Ostarine: The perfect anabolic for beginners
Ostarine, commonly known as MK-2866 or Enobosarm, is one of the most widely used and researched selective androgen receptor modulators (SARMs). Originally developed to combat muscle wasting disorders, it has gained considerable support among athletes and bodybuilders for its muscle-preserving and performance-enhancing benefits.
What are the features?
Ostarine selectively attaches to androgen receptors in muscle and bone tissue, where it increases protein synthesis and osteogenesis, respectively. Unlike AAS, which act on androgen receptors throughout the body, Ostarine focuses on specific tissues, decreasing the risk of undesirable side effects such as hair loss, high oestrogen levels, prostate enlargement or virilisation (in women).
Ostarine's practical benefits
Preserving muscle
Ostarine is known for its capability to maintain lean muscle mass, especially during a calorie deficit. Studies have found that it protects against muscle loss while preserving strength and endurance, making it perfect for cutting cycles (Dalton et al., 2011).
Growth of muscles
Ostarine is highly effective in promoting gradual, quality muscle gain without excessive water retention, although its muscle-building capacity is milder than that of stronger SARMs or AAS.
Improved restoration
Athletes report increased regeneration times on Ostarine. Due to reduced muscle breakdown and increased nitrogen retention, Ostarine helps users work out more frequently and at higher intensities.
Healthy bones
Ostarine's beneficial effects also extend to bone density. Studies have shown its ability to increase bone mineralisation, making it a potential therapeutic agent for osteoporosis (Narayanan et al., 2008). Benefits for athletes include reduced risk of injury and increased skeletal support during heavy training.
Possible side effects
Ostarine is generally considered to be safe. However, it is not without side effects, especially when used at high doses or for long periods.
Mild suppression of testosterone
Ostarine can reduce natural testosterone production, especially at higher doses. Post-cycle therapy (PCT) is advised after cycles to restore hormonal balance.
Lipid disorders
Like most SARMs, Ostarine can have an effect on lipid profiles, possibly decreasing HDL (good cholesterol) and increasing LDL (bad cholesterol).
Liver enzymes increased
Some users have reported a slight increase in liver enzymes during use, but these usually return to normal levels after the drug is discontinued.
Unknown long-term effects
Ostarine is a relatively new compound. Its long-term effects on health are not completely understood.
Correct use of the Ostarine
Depending on the user's goals and level of experience, Ostarine is typically taken in doses of 10-30mg per day:
To cut
For muscle maintenance and fat loss, take 10-20 mg per day.
For bulking up
To promote lean muscle growth, take 20-30 mg per day.
Generally cycles last 6-8 weeks. Prolonged cycles or higher doses may increase the risk of side effects, including testosterone suppression. Ostarine has a half-life of approximately 24 hours, making once-daily dosing convenient.
PCT is recommended following Ostarine cycles, especially at doses above 20 mg per day, to restore natural testosterone levels.
Ostarine (MK-2866) is a versatile and easy-to-use SARM that offers significant benefits for muscle preservation, recovery and lean growth. Due to its selective action and mild side-effect profile, it is an attractive option for athletes and bodybuilders looking for an edge in performance and aesthetics. But responsible use, including appropriate dosing, cycle length and post-cycle therapy, is critical to minimising risks and maximising results.
