Blackstone Labs | BSL CARNITRIM | 60 Tablets

Blackstone Labs CARNITRIM is a fully disclosed, stimulant-free weight-management formula built around one central idea: use multiple carnitine forms to support fatty acid transport and cellular energy metabolism, then reinforce that base with EGCG from green tea and B-vitamin support. This is not a crash-inducing thermogenic. It is a lighter, more metabolic-support-oriented formula designed for people who want a cleaner approach to cutting, cardio, or appetite-conscious phases without relying on heavy stimulants.

The core of the formula is a three-form carnitine matrix. Carniplex™ carnitine silicate provides 250 mg per serving. Carnitine’s primary role is shuttling long-chain fatty acids into the mitochondria, where they can be oxidized for energy. That pathway is the physiological reason carnitine products are positioned for energy and fat-loss support. Carnitine silicate is included as a branded form, which signals a focus on differentiated delivery rather than generic bulk material. At 250 mg, this is below the 1-3 g daily total carnitine intake commonly discussed in fat oxidation and exercise literature, so it is better viewed as part of a blended carnitine strategy than a standalone clinical-dose centerpiece.

Propionyl L-Carnitine HCl is included at 250 mg. This form is often discussed for circulation and energy-related applications because the propionyl group changes how the molecule is utilized in tissue metabolism. In practical terms, it complements the broader mitochondrial transport role of the other carnitines and helps make this formula feel more rounded than a single-source carnitine product. Again, the dose is modest relative to common standalone research ranges, but it contributes to the total system.

CarniPure® L-Carnitine L-Tartrate provides another 250 mg. CarniPure® is the most recognizable trademark in the carnitine category and one of the strongest quality signals on the label. L-carnitine L-tartrate is widely used in sports nutrition for exercise recovery and performance support, particularly in formulas aimed at training populations. At 250 mg, it is below the more robust dosing used in sports-performance studies, but the use of CarniPure® is still a meaningful quality advantage over unnamed raw material.

EGCG is included at 100 mg. Epigallocatechin gallate is the marquee catechin in green tea and is commonly used in non-stim fat-burner formulas because it supports thermogenesis and fat metabolism through catecholamine-related pathways. It also adds antioxidant support to a formula otherwise centered on nutrient transport. The dose is conservative compared with more aggressive green tea extracts, but it fits the product’s stim-free, tolerance-friendly positioning.

Niacin at 50 mg and vitamin B6 at 10 mg round out the formula. Niacin is a precursor to NAD and NADP, coenzymes essential to energy production and redox reactions. At this dose, it is not being used like pharmacologic high-dose niacin from lipid-management research; it is here as metabolic support and may cause a mild flush in sensitive users. Vitamin B6 supports amino acid metabolism and neurotransmitter synthesis, giving the formula basic cofactor support rather than headline effects.

As a system, CARNITRIM combines transport support from three carnitines, thermogenic assistance from EGCG, and foundational vitamin support for energy metabolism. The major positive is full-label transparency: no proprietary blend, exact milligram disclosure, and trademarked carnitine forms. The limitation is equally clear: this is a mild formula, and several actives are below the stronger dosing ranges seen in standalone ingredient research. On day 1, expect very little stimulant-like sensation, possibly a mild niacin flush, and no crash. Over 2-4 weeks of consistent use, the realistic expectation is cleaner support for a cut, cardio block, or body-composition phase rather than a dramatic feel-it transformation.
