Gcp Proprietary Blend
Also known as: Gcp Proprietary Blend, LN18178, Tesnor®, Proprietary Blend of Punica granatum rind and Theobroma cacao seed extracts
Overview
The Gcp Proprietary Blend refers to a specific proprietary mixture of ingredients, often including extracts from *Punica granatum* (pomegranate) rind and *Theobroma cacao* (cocoa) seeds, exemplified by the patented ingredient Tesnor® (LN18178). As a proprietary blend, its exact composition and the precise quantities of individual ingredients are typically not disclosed on product labels, which is a common practice in the dietary supplement industry. This blend is primarily marketed as a dietary supplement aimed at enhancing serum testosterone levels, improving muscle strength, reducing symptoms associated with aging in males (AMS), and alleviating stress. While the concept of proprietary blends faces challenges regarding transparency and regulatory oversight, at least one randomized controlled trial has shown promising results for a specific formulation (LN18178) in healthy middle-aged men, indicating its potential in modulating hormonal pathways and improving physical and psychological well-being.
Benefits
The Gcp Proprietary Blend, specifically the LN18178 formulation, has demonstrated several benefits in healthy middle-aged men. A 56-day randomized controlled trial involving 120 participants showed that daily supplementation with 200 mg or 400 mg significantly reduced Aging Male Symptoms (AMS) scores, increased both free and total serum testosterone levels, improved hand-grip strength, and lowered perceived stress scores compared to a placebo group (p < 0.05). Additionally, participants reported improvements in psychological and sexual well-being. These benefits were observed in men aged 36-55 experiencing aging male symptoms. While the study reported statistically significant improvements, specific effect size metrics were not detailed. The evidence for these benefits is derived from a single, well-conducted randomized controlled trial, suggesting a moderate level of evidence for this specific blend in the studied population.
How it works
The Gcp Proprietary Blend is believed to exert its effects primarily by modulating hormonal pathways within the body. Its components likely interact to increase serum testosterone levels, and potentially dihydrotestosterone (DHT), while simultaneously working to reduce levels of stress hormones like cortisol and female hormones such as estradiol. This hormonal rebalancing contributes to improved muscle strength and reduced perceived stress. The mechanism involves the modulation of the endocrine system, particularly influencing the hypothalamic-pituitary-gonadal (HPG) axis, which regulates hormone production. While specific molecular targets are not explicitly detailed, the blend is presumed to act via pathways related to androgen receptors and stress hormone regulation, leading to its observed physiological benefits.
Side effects
The Gcp Proprietary Blend, specifically the LN18178 formulation, has shown a favorable safety profile in the available research. In a 56-day randomized controlled trial, the blend was well tolerated, with no significant adverse effects reported at doses of 200 mg and 400 mg daily. Blood chemistry and urine analyses conducted during the study revealed no safety concerns, indicating that it did not negatively impact liver, kidney, or other vital organ functions. No common (>5%), uncommon (1-5%), or rare (<1%) side effects were reported. Data regarding drug interactions are currently unavailable, and no specific contraindications have been identified. It is important to note that the safety data is limited to healthy middle-aged men, and its safety profile in other populations, such as women, younger individuals, or those with pre-existing medical conditions, is unknown. Therefore, caution is advised for individuals outside the studied demographic.
Dosage
For the Gcp Proprietary Blend, specifically the LN18178 formulation, the minimum effective dose identified in research is 200 mg daily. An optimal dosage range of 200–400 mg daily has demonstrated efficacy in improving testosterone levels, muscle strength, and reducing stress and aging male symptoms. The maximum safe dose has not been established beyond 400 mg in the cited study. For best results, continuous daily supplementation for at least 56 days is recommended, as benefits were observed after this duration in the clinical trial. The blend is typically consumed in oral forms such as capsules or tablets. Specific absorption factors or required cofactors for optimal efficacy have not been detailed in the available research. Users should adhere to the recommended dosages and consult a healthcare professional before exceeding them or if they have underlying health conditions.
FAQs
Is the exact composition of Gcp Proprietary Blend known?
No, proprietary blends like Gcp do not typically disclose the precise amounts of individual ingredients on their labels, which limits transparency for consumers and researchers.
Are proprietary blends safe?
Safety varies by specific blend. While LN18178, a specific Gcp blend, showed good safety in a controlled trial, the lack of transparency for other blends makes generalization difficult and raises concerns.
How soon can benefits be expected from Gcp Proprietary Blend?
In the cited research, significant benefits related to testosterone levels, muscle strength, and stress reduction were observed after 56 days of continuous daily supplementation.
Can proprietary blends be trusted?
The lack of ingredient transparency in proprietary blends complicates trust and assessment. While some blends may be effective, limited regulatory oversight can raise concerns about consistency and safety.
