About

LGD-4033 can suppress endogenous testosterone, and thus post-cycle therapy (PCT) is often required to accelerate HPTA recovery. LGD-4033 exhibits similar effects to the anabolic steroid Dianabol in our experience. LGD-4033, or Ligandrol, is a potent SARM that can produce similar results to RAD 140 in terms of muscle hypertrophy and strength.
If you’re looking for extreme results, it won’t be one to go for, but it can be very effective in a cutting or body recomposition cycle. This binding activates the androgen receptor, signaling cells to increase protein synthesis and growth. Bloodwork (testosterone, lipids, liver enzymes) and medical supervision are critical. Andarine has been around since the early 2000s and, since then, has built up popularity pretty quickly among bodybuilders and performance users. It is beneficial for body toning and cutting as it promotes fat burning without water retention, making it ideal for hardening, toning, and improving body composition.
Selective androgen receptor modulators (SARMs), which  are becoming increasingly popular as performance-enhancing supplements due to their lean muscle mass-building, fat-cutting, endurance, and recovery properties, may be one example. S4 works by selectively binding to androgen receptors in the body, primarily targeting skeletal muscle and bone tissues. "Andarine exerts its effects through high-affinity binding to androgen receptors in skeletal muscle, promoting anabolic activity with minimal androgenic stimulation in reproductive tissues" (Yin et al., Journal of Medicinal Chemistry).

The information on this website has not been evaluated by the Food & Drug Administration or any other medical body. Here we summarized the available dosage data from online communities with the attempt to additionally warn people about the dangers of taking this unapproved drug. The safety and effects of Andarine have not been explored in humans or the studies aren’t publically available.
Don’t forget to split your dosage into two parts and take 25mg in the morning and 25mg in the evening. If we take our dosage in three parts, which is even more optimal, we should the first in the morning, the second during lunch and the last before going to bed. If we take our dosage into two parts, we should take the first in the morning and the second before going to bed.
S23 may be administered to overcome muscle hypertrophy or strength plateaus after this point. S23 is regarded as one of the strongest SARMs for increasing muscle hypertrophy and strength. We can describe the effects of YK-11 as similar to trenbolone concerning increased aggression, anger, paranoia, and anxiety in some users. The above Reddit user gained 15 lb from a 6-week cycle of YK-11, consuming 10 mg/day for the first 3 weeks and 15 mg/day for the remaining 3 weeks. Thus, by decreasing myostatin levels, users can effectively increase anabolism.
10 mg of YK-11 with 20 mg of RAD-140 a day is the best stack in my experience. The value was so high that the lab doctor wanted to schedule an appointment with a general doctor that day. I’ve never had issues with cholesterol prior to starting the RAD-140 cycle. Besides testosterone dropping significantly, cholesterol is very high, almost double what I usually have. In contrast, we classify RAD-140 and LGD-4033 as moderate SARMs with regard to side effects. However, we have seen a few individuals experience mild forms of gynecomastia on Ibutamoren due to raised prolactin levels. The greatest concern for users is the carcinogenic risk of Cardarine.
→ Stacking S4 with RAD-140 or S23 can lead to severe testosterone shutdown. "Combining SARMs with non-suppressive agents like MK-677 or Cardarine can help mitigate fatigue and recovery issues without adding to HPTA suppression." (Rahnema et al., Mayo Clinic Proceedings) Since MK-677 doesn’t suppress testosterone, it pairs well with suppressive SARMs like S4. Because it doesn’t cause water retention or aromatize to estrogen, it stacks well with other dry compounds—but also increases the risk of testosterone suppression, especially when paired with other SARMs. Because of its short half-life, suppression risk, and unique side effect profile, timing, dosing strategy, and post-cycle planning are critical. If visual sides become problematic, reduce the dose or discontinue.
