Andarine S4 SARM On Reddit

Andarine S4 SARM Introduction

Did you know that recreational anabolic steroids exceed 10 to 100 times the recommended amount for controlled medical treatments? Recent research indicates anabolic steroids have a myriad of side effects with misuse, including:

  • Acne

  • Stunted growth

  • High blood pressure

  • xfKidney damage

  • Infertility

Newer research has focused on SARMs and channeling the effects seen with anabolics without adverse reactions. Andarine S4 is one selective androgen receptor modulator that has the potential for in-depth research and future clinical trials. 

Unfortunately, it has become plagued with mislabeling and manufacturing by companies who don’t follow regulations that ensure its purity. If you have had an interest in purchasing SARMs for research through open-source forums, you may want to think again. 

In our article, we will go over the dangers of purchasing Andarine S4 on open-source forums like Reddit and where to buy high-quality SARMs, so keep reading for more information!

What Are SARMs?

SARMs are selective androgen receptor modulators. They act as agonists or antagonists on androgen receptors throughout the body. 

Research has currently shown that SARMs limit side effects compared to androgens while enhancing anabolic effects.   Research states they are chemically engineered molecules that show possible effects in:

  • Osteoporosis

  • Alzheimer’s

  • Breast cancer

  • Stress urinary incontinence

  • Prostate cancer

  • Benign prostatic hyperplasia

  • Hypogonadism

  • And more

There have been nine recent studies in phase 1 and phase 2 clinical trials that have assessed individual SARMs or combinations for various conditions. Currently, SARMs are not approved for human use outside of controlled and regulated clinical studies. 

This research chemical is only legal for research purposes only. Due to the effects andarine and other SARMs may cause, they are banned by many sport agencies such as the world anti doping agency.

What Is Andarine S4 SARM?

Andarine S4 is a type of selective androgen receptor modulator, SARM and acts similarly to other SARMs products.

It is also sometimes referred to as: GTX-007. Essentially, they are the same chemical, and it is not uncommon for SARMs to be listed under a series of letters and numbers such as andarine S4.

Andarine attaches to selective androgen receptors, stimulating anabolic effects such as muscle growth. Other physiological responses may include fat loss where a reduction in body fat can be seen. 

Along with Ostarine and Ligandrol, Andarine is another popular SARM and is often illegally used by sports leagues where it is banned. 

Is Andarine S4 Similar to Ostarine?

Since Andarine is a SARM, it holds some similarities to Ostarine but has a different molecular structure. Ostarine is one of the most well-studied SARMs to date and is undergoing phase 2a clinical trials. Some of the benefits of Ostarine showcase some of the possibilities behind future Andarine research, such as:

  • Improved capillary density

  • Improved muscle vascularization

  • Improved muscle metabolism

  • Reduced muscle wasting diseases

Future research with Ostarine shows it could benefit sarcopenia and menopausal symptoms as seen in mice studies. 

Since Andarine S4 is a similar SARM including its half life, it is beneficial to assess combining with Ostarine or how it could be tested independently for similar effects. 

Is Purchasing Andarine S4 on Reddit Safe?

Many users on Reddit view this site for anecdotal evidence, but this is NOT where research should begin. Scientific databases should be utilized to learn about SARMs and other compounds. 

For starters, locating a reputable resource on where to buy Andarine S4 may be a common question. However, unknown sources of Andarine S4  can contain impurities, unlisted ingredients, and dangerous additives. 

It is imperative that only the highest quality is used for research. If impure products are utilized, all data including the serious side effects of this compound will be invalid. More research will need to be conducted to rectify this misinformation.

With that said, Andarine should not be purchased on Reddit, Etsy, or other online forums. If you purchase Andarine through sellers on these sites, you risk falsified data and research as previously mentioned. This can skew a few weeks of data and render the findings invalid.

What are researchers saying about Andarine on Reddit?:

  • What to expect with test subjects with Andarine

  • Andarine plus Ostarine combinations

  • Research recommendations

  • How to know if Andarine is real

While it is illegal to sell SARMs for human consumption, purchasing cheap products through open-source online platforms risks future research and safety implications regarding accurate data and recorded adverse effects.

Reddit does sell the selective androgen receptor modulator, Andarine S4. There are various postings advertising SARMs powder, “natural” SARMs, and other products. The danger behind these products is they usually aren’t tested by reputable third-party laboratories.

Purchasing Andarine S4 Safely and Is Andarine Legal?

If you have an interest in studying androgen receptors modulators like Andarine S4, there are a few points of concern to inquire about:

  • Purity percentage

  • Where third-party testing was performed

  • USP grade/Food grade additives

  • Certificate of analysis

  • Current and updated legal status

Certificate of Analysis (COA) ensures purity levels in each SARMs batch. The standard reference is 100%, and the minimum requirement should meet 98 percent. If you purchase a product between 100%-101.9%, it indicates that it was above industry standards and purer than the reference sample it was tested against. 

Where Is Current SARMs Research At?

SARMs have a well-known history of their effects on weight loss, muscle mass, and metabolism in recent research. However, research is showing that SARMs could hold the key to other benefits, such as:

  • Breast cancer treatment

  • Prostate cancer treatment

  • Stress urinary incontinence

  • Sarcopenia

The research spearheading these projects could change the field of medicine by offering alternative and efficacious outcomes. The difficulties with research are buying SARMs and adhering to safety tips.

For example, a small research group in the UK found 14 out of 20 SARMs supplements contained ingredients not listed or excluded the primary ingredient it advertised. 

Another Andarine S4 SARM Study On Mouse Uterus

Overview from Study

Selective androgen receptor modulators (SARMs) have been suggested as potential therapies for addressing breast cancer, muscle wasting, and urinary incontinence in females. Although the androgen receptor (AR) is present in the uterus, the effects of SARMs on uterine function remain uncertain.

Study Design

A mouse model was employed to compare the influence of SARMs (Andarine S4, Enobosarm), Danazol, and dihydrotestosterone (DHT) on tissue structure, cell proliferation, and gene expression. 

Ovariectomized mice received daily treatment with the compounds or vehicle control (VC) for seven days.

High-throughput image analysis was used to quantify uterine morphometric characteristics, while immunohistochemistry and RT-qPCR were employed to evaluate protein and gene expression, respectively.


Treatment with GTx-024, Danazol, or DHT resulted in significant increases in body weight, uterine weight, and the surface area of the endometrial stromal and epithelial compartments compared to the VC. GTx-007 treatment did not impact these parameters. 

GTx-024, Danazol, and DHT all substantially increased the percentage of Ki67-positive cells in the stroma, while only GTx-024 affected epithelial cell proliferation.

GTx-007 significantly enhanced the expression of Wnt4 and Wnt7a in the uterus, while GTx-024 and Danazol decreased their expression.


In conclusion, the effects of GTx-024 and Danazol on uterine cells resembled those of DHT, whereas GTx-007 had minimal effects on the parameters examined.

This study has identified specific endpoints that highlight discrepancies in the impact of SARMs on uterine tissue and establishes a framework for preclinical investigations comparing the effects of compounds targeting the AR on endometrial function.

In the future, the cycle length of therapy on these mice should be increased to improve the validity and repeatability of the findings.

Andarine S4 and Lung Cancer Prospects

Lung cancer is a leading cause of cancer-related deaths worldwide, with adenocarcinoma being the most prevalent subtype. Diagnosis involves imaging studies and tissue biopsy, and treatment options depend on factors such as cancer stage, type, and patient health. 

Advances in targeted therapies and immunotherapies have improved lung cancer treatment.

Current therapies include surgery, radiation therapy, and systemic therapy, which encompasses chemotherapy, targeted therapy, and immunotherapy. However, limitations such as treatment resistance and toxicity persis.

Selective Androgen Receptor Modulator and SERMs

Selective estrogen receptor modulators (SERMs) and SARMs have shown potential as anticancer agents. SERMs like tamoxifen have demonstrated efficacy in estrogen receptor-positive lung cancer. SARMs have exhibited anticancer effects in preclinical studies, inhibiting tumor growth in various cancer types.

The androgen receptor (AR) has been extensively studied in different cancer cell lines, including lung cancer. Activation of AR promotes cell growth while inhibiting AR signaling reduces neoplastic transformation and inhibits cell proliferation. AR also plays a role in the migration and invasiveness of cancer cells.

AR activation affects cell cycle regulation, with deprivation of androgen leading to cell cycle arrest. Treatment with SARMs has been shown to suppress proliferation and induce cell cycle arrest in cancer cells.

Andarine, a member of the SARMs class, exhibited anti-growth activity, suppressed migration, and induced apoptosis in lung cancer cells. Gene expression analysis revealed modulation of genes associated with cell cycle progression, apoptosis, and senescence.

Andarine treatment increased senescence-associated β-galactosidase activity, suggesting accelerated senescence. Cellular senescence is a response to stress that can suppress tumor growth. Andarine upregulated genes associated with senescence and cell cycle arrest, providing evidence for increased senescence rate.

Overall, the findings highlight the potential of SARMs, such as andarine, as novel therapeutic agents for lung cancer by targeting AR signaling and modulating gene expression associated with cancer cell proliferation, apoptosis, and senescence.

Andarine Research Studies

Andarine is less prevalent on the research end compared to Ostarine and Ligandrol. Currently, there are no documented clinical human trials using Andarine S4. 

The primary adverse effects of Andarine S4 and other SARMs explained by these studies are temporarily altered vision such as yellow vision and reduced natural testosterone levels in men. Unfortunately, since trials are limited, most of the data out there is anecdotal. Additionally, the Andarine S4 results and effects andarine may show are unknown due to the limited number of trials that include Andarine S4 in the study.
