per-billion. The same method the FDA uses.
- ppm
- Parts per million. A measurement unit for very small concentrations. EN's heavy-metal limits are under 15 ppm arsenic, under 4 ppm cadmium, under 5 ppm mercury, under 5 ppm lead. We typically test 100× below those limits.
- USP
- The United States Pharmacopeia. Sets quality standards for supplements and pharmaceuticals. Standards referenced on this page include USP <197A> (identity), USP <730> (sodium), USP <2021>/<2022> (microbiology).
- FT-IR
- Fourier-Transform Infrared Spectroscopy. A test that produces a molecular fingerprint of a sample. The lab compares your batch's fingerprint against a reference to confirm it's actually what the label says (no swaps, no contamination).
- cGMP
- Current Good Manufacturing Practice. FDA-mandated standards for supplement manufacturing facilities. Covers cleanliness, batch documentation, ingredient verification, and quality control. Required for all U.S. supplement production.
- ISO/IEC 17025
- The international standard for testing and calibration laboratory competence. When a lab is "17025 accredited" it means an independent body has audited their methods, training, and equipment. EN's heavy-metal testing partner ARL holds this accreditation (lab #77504).
This is what transparency looks like.
Every ingredient on the label. Every dose in the formula. Every batch tested independently and published here. That's it — that's the standard.
