Bottom line: Transparent Labs Body Recomp Fat Burner is a premium caffeine-containing weight-management supplement for people already dieting and training. The formula is more honest than many fat burners, but the expected effect is still support-level, not a replacement for calories, protein, steps, and resistance training.
How We Evaluated Transparent Labs Body Recomp
Last checked: April 2026
For this update, we checked the current Transparent Labs Body Recomp product page, the old FitnessVolt review, ingredient evidence for green tea extract, ForsLean, Capsimax, natural caffeine, and BioPerine, plus competing reviews from BarBend, Total Shape, Consumer Health Digest, Supplements Tested, Fat Burners Digest, and current non-stim fat-burner roundups.
We scored the product for formula transparency, evidence quality, appetite and thermogenesis logic, caffeine usefulness, safety, value, buying convenience, and whether its claims are realistic for readers trying to lose fat.
Quick Verdict
Transparent Labs Body Recomp is best for dieters who want a stimulant-supported fat-burner formula from a transparent supplement brand. The current formula centers on green tea extract, ForsLean, natural caffeine, L-theanine, Capsimax, and BioPerine, which makes more sense than the old ingredient list this page used to cover.
It is not the best fit if you are caffeine-sensitive, training late, using other stimulant products, or expecting a capsule to drive fat loss by itself. We could not confidently verify a clean Amazon listing for the exact Transparent Labs product, so the Buy Now button goes direct and the Amazon links below are clearly labeled alternatives.
What Changed Since Older Reviews
The old FitnessVolt review described a previous PhysiqueSeries-style formula with ingredients such as 5-HTP, L-tyrosine, white willow, cayenne, and synephrine. The current Body Recomp product is cleaner to explain: green tea extract, ForsLean, natural caffeine, L-theanine, Capsimax, and BioPerine.
This matters for ranking and trust. A reader comparing reviews should immediately know whether a page is talking about the current product or an older formula that no longer matches the label.
Who Should Buy It
- Morning dieters: You want caffeine-backed appetite and energy support earlier in the day.
- Transparent-label shoppers: You prefer open dosing and third-party testing visibility.
- People already tracking intake: This is most useful when calories, protein, and training are already handled.
- Users replacing another caffeine source: It can make sense if it replaces, rather than stacks on top of, other stimulants.
Who Should Skip It
- Caffeine-sensitive users: Choose the stim-free Body Recomp version or another non-stim option.
- Late-night trainers: Caffeine can still affect sleep even if you feel tolerant.
- Amazon-only buyers: Use the verified Amazon alternatives below.
- Anyone not in a calorie deficit: A fat burner cannot override the fundamentals.

Current Ingredient Breakdown
Green Tea Leaf Extract
Green tea extract is included for catechins and weight-management support. It is one of the more studied fat-burner ingredients, but the practical effect is still small compared with calorie control and activity.
ForsLean
ForsLean is a branded coleus forskohlii extract. It has body-composition research behind it, but the evidence is not strong enough to view it as a stand-alone fat-loss solution.
Capsimax
Capsimax is a branded capsicum extract. Capsaicin-style ingredients may support thermogenesis or appetite control, but they can also cause warmth, reflux, or stomach discomfort.
Natural Caffeine
Caffeine is the ingredient most users will feel. It can improve energy, focus, and appetite control, but it also raises the risk of jitters, sleep disruption, anxiety, and stimulant stacking if you also use coffee, energy drinks, or pre-workout.
L-Theanine
L-theanine is included to smooth the caffeine experience. It does not make the formula stimulant-free, but it can make the energy feel less sharp for some users.
BioPerine
BioPerine is included as a black pepper extract to support absorption. It can interact with some medications, so this is not a throwaway ingredient for everyone.

Transparent Labs Body Recomp vs. Stim-Free Body Recomp
Choose the regular Body Recomp if you want caffeine and plan to use it earlier in the day. Choose the stim-free Body Recomp if sleep, anxiety, blood pressure, or total caffeine intake are concerns.
Transparent Labs vs. Legion Phoenix
Legion Phoenix is the closest premium-label comparison on Amazon. Transparent Labs wins if you specifically want the current Body Recomp formula and third-party testing visibility from Transparent Labs. Legion wins if Amazon checkout and brand familiarity are more important.
Transparent Labs vs. Jacked Factory NITROSURGE Shred
NITROSURGE Shred is closer to a cutting pre-workout than a capsule fat burner. Pick it if you want training-session energy. Pick Transparent Labs if you want a capsule-based product built for dieting support.
Side Effects and Safety Notes
Possible side effects include jitters, anxiety, reflux, nausea, headaches, fast heart rate, sleep disruption, or medication interactions. Be careful with caffeine stacking, avoid taking it near bedtime, and talk with a clinician if you have cardiovascular, blood pressure, liver, kidney, anxiety, reflux, or medication concerns.
Our Score
Overall score: 4.2 out of 5. Transparent Labs Body Recomp scores well for label transparency, caffeine-backed dieting support, and a cleaner current formula. It loses points because fat-burner effects are modest, caffeine is not for everyone, the exact product is direct-only for us, and cheaper Amazon alternatives exist.
FAQ
Is Transparent Labs Body Recomp worth it?
Yes, if you want a premium caffeine-containing fat-burner supplement and already have a real nutrition plan. It is not worth it if you expect the capsules to replace a calorie deficit.
Does Transparent Labs Body Recomp contain caffeine?
Yes. The regular Body Recomp formula contains natural caffeine. Transparent Labs also sells a stim-free version, so check the label carefully before buying.
Will it burn fat without dieting?
No. It may support energy, appetite, or thermogenesis, but fat loss still requires a consistent calorie deficit.
Is the stim-free version better?
It is better if caffeine affects your sleep, anxiety, blood pressure, or total stimulant intake. The regular version is better if you tolerate caffeine and want more noticeable energy support.
Bottom Line
Transparent Labs Body Recomp Fat Burner is one of the more sensible premium fat-burner products because the current formula is transparent and not overloaded with mystery stimulants. Use it as a small support tool during a structured cut, not as the plan itself.
