What is Cambridge Research S-4?

Cambridge Research S-4 is a highly versatile and exciting SARM that is able to selectively generate anabolic activity in the human body while increasing the oxidization of fatty tissues.

Initially developed in order to combat conditions such as Osteoporosis or as prevention for muscle wastage, S4 is one of the most researched SARMs at present. However, it has recently been shown to yield surprising results in clinical trials showing a significant increase in muscle mass and calcium production for increased bone density in a very selective manner.

S-4 is described as an Androgen Receptor (AR) agonist. This means that it has a significant affinity/potency for binding to the AR in order to stimulate the production of anabolic genes that benefit muscle growth.

Andarine has been through human trials but no studies were published. There is some limited information which suggests that S-4 was described as the ideal SARM due to its single-day dosing, complete oral bioavailability and significant anabolic effects.

Results to Expect From Cambridge Research S-4

Studies show that individuals were able to put on 3lbs of muscle tissue while in a calorie deficit! The selective generation ability of S4 also means it does not cause liver damage or gynecomastia – both common amongst SARMs users.

Added to this, it shows 0% chance of aromatization in the period post-cycle, thus mitigating against increases in feminine characteristics. If you are looking for a SARM that can bring unrivalled aesthetic improvements, Andar1ne is one you sure don’t want to miss out on!

Andarine (S4) Side Effects

S-4 can induce negative ocular conditions (yellow vision and light sensitivity) in some research subjects, usually at higher doses. To avoid this it is recommended to administer this compound on a 5 day on, 2 days off protocol and no more than 50mg per day.

  • 0% chance of aromatization
  • Larger increases in muscle mass than DHT
  • An ability to be used by females without excessive masculine features
  • No heart enlargement or damage to organs
  • No diminishing of testosterone during the post-cycle period

The best way to minimise the risks of any side effects is to get informed about how to use Andarine. This includes how much (dosages), how often (should you split the dose), and for how long (cycle length).

When to Use Cambridge Research S-4

Cambridge Research S-4 can be used in both cutting and bulking phases.

For dieting, it can grant muscular gains even while in a prolonged calorie deficit, promoting improved vascularity and a ‘harder’ appearance. While for bulking, it can supercharge your muscle development to optimise your training and diet to get exceptional results.

Cambridge Research S-4 really shows its efficacy during cutting phases, with users able to still put on mass despite being in a calorie deficit thus exhibiting similar, if not better, effects than steroids such as Anavar. However, it can also provide a major boost while in a bulking phase, to truly accelerate muscle gains while mitigating fat gain.

How to Use Cambridge Research S-4

Both males and females can use Cambridge Research S-4, as it is both non-aromatizing (for men) and does not cause excessively masculine features in female users.

Carry out research with 50mg per day split into 25mg am and 25mg pm. Recommended research length is 8-12 weeks.

  • No bloating or fluid retention

WHAT IS ENHANCED ATHLETE S-23?

Enhanced Athlete S-23 is an orally active nonsteroidal SARM that has a very high binding affinity to androgen receptors, making it one of the strongest SARMs. Research shows that the main effects of S-23 are increased muscle mass, decreased fat mass, and a decrease in the size of the prostate. A safer alternative to anabolic steroids, S-23 is extremely effective for burning stubborn body fat. Considered by many as a powerful version of S-4 (Andarine), S-23 is one of the best performance-enhancing drugs to harden muscle for a dry, grainy look.

WHAT RESULTS TO EXPECT FROM ENHANCED ATHLETE S-23

Users of Enhanced Athlete S-23 have reported massive improvements in the levels of lean muscle mass, strength, endurance, and sense of well-being. Many online reviews on eminent bodybuilding and SARMs forums have also suggested that S-23 is a far better option than S-4 when it comes to losing abdominal and visceral fat. In one study, results show that S-23 has the ability to reduce body fat and average body weight.

HOW TO USE ENHANCED ATHLETE S-23

Enhanced Athlete S-23 is best used in cycles of 6-12 weeks although though this can differ according to individual preferences and cycle requirements. 20-30mg every day, preferably 30-40 minutes before workouts and after meals. The half-life of S-23 is around 12 hours and therefore twice a day dosing is fine (two equal split doses of 10-15mg each for male users and 2.5-5mg each for female users: once in the morning and once in the evening) dosing is fine. S-23 is a versatile compound that can be stacked with other SARMs, or with MK-677 for enhanced results. Stack Enhanced Athlete S-23 with Cardarine and SR-9009 for minimising fat-gain on a bulk, or maximising fat loss during a cut.

DOES ENHANCED ATHLETE S-23 CAUSE WATER RETENTION?

Enhanced Athlete S-23 doesn’t lead to any bloating or water retention and therefore it’s the ideal SARM of choice during a cutting/dieting phase or when you prefer to enhance dry gains, vascularity and more muscle definition.

DO I NEED A PCT AFTER ENHANCED ATHLETE S-23?

Enhanced Athlete S-23 is suppressive so a full PCT is highly recommended. Some SARMs can temporarily suppress your natural testosterone levels. It’s important after your cycle that you bring your natural testosterone levels back up to normal levels in order to maintain your results; we recommend a Cycle Support Stack with this product.

WHAT IS ENHANCED ATHLETE CARDARINE?

Enhanced Athlete Cardarine is often referred to as a SARM but technically it is not. Cardarine is a PPAR modulator which has been studied extensively and shown to exhibit potent physiological effects in increasing performance for athletes. Cardarine is most notably effective in boosting muscle endurance enabling users to massively increase the number of reps they can perform as well as improving cardiovascular endurance, something which has made it popular among elite endurance sport athletes.

HOW DOES ENHANCED ATHLETE CARDARINE WORK?

Cardarine GW 501516 binds to the PPAR-delta nuclear receptors which are mostly in your muscles and stimulates some of the genes which govern how your body uses energy. By doing these two things, Cardarine can:
  • Help you burn more body fat – by preventing fatty acid chains from being formed, and therefore stopping your body from storing fat, so your system has to use stood fat for energy
  • Preserve existing muscle mass – when you are in an energy deficit and your body is forced to use fat for fuel, Cardarine can also protect muscle mass from catabolism
  • Faster recovery – Cardarine may increase the amount of oxygen which gets to your muscles, helping you recover from training sessions
Cardarine improves endurance levels and helps athletes to push further, recover faster and greatly improves their cardiovascular health.

RESULTS TO EXPECT WITH ENHANCED ATHLETE CARDARINE

1 FAT BURNING

Cardarine can help you burn more body fat by encouraging your body to use stored fat for fuel, by stimulating glucose, and by activating some of the genes involves in fat burning.

2 BULKING AND CUTTING

Cardarine can be stacked with other SARMs to encourage fat loss, boost training performance, and help you maintain muscle mass when dieting – ideal for cutting and bulking cycles.

3 BRAIN HEALTH

Cardarine can improve blood flow to the brain, protecting brain vessels, boosting the growth of nerve cells, and reducing problematic inflammation.

4 TRAINING ENDURANCE

Cardarine stimulates your body’s use of glucose for fuel, which means you can probably train longer and harder. More training = more muscle gain!

5 MUSCLE GROWTH

Cardarine activates the PPAR-delta which boosts muscle fibres, gives you increased energy and means you can train for longer too.

6 HEART HEALTH

Cardarine may have a protective benefit for your blood vessels, reducing oxidative damage and plaque build-up, and increasing your levels of nitric oxide.

HOW TO USE ENHANCED ATHLETE CARDARINE

Cardarine is kind of an all-rounder, you can use it for cutting or bulking cycles. It has a half-life of 16 hours, so you will need to split your daily total dose into two doses. Start with 10mg/day (5mg twice per day), ideally with one dose 2-3 hours before you train. Run Cardarine for a maximum of 12 weeks, followed by a 6 week off-cycle break. Cardarine can be stacked with most other compounds. It mitigates fat-gain during bulking cycles, increases fat-loss during cutting cycles, and enhances endurance and performance all-round. Here are the most popular SARMs stacks:

DOES ENHANCED ATHLETE CARDARINE HAVE SIDE-EFFECTS?

Like any compound, you should be sensible about using Enhanced Athlete Cardarine. This includes looking out for side effects. Cardarine won’t suppress your natural hormone levels. It is always recommended to start off with lower doses and assess response and adaptation. If there is anything we haven’t covered in this Cardarine Review, see our Guide to Cardarine for more information.

  • No hepatoxicity so safe to stack with another SARM or prohormone
  • Faster muscle growth than any natural test booster
  • Much improved recovery

What Results to Expect With Narrows Labs YK-11

Positive reviews of Narrows Labs YK-11 report that it greatly increases muscle mass and its effects are seen in as little as a week. Some users report no side effects at all or very mild testosterone suppression. However, these claims are clouded by the fact that people use different dosages, cycle lengths, or stack YK11 with other SARMs. Bodybuilders have experimented with YK11 in both bulking and cutting. Allegedly, YK11 is useful in bulking because it builds a lot of lean muscle in a short amount of time. Others have taken advantage of YK11’s ability to burn fat and harden muscles by using it in cutting cycles.

YK-11 Side Effects

YK11 may potentially be toxic to the liver. However, some users reported doing blood tests during cycles of YK11 and initial results didn’t indicate abnormal markers of liver damage. We would recommend using liver support throughout your cycle. Mild testosterone suppression has been reported. To be on the safe side, almost all bodybuilding resources recommend post-cycle therapy (PCT) after a cycle of YK11. Common PCTs include Nolvadex (tamoxifen) and Clomid (clomifene). Other reported side effects include:
  • Increased aggression
  • Joint pain
  • Low energy
  • Mild testosterone suppression
  • Hair loss
  • Mild acne

Muscle Building with YK-11

YK11 boosts the growth of muscle cells by increasing follistatin levels, according to cell-based studies. Follistatin suppresses myostatin, a protein that normally stops excessive muscle growth.  Anecdotal evidence from bodybuilders suggests it is effective at increasing muscle size. Users report lean muscle gains of up to 15 lbs and a decrease in body fat after a single cycle.

Is Narrows Labs YK-11 a SARM or a Steroid?

YK11 is a steroid made by directly altering the chemical structure of DHT. In contrast, all other SARMs have a nonsteroidal structure. YK11 and SARMs work differently in the body and may have different side effects. YK-11 has a very unique structure which shares more in common with steroids than it does with SARMs. Because this class of drugs is so new, no established naming convention exists. Based on its activity and chemical structure, it may be more appropriate to call YK11 a synthetic steroid rather than a SARM.

How to Use Narrows Labs YK-11

Narrows Labs YK-11 should be cycled for periods of 4-8 weeks followed by a PCT as you would do with a prohormone cycle. Users of YK-11 should expect an easier recovery though compared to a prohormone cycle. This is a supplement that is strictly for males aged 21+ with a solid background of training who are now seeking to embark to a higher level of muscle mass and strength.

Narrows Labs YK-11 Dosage

The most common dosage is 10-15mg/day. Users have also seen good effects at 5mg, which is a recommended starting dose for new users. Some people report doses as high as 30 mg with no side effects. The half-life of YK-11 is 6-10 hours so the ideal dosing strategy is to split each daily dose into two. By taking two doses a day, YK11 levels should remain more stable, although there is no clinical evidence to confirm this.

Stacking YK-11

Stacking YK11 with other SARMs can lead to superior results. Users report stacking YK11 with LGD-4033 or RAD-140 and using a lower dose of YK11, typically 5-10 mg per day.
