As a competitive Masters bodybuilder at 61 years of age, I don’t have time for “trial and error” supplementation (Do you?), so I rely on the rock-solid gains I get from Primal Muscle products. they provide results I can both feel and see.

Since I started using Primal Muscle supplements about a year and a half ago, I’ve gone from 5’8″ and 215 lbs to 250 lbs, staying solid and strong. My lifts have dramatically increased, and I’m one of the strongest guys at the gym. Lifting has also helped me overcome a tough breakup and depression. I wouldn’t have the energy to hit the gym without Primal Muscle. My ex even thought my supplements were steroids—thank you for these amazing products!

WHY YOUR GAINS STOPPED

You're doing everything mostly right. But your body isn't responding like it used to. It's not your training - it's your cellular biology fighting against you.

Think of your muscle cells like locked vaults. No matter how hard you train, your body's growth signals can't get through. Scientists call it "Receptor Desensitization" - where your muscles become increasingly resistant to growth factors.

Plateaued strength. Stalled gains. Frustrating recovery times. It's not because you're not working hard enough - it's because your muscles became deaf to growth signals.

CYCLOST3: THE ANABOLIC REVOLUTION

CycloST3 is a cutting-edge anabolic agent forged from oligopeptide technology and tracing its roots back to research in NASA and Special Operations. This anabolic juggernaut kicks your body into an anabolic frenzy by blasting testosterone levels and unlocking unparalleled muscle growth and unbelievable recovery.

Key Growth Factors Inside CycloST3:

  • IGF-1 & IGF-2 (Insulin-like Growth Factors 1 & 2): These anabolic powerhouses stimulate muscle development, speed up recovery, enhance brain health, and support overall organ function.
  • FGF (Fibroblast Growth Factors): Critical for skeletal muscle growth, they repair nervous system tissue, improve bone density, and regenerate muscles after tough workouts.
  • CTGF (Connective Tissue Growth Factors): Fortify tendons, ligaments, and connective tissue to withstand heavy lifting and repetitive stress.
  • EGF (Epidermal Growth Factors): Accelerate skin tissue repair for quicker wound healing and a healthier barrier against environmental stressors.

+ Amplified Testosterone with Tribulus Terrestris:

CycloST3 takes testosterone boosting to the next level with Tribulus Terrestris, renowned for its ability to increase natural testosterone production. Combined with CycloST3’s oligopeptide technology, it enhances bioavailability and maximizes testosterone’s muscle-building potential.

+ Added Anti-Estrogen Support with DIM:

CycloST3 doesn’t stop at testosterone optimization. It includes DIM (Diindolylmethane), a natural compound that helps balance estrogen levels by promoting healthy estrogen metabolism. By reducing excess estrogen, DIM creates an environment where testosterone can thrive, leading to improved muscle growth, fat loss, and enhanced overall performance. CycloST3 is your ultimate weapon for building muscle, cutting fat and getting strong as hell!

WHAT BEING ON CYCLOST3 FEELS LIKE

It happens during a regular chest workout.

Something's different. That deep chest pump you haven't felt in years is back. Your shoulders are on fire – the good kind of burn that reminds you of your early lifting days.

Between sets, you notice it in the mirror. Your delts look more capped. There's new thickness in your ‘stubborn’ upper chest.

This isn't water weight or some temporary pump. This is your muscles remembering how to grow again. How to respond to training like they did before they went to sleep.

You’ve probably never experienced anything like this… It’s mind blowing!

Oligopeptides

Our Oligopeptide technology is a natural extract derived from chicken embryos, rich in oligopeptides and growth factors like IGF-1 and IGF-2. These bioactive components play a role in cellular repair, hormone regulation, and overall recovery. By supporting anabolic processes, Oligopeptides may promote faster muscle recovery and enhance strength and endurance. It is also believed to aid in optimizing testosterone levels and improving sleep quality, both of which are critical for muscle growth, fat loss, and athletic performance. Additionally, Oligopeptides have been reported to support fat metabolism, contributing to a leaner physique while enhancing overall energy levels and recovery efficiency.

Tribulus Terrestris

Tribulus, or Tribulus Terrestris, is an herb rich in saponins, particularly protodioscin, which is believed to help naturally increase testosterone levels. This can lead to improved muscle strength, endurance, and recovery post-exercise. Tribulus is often used to enhance lean muscle growth and boost overall athletic performance, making it a popular choice for those aiming to increase muscle mass and improve physical resilience.

Choline Bitartrate

Choline Bitartrate is a compound that supports brain function, nerve signaling, and fat metabolism. As a precursor to acetylcholine, a neurotransmitter involved in muscle control and focus, it enhances mind-muscle connection during workouts, leading to better performance. Choline also plays a role in breaking down fats for energy, supporting fat loss and endurance. Additionally, it may help reduce muscle fatigue and improve recovery, making it a valuable supplement for athletes and fitness enthusiasts.

DIM (Diindolylmethane)

DIM (Diindolylmethane) is a naturally occurring compound derived from cruciferous vegetables like broccoli and kale. It supports hormone balance by promoting the metabolism of estrogen into more favorable forms, which can enhance testosterone levels. This balance is beneficial for muscle growth, fat loss, and overall performance. DIM also has antioxidant properties, helping to reduce inflammation and improve recovery after intense workouts. Its ability to regulate hormones makes it particularly useful for athletes seeking to optimize strength, endurance, and body composition.

Frequently Asked Questions

What’s in CycloST3?
Supplement facts label displaying serving size, proprietary formula, and ingredient details.
How do I take CycloST3?

Directions: Start with 1-2 capsules to assess tolerance, then take 2-4 capsules per day, preferably in two doses -1 dose in the morning and 1 dose in the early afternoon.

How much should I order?

When it comes to CycloST3, consistency is the key to unlocking its full potential. While you may start noticing improvements within the first few weeks, the most impressive and lasting results come from sustained use.

We strongly recommend committing to a cycle of at least 3-6 months for optimal results.

Here’s why:

Hormonal Optimization: It takes time for your body to fully respond to CycloST3's powerful ingredients and reach peak hormonal balance.

Avoid Interruptions: Longer cycles ensure you don't run out at a critical moment in your transformation journey.

For these reasons, we recommend ordering at least a 3-month supply to start. Many of our most successful customers choose the 6-month option to lock in the best value and set themselves up for truly transformative results.

Remember, Rome wasn't built in a day, and neither is your ideal physique. Give CycloST3 the time it needs to work its magic, and you'll be amazed at what you can achieve.

Is CycloST3 safe?

Absolutely. CycloST3 is designed with your safety as our top priority. We use only natural, scientifically-backed ingredients and manufacture in an FDA-registered, GMP-compliant facility. Each batch undergoes rigorous third-party testing for purity and potency. While safe for healthy adult males when used as directed, we always recommend consulting your healthcare provider before starting any new supplement regimen, especially if you have pre-existing conditions or are taking medications. With CycloST3, you're choosing a product that prioritizes both your health and your results.

Who is CycloST3 for?

CycloST3 is specifically formulated for adult men who are serious about maximizing their physical and mental performance. It's ideal for those looking to boost testosterone levels naturally, increase muscle mass, enhance strength, improve libido, and optimize overall vitality. Whether you're an athlete, bodybuilder, fitness enthusiast, or simply a man wanting to feel his best, CycloST3 is designed to support your goals.

Do I need to cycle CycloST3?

While CycloST3 is designed for continuous use, we recommend taking a short break between bottles to maintain its effectiveness. This brief pause allows your body to reset, potentially enhancing the supplement's impact when you resume. A typical cycle might involve using CycloST3 for 8-12 weeks, followed by a 2-week break. This cycling approach can help prevent tolerance build-up and ensure you continue to experience optimal results. However, individual needs may vary, so feel free to consult with our fitness advisors for personalized cycling recommendations based on your specific goals and body response.

Do I need a doctor’s prescription?

No, you CURRENTLY don't need a doctor's prescription to purchase or use CycloST3, but as with anything in life, things can change. This market is always changing, so get it while you can!

How soon can I expect results?

Many users report feeling initial effects of CycloST3 within the first few weeks, such as increased energy and improved mood. However, more substantial results typically become noticeable after 4-6 weeks of consistent use. This includes enhanced muscle growth, improved strength, and increased libido. Keep in mind that individual results can vary based on factors like diet, exercise routine, and overall health. For optimal results, we recommend using CycloST3 consistently for at least 3 months, combined with a proper diet and regular exercise regimen. Remember, transforming your body takes time and dedication, but CycloST3 is designed to accelerate your progress.

Can I take CycloST3 with other medications?

While we have not received reports of specific issues, it's always best to exercise caution when combining supplements with medication. We strongly recommend consulting with your doctor or healthcare provider before adding CycloST3 to your regimen if you're currently taking any medications.

Can I take CycloST3 if I have a medical condition?

If you have a medical condition, we strongly advise consulting with your doctor before starting CycloST3. While we haven't received reports of specific issues, everyone's health situation is unique. Your healthcare provider can evaluate whether CycloST3 is appropriate for you based on your individual medical history and current condition.

What if I am not happy with the results I get?

At Primal Muscle, we stand behind the quality and effectiveness of our products. However, we understand that individual results can vary. If you're not completely satisfied with your results, we offer a 100% money-back guarantee. Simply contact a Fitness Advisor and we’ll get you taken care of.

How soon can I expect my package to arrive?

Your CycloST3 order will typically arrive within 4-6 business days after purchase. We process orders promptly and use reliable shipping methods to ensure your package reaches you as quickly as possible. Delivery times may vary slightly depending on your location and current shipping conditions.

Yes, your credit card information is completely safe when you purchase CycloST3. We use Shopify, a leading e-commerce platform known for its robust security measures, to process all our transactions. Shopify employs industry-standard SSL (Secure Socket Layer) encryption to protect your sensitive data during transmission. Additionally, we do not store your credit card information on our servers.
