Key Benefits

  • Enhanced Fat Burning & Endurance

  • Lean Muscle Preservation

  • Improved Cardiovascular Performance

  • Body Recomposition Support

  • Metabolic Efficiency Enhancement



Ingredient Breakdown
GW501516 (Cardarine) – A PPARδ agonist widely studied for its ability to enhance fat oxidation, increase endurance, and improve metabolic efficiency. It is commonly used during cutting phases and endurance-based protocols.

MK-2866 (Ostarine) – A selective androgen receptor modulator (SARM) known for its muscle-preserving properties. Ostarine is well-suited to cutting cycles due to its ability to maintain lean muscle mass while in a caloric deficit.

TWP Ostalean is a dual-compound formula by The Warrior Project combining GW501516 (Cardarine) and MK-2866 (Ostarine). It is designed for fat loss, endurance enhancement, and lean muscle preservation, with 60 capsules per bottle.

GW501516, also known as Cardarine, is a PPARδ agonist widely studied for its ability to enhance fat oxidation, increase endurance, and improve metabolic efficiency. It is not a SARM but is commonly used in SARM-based protocols.

MK-2866, also known as Ostarine, is a selective androgen receptor modulator (SARM) known for its muscle-preserving properties. It is well-suited to cutting cycles due to its ability to maintain lean muscle mass while in a caloric deficit.

Key benefits include enhanced fat burning and endurance, lean muscle preservation, improved cardiovascular performance, body recomposition support, and increased metabolic efficiency. The dual-compound formula targets both fat loss and muscle retention simultaneously.

TWP Ostalean should be taken according to a structured cycle protocol. Capsules are typically dosed once daily. Due to the inclusion of GW501516, cycle length should be carefully managed, and a post-cycle therapy (PCT) plan should be in place.

This product is designed for experienced users familiar with SARM and performance compound supplementation. It is best suited to those undertaking a cutting or recomposition phase who understand cycle management and support protocols.

No. TWP Ostalean is a two-compound formula not suitable for beginners. Only experienced users with a clear understanding of GW501516 and MK-2866, their effects, and appropriate cycle management should use this product.

Yes. TWP Ostalean is specifically designed for cutting and recomposition phases. Cardarine enhances fat oxidation and endurance while Ostarine supports lean muscle retention during a caloric deficit.

The active ingredients are GW501516 (Cardarine) and MK-2866 (Ostarine). Each bottle contains 60 capsules. Full dosing details per capsule are available on the product label and should be reviewed before use.

TWP Ostalean is available through Cross The Limits, an authorised UK retailer. Orders placed before 4pm are dispatched the same day, with free UK shipping on orders over £89.
