Transparent Labs BULK Ingredients

Transparent Labs BULK Pre-Workout ingredients include citrulline malate 2:1 (6000 mg), taurine (1300 mg), beta-alanine (4000 mg), branched-chain amino acids (BCAA) 2:1:1 (4000 mg),  L-tyrosine (1000 mg), BetaPure Betaine Anhydrous (2500 mg),  Astragin (25 mg), AlphaSize Alpha-GPC (300 mg), caffeine anhydrous (180 mg), theobromine (50 mg), L-theanine (360 mg), and Infinergy (30 mg).   The characteristic features and benefits of each of these ingredients are as follows.

Multi-Gi 5 Ingredients


Beta-alanine supplementation enhances the levels of cellular carnosine that are otherwise depleting as a person performs intense exercise. Adequate pre-workout supplementation (4000 mg in the Transparent Labs BULK Pre-Workout supplements) helps delay the development of neuromuscular fatigue, increasing muscle strength, promoting healthy protein formation, improving muscle endurance, decreasing fat, and increasing lean muscle mass.

BetaPure Betaine Anhydrous

Supplementation with betaine helps stimulate muscle growth response, which does not depend on testosterone levels. Betaine supplementation is useful for reducing muscle fatigue, increasing volume and repetitions in exercises, and enhancing the replenishment of phosphocreatine. The supplements do not contain creatine since the simultaneous administration of caffeine may hinder the absorption of creatine by the body.

BCAA (Branched Chain Amino Acids)

This ingredient refers to a collection of leucine, isoleucine, and valine in a ratio of 2:1:1. Leucine is an anabolic amino acid that promotes muscle protein synthesis, increases muscle strength, and preserves lean muscle mass, and prevents the degradation of muscles. Isoleucine has anti-catabolism properties that enable it to support muscle growth and promote energy metabolism in workouts. Valine reduces the retention of tryptophan in the brain, increasing endurance and energy levels.


Astragin is an extract derived from the two adaptogenic herbs – Panax notoginseng and Astragalus membranaceus, which are well-known in Chinese medicine. This extract and the relevant components increase intestinal permeability, promoting selective absorption of certain biomolecules.

Caffeine Anhydrous

Transparent Labs BULK Pre-Workout supplements contain moderate doses of caffeine, which does not have interactions with the physiological thermoregulatory mechanisms. Caffeine reduces efforts, promotes investing in efforts, and increases repetitions in exercise to failure.


Taurine is an important component of pre-workout supplementation. This amino acid has a competitive interaction with beta-alanine, hence, supplementation with only beta-alanine may lead to taurine deficiency. Taurine can also be used along with BCAAs, which helps in reducing muscle soreness.


Infinergy or dicaffeine malate is a caffeine salt of malic acid. This increases the duration of caffeine’s ergogenic effects. This component prevents crashing and jitters, as observed in the consumption of regular caffeine. It also induces long-lasting and smooth improvement in the mental performance of the user.


L-theanine has several advantages for athletes when used in combination with caffeine. The health benefits of this amino acid include a reduction in stress, relaxation without influencing energy levels and attention, an increase in memory, reaction time, and attention, and a reduction in jitters usually experienced by individuals who are caffeine insensitive.


An acetylated form of L-tyrosine, this component reduces stress, increases focus and endurance, improves performance and memory in stressing conditions, and counteracts hypothyroid-related conditions in extensive exercise.

Citrulline Malate

Citrulline malate holds immense significance in the effectiveness of pre-workout supplements. This compound exhibits better absorption and leads to higher levels of plasma arginine as compared to L-arginine. Citrulline malate is accredited with improvement in muscle endurance, strength, and aerobic performance. It increases nitric oxide levels far more effectively than L-arginine supplementation.


Theobromine is present in cocoa beans. The functions of this primary alkaloid are compensatory to the functions of caffeine. It functions as a central nervous system stimulant as well as an inhibitor of phosphodiesterase.

AlphaSize Alpha-GPC

Alpha size is a bioavailable source of choline, which is utilized by the body in the synthesis of acetylcholine and phosphatidylcholine. Alpha-glycerylphosphorylcholine (GPC) enhances both mental and physical performance, particularly in combination with caffeine. This compound also exhibits ergogenic and nootropic properties.
