Top Peptides for Erectile Dysfunction
Peptides are increasingly studied for their potential to support vascular function, circulation, and nitric oxide production. This guide highlights four peptides currently under investigation for their potential roles in enhancing vascular health and blood flow dynamics.
PT-141 (Bremelanotide)
Studied for its melanocortin receptor activity, PT-141 has been a focus in research examining neural pathways associated with arousal and circulatory responsiveness. It’s unique in that it works through central mechanisms, rather than targeting the vascular system directly.
Kisspeptin-10
This peptide is explored for its influence on hormone regulation, particularly in the hypothalamic-pituitary-gonadal (HPG) axis. Its potential to affect luteinizing hormone (LH) release makes it of interest in studies related to endocrine feedback and reproductive signaling.
Oxytocin
Oxytocin, a naturally occurring peptide hormone, has been studied for its effects on trust, bonding, and social behavior—but also for its role in smooth muscle contractions and vascular tone, which are relevant in circulatory research models.
BPC-157
Recognized for its regenerative properties, BPC-157 is under investigation for its potential to improve endothelial function and support tissue repair. Researchers are examining its applications in promoting angiogenesis and maintaining healthy blood flow in vascular models.

Top Recovery Supplements for Fighters
Fighters endure intense training cycles that push their bodies to the limit, making recovery just as important as performance. This guide explores the top muscle recovery supplements commonly studied and used in the fight community to help support muscle repair, reduce soreness, and accelerate bounce-back time between sessions. Branched-chain amino acids (BCAAs) and essential amino acids (EAAs) are central to recovery protocols for their role in muscle protein synthesis and preventing muscle breakdown during high-volume training. Creatine is another foundational supplement that not only improves performance but also supports recovery by aiding in ATP regeneration and reducing inflammation after strenuous bouts.
Anti-inflammatory compounds like curcumin and omega-3 fatty acids have also been researched for their ability to reduce delayed onset muscle soreness (DOMS) and support joint health—two critical components for any combat athlete. Glutamine and magnesium are often included in recovery stacks due to their involvement in reducing muscular fatigue and supporting electrolyte balance, especially in fighters who experience high sweat loss during training. Finally, sleep-supporting supplements like glycine and ashwagandha are explored for their effects on cortisol regulation and restorative sleep, both of which directly impact muscle regeneration and mental resilience.
For fighters looking to stay sharp, recover faster, and maintain peak conditioning, a well-rounded recovery stack may offer key advantages. Click here to explore the full guide to muscle recovery supplements for fighters.
8 Types of Creatine
Creatine is one of the most researched and widely used supplements in sports nutrition, known for its role in boosting strength, muscle mass, and workout performance. While creatine monohydrate is the most common form, this guide explores eight different types of creatine and how they differ in absorption, stability, and effectiveness.
Among the most studied is Creatine Monohydrate, praised for its proven track record and cost-effectiveness. Creatine Hydrochloride (HCL) offers enhanced solubility and may reduce bloating for those sensitive to monohydrate. Buffered Creatine (Kre-Alkalyn) is designed to resist stomach degradation, potentially improving stability. Creatine Ethyl Ester was once popular for better absorption, though research has been mixed on its efficacy.
Other variations include Creatine Magnesium Chelate, which binds creatine with magnesium to aid muscle contraction; Creatine Nitrate, valued for its added nitric oxide boost; Creatine Citrate, known for better solubility but requiring higher doses; and Liquid Creatine, which is convenient but often questioned for its shelf stability.
