GW 501516, commonly referred to as Cardarine or Endurobolic, is a research chemical that was initially developed in the 1990s by Ligand Pharmaceuticals and GlaxoSmithKline (GSK) with the intention of treating cardiovascular diseases and metabolic disorders. Its unique mechanism of action, involving the activation of the Peroxisome Proliferator-Activated Receptor δ (PPARδ), made it a compound of interest for various therapeutic applications, including obesity, diabetes, and dyslipidemia. However, it’s important to note that GW 501516 is not approved for use by any governmental health agency and has been linked to various potential health risks, including the development of cancer in animal studies.
GW 501516 has gained popularity in the bodybuilding and athletic communities for its potential to enhance endurance, fat loss, and muscle recovery. It’s crucial to understand that the use of GW 501516 in these contexts is off-label, experimental, and not sanctioned by the medical community. Therefore, any discussion about its usage for bodybuilding purposes is purely informational and not an endorsement or recommendation.
Mechanism of Action
CARDARINE activates PPARδ, a type of nuclear hormone receptor involved in the regulation of genes that control energy expenditure, fat burning, muscle fiber type switching, and inflammation. Activation of PPARδ promotes an increase in the uptake and oxidation of fatty acids in skeletal muscle, liver, and other tissues, leading to improved endurance capacity and potentially facilitating fat loss.
ENDUROBOLIC Use in Bodybuilding
In the bodybuilding community, GW 501516 is reputed for its ability to significantly enhance endurance and recovery times, which allows for more intense and frequent training sessions. Additionally, its fat-burning properties make it attractive for those looking to reduce body fat while preserving muscle mass.
CARDARINE Dosage and Duration
The dosages of GW 501516 reported by users vary, and since there is no clinical guideline for its use in bodybuilding, these dosages are purely anecdotal:
- Beginner: A typical starting dose might be 10mg per day, with some users starting as low as 5mg daily if they are particularly cautious.
- Intermediate: As users become more accustomed to the effects, dosages might be increased to 15-20mg per day.
- Advanced: Some experienced users might go up to 20-30mg per day, although this is less common and increases the risk of potential side effects.
The duration of use typically ranges from 4 to 12 weeks, with many users opting for an 8-week cycle. It’s widely recommended in user forums to follow each cycle with a proper period of discontinuation, allowing the body to normalize.
Reasons for Combining GW 501516 with Trenbolone
- Endurobolic Endurance Enhancement: GW 501516 is reputed to significantly improve cardiovascular endurance, which can be particularly beneficial when using Trenbolone. Trenbolone is known to negatively affect cardiovascular endurance, making it difficult for some users to maintain intense cardio or even weightlifting sessions. GW 501516 may help offset this side effect, enabling users to maintain higher levels of physical performance.
- GW Cardarine Fat Loss: Both compounds have properties that promote fat loss, albeit through different mechanisms. Trenbolone has a strong reputation for enhancing the metabolism and promoting the burning of fat alongside muscle building. GW 501516, through its activation of PPARδ, primarily enhances fat oxidation. The combined use is thought by some to create a synergistic effect that accelerates fat loss while preserving muscle mass.
- Reduced Impact on Cholesterol Levels: Trenbolone can have a negative impact on cholesterol levels, particularly by lowering HDL (good cholesterol) and increasing LDL (bad cholesterol). GW 501516 has been shown in some studies to have a potentially positive effect on lipid profiles by increasing HDL cholesterol. Users believe that combining GW 501516 with Trenbolone could mitigate the steroid’s adverse effects on cholesterol levels.
- Cardarine Mitigating Trenbolone Side Effects: Beyond specific performance and physique enhancements, some users turn to GW 501516 as a general strategy to counterbalance the negative side effects of Trenbolone, particularly those related to metabolic health and cardiovascular strain.
