For bodybuilders and athletes seeking to achieve a dry, hard, and exceptionally vascular physique, S4 (Andarine) remains a top-tier Selective Androgen Receptor Modulator (SARM). Renowned for its ability to enhance muscle density, promote fat loss, and significantly increase vascularity, S4 is a premier choice for cutting phases and pre-contest preparation. Understanding its unique side effect profile is key to a successful cycle. Sourcing a genuine product from a reputable supplier ensures you get the desired results. When you buy S4 online, choosing Dragon Pharma guarantees you receive a quality compound designed for performance.
S4's effects are highly visual and performance-oriented. Users experience a notable increase in muscle hardness and density, giving a grainy, defined look. It significantly enhances vascularity, making veins more prominent. Alongside these visual changes, users report solid increases in strength and a improved ability to burn fat while preserving lean muscle tissue in a calorie deficit. It works by selectively targeting androgen receptors in muscle and bone tissue. A research paper on PubChem details its structure and mechanism, highlighting its high affinity for androgen receptors, which explains its potent effects on muscle composition.
S4 has a relatively short half-life (approximately 4-6 hours), which influences dosing strategy. A common and effective protocol is to split the total daily dose. A standard dosage for male athletes ranges from 50 mg to 75 mg per day. It is advised to start at 50 mg daily, split into two doses (e.g., 25 mg morning, 25 mg evening) to assess tolerance to vision side effects. The dose can be gradually increased to 75 mg (25 mg three times per day). Some advanced users go up to 100 mg, but this increases the risk and intensity of side effects. Cycle length is typically 8-10 weeks.
S4 is primarily used during cutting and recomposition phases. It is suppressive, so a Post-Cycle Therapy (PCT) is recommended after cycles longer than 8 weeks. It stacks excellently with other cutting compounds.

S4's side effect profile is unique, with its impact on vision being the most discussed.
Managing these risks involves dose splitting, reasonable cycle lengths, and a proper PCT if needed.
The prevalence of underdosed SARMs makes sourcing from a reliable manufacturer critical. An underdosed product will fail to deliver the promised hardening and vascularity, while an impure one could exacerbate side effects. Dragon Pharma's commitment to quality ensures that each 25mg tablet is produced to exacting standards, providing consistent and predictable results cycle after cycle. This allows users to accurately manage their dosage and mitigate the unique vision-related side effects associated with this powerful compound.
The most common vision side effects are a temporary yellow tint or hue to your vision and difficulty seeing in dark or low-light conditions (often called "night blindness"). This occurs because S4 can bind to receptors in the eyes. These effects are dose-dependent and completely reversible once you stop taking the compound. They usually appear at doses above 50mg per day and subside a few days after your last dose. Splitting your daily dosage can help reduce the intensity of this side effect.
It depends on the cycle length and dosage. For a moderate cycle of 50mg per day for 8 weeks, a mild PCT is advisable to help restore natural testosterone levels quickly. For longer cycles or higher doses (75mg+), a standard PCT is recommended due to more significant suppression. A common protocol is 4 weeks of Nolvadex (Tamoxifen) at 10-20mg per day or Clomid (Clomiphene) at 25mg per day. It's always best to have PCT compounds on hand before starting your cycle.
S4 is not typically the first choice for bulking. While it can provide lean mass gains and strength increases, its true strength lies in its ability to create a hard, dry, and vascular look, which is more beneficial during cutting or recomposition phases. For pure mass gain, other SARMs like LGD 4033 (Ligandrol) or RAD 140 (Testolone) are generally more effective as they promote more significant water retention and mass.
It is generally not recommended for women. While its androgenic side effects are less pronounced than some compounds, the risk of virilization (masculinizing side effects like voice deepening or clitoral enlargement) is still present. Additionally, the vision side effects can be concerning. Women are advised to seek much milder and more female-friendly alternatives like Ostarine (MK-2866) at very low doses if they choose to use any PEDs.
Both are popular cutting SARMs, but they have different strengths. Ostarine is milder, better for muscle preservation and joint health, with minimal side effects. S4 is stronger in terms of producing visual changes—it provides more noticeable muscle hardness, density, and vascularity. However, S4 comes with the unique vision side effects and is slightly more suppressive than Ostarine. Ostarine is often recommended for beginners, while S4 is a step up for those seeking more dramatic visual results from a cutting cycle.
