AnaFuse by Vital Alchemy

Get ready to ignite your anabolic furnace with AnaFuse, the latest addition to the Vital Alchemy family of muscle-building supplements. Say goodbye to traditional bulking methods and hello to a new era of muscle growth with AnaFuse, the first-ever Dual Agent Bulking Stack.

This groundbreaking supplement combines a flawless fusion of recently discovered anabolics to create muscle-building synergy, delivering serious lean, hard muscle mass. AnaFuse is designed to help you add muscle and keep it without the nasty side effects associated with hardcore anabolics. Experience the power of a complete formula that includes all the necessary factors for muscle growth, all in one convenient package.

In Anafuse, the ingredients work synergistically to push your muscles beyond their limits by improving your body's resistance to muscle fatigue, leading to significant increases in muscle endurance and exercise capacity.

This supplement promotes mass gains by inhibiting and reducing Myostatin, a protein that restricts your body's genetic potential for muscle growth. It accelerates your body's muscle repair process, resulting in the development of new, stronger, and denser muscle tissue.

During workouts, Anafuse floods your muscles with blood, saturating them with essential nutrients for muscle growth and creating intense muscle pumps. Furthermore, it enhances muscle recovery and reduces soreness, allowing you to train harder. Get ready to elevate your training intensity!

Key Ingredients of AnaFuse

Epicatechin, a flavanol present in plants like green tea and cocoa, acts as a potent antioxidant that reduces Myostatin levels. Myostatin is a key factor that limits muscle growth by suppressing its development. Lowering Myostatin enables muscle growth beyond genetic potential.

Ajuga turkestanica, also known as Turkesterone, is a natural compound found in plants and insects. It is believed to be one of the potent natural supplements for fat loss, muscle building, improving focus, and enhancing muscle recovery.

HICA: It is a metabolite of the amino acid leucine, enhances protein synthesis, and reduces muscle protein breakdown. It achieves this by counteracting catabolic muscle-wasting products produced during intense training, supporting muscle mass and strength gains, and speeding up muscle recovery.

Eriobotrya Japonica: Also known as the EJ plant, it contains a variety of natural anabolic ingredients that are beneficial for building muscle, burning fat, and increasing athletic performance.

Vitamin D3 is crucial for muscle health. Insufficient levels of Vitamin D3 can result in reduced protein synthesis, weakened strength, and muscle wasting. Moreover, deficiencies in Vitamin D3 contribute to the accumulation of fat in muscles, negatively impacting strength and power.

Quercetin, a flavanol present in fruits, vegetables, leaves, and grains, is often used to promote respiratory health and cardiovascular well-being and maintain balanced blood pressure.

Key Benefits of AnaFuse

  • It supports increased muscle mass gain.
  • It helps reduce body fat.
  • It increased muscle endurance.
  • It helps increase strength.
  • It improves muscle pumps.

Colossal Muscle by Hard Rock Supplements

Are you looking for a natural method to enhance your body's muscle mass and strength? Look no further than Colossal Muscle by Rock Hard Supplements, the latest all-natural anabolic supplement that promises two exciting and effective ingredients. 

One of these ingredients was tested in a 10-week study and showed significant increases in muscle mass and strength among the participants. So far, no other supplement company has combined these two ingredients with these doses. With Colossal Muscle, you will experience muscle growth, increased strength, improved endurance, and enhanced protein synthesis.

Key Ingredients of Colossal Muscle

20-Hydroxyecdysone: 20-Hydroxyecdysone, commonly known as Ecdysterone, is a well-researched ingredient that demonstrated substantial boosts in muscle mass and strength in participants of the 'Ecdysteroids as Non-Conventional Anabolic Agent Study' conducted in 2019.

3- AlphaBulk by Olympus Labs

AlphaBulk by Olympus Labs

AlphaBulk is a unique and potent supplement that delivers unrivaled strong lean mass gains and simultaneous fat burning. ALPHABULK features a cutting-edge anabolic agent, α-Cedrene, at a clinically effective dosage level, known for significantly boosting skeletal muscle mass and strength while promoting fat loss. 

Alongside α-Cedrene, another key addition is α-Ionone, in its most potent liquid form, building on its success in K1NGS PCT. This combination delivers a clinically validated dosage to intensify muscle protein synthesis while acting as a potent anti-catabolic and lipotropic agent. AlphaBulk incorporates Liquigel capsules, a novel and revolutionary technology, to guarantee maximum benefits.

Key Ingredients of AlphaBulk

α-Cedrene, sourced from cedarwood oil extracted from various conifer species like pine or cypress families, is a widely used ingredient in cosmetics and food additives. Recent studies have identified α-Cedrene as a potent agonist of the OR subtype OR10J5, leading to significant increases in cAMP in target tissues like skeletal muscle and fat cells. This research suggests that α-Cedrene may be a promising agent for enhancing skeletal muscle mass and strength.

α-Ionone, belonging to the family of compounds called rose ketones, is an aromatic compound present in small quantities in various essential oils and fruits like raspberries. Recent studies indicate that α-ionone serves as a potent stimulator of myogenesis and acts as an anti-atrophic agent for skeletal muscles.

Tectochrysin PhytoFUSE: Extracted from the roots of Black Ginger, it facilitates increased protein synthesis and nitrogen retention, fostering an array of anabolic effects such as heightened muscle endurance, faster muscle recovery, and the promotion of lean muscle mass through enhanced skeletal muscle hypertrophy.

Moreover, Tectochrysin has demonstrated support for skeletal muscle ATP production, glucose uptake in skeletal muscle, and overall exercise performance. PhytoFUSE, a distinctive delivery technology, enhances the bioavailability and absorption of various compound classes, including Methoxy Flavones.

Urolithin B: Studies indicate that incorporating ellagitannins into the diet helps alleviate muscle damage from intense exercise and shields muscles from stresses induced by a high-fat diet. Clinical research conducted on mice with Urolithin B revealed its capacity to enhance the growth and differentiation of myotubes by increasing protein synthesis. 

Additionally, it demonstrated the ability to inhibit the ubiquitin-proteasome pathway (UPP), which is the primary mechanism for protein catabolism. Additionally, Urolithin B induced muscle hypertrophy and mitigated muscle atrophy.

Key Benefits of AlphaBulk

“I recently purchased Alpha Bulk two weeks ago and all I can say is WOW!!!! The only up downside about the pills are the taste, I’m taking 3 pills daily on an empty stomach. I like to train that way. They give me more endurance and can get out an extra rep or two before failure. No size yet, I’m only two weeks in. I ordered 2 bottles to run so I’m hoping to get a bit vascular full size.”

-LaMichael W.

5-stars.png2 weeks in and absolutely loving the gains

“About 3 weeks in so far and I'm already noticing more fullness to my muscles, better pumps, more vascularity, and improvements in strength. This stuff works incredibly well for being completely natural. Its almost like running a cycle of PHs but without any of the euphoric effects that the PHs provide. It just simply WORKS. No side effects whatsoever so far. Another positive that I noticed is that I don't feel as sore or achy the day after hard training sessions. Currently taking 4 capsules per day on training days and 2 caps a day on rest days just to stretch out my supply. I'll definitely be using this again in the near future. Very impressed.”

-Trevor G.

One week

“It’s only been a week, but I’m being asked to do this review. No issues or concerns at this time but one positive today’s work out was different, felt stronger, focused and energized.

I would love to send second week up date if days like this continue. The 4 stars is just because of the short time to review.”

-Ramon G.
