Peptides are short chains of amino acids that naturally occur in the body, acting as hormones such as insulin, oxytocin and vasopressin, or as fragments released during protein digestion.In recent years, a wave of interest has turned these molecules into purported therapeutic agents for everything from weight loss to anti‑ageing and tissue repair. Prescription drugs like semaglutide (Wegovy) and tirzepatide (Mounjaro) are synthetic peptides that have undergone rigorous clinical testing and are approved for specific medical uses.However, a large portion of the market consists of unregulated, experimental peptides sold for self‑administration. These products often bypass the strict approval processes required for medicines, raising serious safety concerns.Who is using these products? Initially confined to a niche of powerlifters and bodybuilders in the 2010s, the audience has expanded dramatically. Influential figures such as podcaster Joe Rogan have promoted combinations like the “Wolverine stack” (BPC‑157 and TB‑500) for injury recovery, while other compounds—CJC‑1295, MK‑677, ipamorelin, and GHK‑Cu—are marketed for muscle growth and anti‑ageing. Social media platforms are now flooded with instructions on purchasing and injecting these substances.Scientific backing is scant. Reviews of the literature reveal that most experimental peptides have only been tested in animal or cell models. For example, BPC‑157 shows promise for tendon and muscle repair in pre‑clinical studies, but no randomized human trials have validated these effects. Similarly, TB‑4 and its synthetic analogue TB‑500 have demonstrated limited blood‑vessel formation in laboratory settings, yet human data are absent and both are listed as prohibited substances by the World Anti‑Doping Agency.Researchers also highlight a critical knowledge gap: dosage, frequency and treatment duration remain undefined, making self‑administration a gamble.Legal landscape in the UK is clear that peptides not classified as medicines fall outside the Medicines and Healthcare products Regulatory Agency’s (MHRA) remit. If a seller makes medicinal claims, the product must hold a marketing authorisation under the Human Medicines Regulations 2012. The MHRA warns that labeling items as “research use only” does not shield vendors from enforcement when evidence shows the products are intended for human consumption.Health risks are multi‑fold. Experts caution that benefits observed in animal studies do not guarantee safety in humans. Contamination with harmful impurities or bacterial endotoxins can trigger severe reactions, including septic shock. Injecting excess natural peptides may disrupt the body’s tightly regulated hormonal balance, potentially affecting multiple physiological pathways.There is also theoretical concern that augmenting peptide levels could accelerate tumour growth, as some cancers over‑express certain peptide pathways. While no direct cases have been documented, the possibility underscores the need for caution.Additional dangers include improper injection techniques (e.g., air embolism), unknown interactions with existing medications, and the lack of systematic monitoring of long‑term effects. As one researcher put it, “If something goes wrong, users may never notice until irreversible damage has occurred.”

The UK medicines regulator has opened an inquiry into a growing number of clinics that sell injectable peptides while promoting them as cures for everything from ageing to injury recovery. The investigation, disclosed by the Guardian, focuses on whether these businesses are breaching the Human Medicines Regulations 2012 by making unauthorised medicinal claims. Interest in peptide‑based treatments has surged in recent years, driven by social‑media influencers, some healthcare professionals, and direct‑to‑consumer marketers. Yet the scientific foundation for most of these claims is weak, with the bulk of research confined to animal models or cell‑culture studies. According to an MHRA spokesperson, any clinic that advertises a peptide as having therapeutic benefits must treat the product as a medicine, which triggers a comprehensive regulatory framework. "If clinics offering peptide injections make medicinal claims for those treatments, the products will be considered medicines and subject to regulation," the agency warned, adding that it will act against any identified breaches. Guardian reporters identified several high‑ranking Google search results that list peptides such as Cortexin (promoted for neuroprotection), BPC‑157 (claimed to aid tissue repair), and Thymosin Alpha (advertised to boost immunity). After being contacted, one clinic removed the statements from its website. Another clinic, while acknowledging the limited human evidence, continued to market seven specific peptides, providing price lists (£350 per month for a single peptide, £450 for two) and offering delivery via vials, syringes, or pre‑filled pens for an additional fee. During a free consultation, a clinician highlighted the experimental nature of the products, noting the absence of large‑scale, randomised clinical trials and recommending a break of four to eight weeks between treatment cycles to mitigate unknown risks. The clinician suggested BPC‑157 for post‑exercise recovery, describing it as a facilitator of cellular repair and blood flow, but warned against its use in smokers or individuals with a family history of cancer due to potential angiogenic effects. The second peptide discussed was MOTS‑C, portrayed as a mitochondrial enhancer that could improve stress resilience, lower insulin resistance, and reduce visceral fat by boosting cellular energy production (ATP). The MHRA confirmed it is reviewing whether the clinician’s statements constitute medicinal claims. The clinic defended its approach, emphasizing that it clearly informs clients that the peptides are not licensed medicines and that the evidence base is largely pre‑clinical. In a broader statement, Lynda Scammell, head of borderline products at the MHRA, explained that peptide products may be marketed as cosmetics, supplements, or medicines, and each case is assessed on its intended use, pharmacological effect, and supporting evidence. She added, "We disregard claims that products are for ‘research purposes’ if it is clear that such claims are being used as an attempt to avoid medicines regulations." Peptides are short chains of amino acids, some of which occur naturally (e.g., insulin). While synthetic peptide analogues like semaglutide and tirzepatide have secured approval for weight‑loss treatments, many of the compounds promoted by these clinics remain experimental and lack the rigorous safety and efficacy testing required for medicinal products.

More than 100 United States‑based international law scholars have signed an open letter denouncing the recent US‑Israeli strikes on Iran as a violation of the United Nations Charter and potentially amounting to war crimes. The letter, released on Thursday, asserts that the campaign – launched on February 28 – proceeded without UN Security Council authorization and without credible evidence of an imminent Iranian threat. According to the scholars, the legal basis for force against another state exists only in self‑defence against an actual or imminent armed attack, or when expressly sanctioned by the Security Council. Iran has not attacked the United States or Israel, and the Security Council did not approve the operation. The experts organize their concerns into four categories: the legality of the war decision, the conduct of hostilities, threatening rhetoric from senior officials, and what they describe as the dismantling of civilian‑protection safeguards within the US defence establishment under Secretary of Defense Pete Hegseth’s “gloves‑off” approach. Among the most alarming incidents highlighted is the strike on a primary school in Minab, Iran on the first day of the conflict, which killed at least 175 people, the majority of them children. The letter also cites attacks on hospitals, water treatment facilities, and energy infrastructure, emphasizing that schools, health facilities, and homes have been targeted. The signatories condemn public statements by senior US officials, including a mid‑March remark by former President Donald Trump that the United States might strike Iran “just for fun,” and early‑March comments from Pentagon chief Pete Hegseth dismissing “stupid rules of engagement.” They argue that such rhetoric reflects an “alarming disrespect” for international humanitarian law, which is designed to protect civilians and combatants alike. Financially, the letter notes that the war is costing US taxpayers up to $2 billion per day, underscoring the broader economic burden of the conflict. The open letter was co‑authored by prominent legal scholars such as Yale Law School’s Oona Hathaway, former State Department legal adviser Harold Koh, NYU’s Philip Alston, and former Human Rights Watch chief Kenneth Roth. While the authors focus on the United States’ conduct, they warn of a heightened risk of atrocities throughout the region. Emphasizing the need for consistent application of international law, the scholars write: “We urge US government officials to uphold the UN Charter, international humanitarian law, and human rights law at all times, and to publicly make clear US commitment to and respect for norms of international law.”

Israel's ongoing attacks on Lebanon have led to a significant deterioration of the country's healthcare infrastructure. In the past month, 53 medical workers have been killed, 87 ambulances and medical centers destroyed, and five hospitals forced to close, according to Lebanon's Ministry of Public Health.The attacks have resulted in the displacement of 1.2 million people, putting an enormous strain on the already struggling Lebanese healthcare system. Experts and analysts say that Israel's actions are part of a broader strategy to force people out of southern Lebanon.“Israeli strikes and blanket evacuation orders are cutting people off from care and shrinking the space for health services to function,” said Luna Hammad, Lebanon medical coordinator for Doctors Without Borders (MSF). MSF has documented a pattern of attacks affecting healthcare.The destruction of healthcare infrastructure has also led to a significant increase in emergency room admissions. Healthcare facilities are under higher strain than before, with many patients needing treatments like chemotherapy, radiotherapy, and dialysis being transferred further north.Direct attacks on healthcare workers and facilities have been documented by Human Rights Watch (HRW), which has noted repeated, apparently deliberate attacks on medical workers in Lebanon. Medical workers and healthcare facilities are protected under international humanitarian law, and Israel's attacks on medics in 2024 were described as an apparent war crime by HRW.The attacks on healthcare infrastructure during times of war are not new. Forensic Architecture has documented systematic targeting of hospitals and healthcare workers in Gaza. Experts warn that such attacks have compounding effects, including treatable injuries getting worse, war wounds not healing properly, and long-term consequences.Experts and analysts say that the attacks are unlikely to cease as long as the pattern of impunity continues. Lebanon's government has a responsibility to ensure accountability and to give jurisdiction to the International Criminal Court (ICC) to investigate and prosecute war crimes.

Tiger Woods, the renowned golfer, was arrested on March 27 for driving under the influence (DUI) in Florida after his car crashed on a residential road. According to body camera footage, Woods told a Sheriff's deputy that he was 'talking to the president' during the incident.The footage shows Woods appearing astonished as he was handcuffed after failing a sobriety test. He was found to have hydrocodone in his possession, a painkiller that contains an opioid. Woods claimed he had taken 'a few' medications earlier in the day but denied drinking any alcohol.Woods, 50, pleaded not guilty to the charges and later announced that he would be stepping away indefinitely 'to seek treatment and focus on my health'. The incident has raised concerns about Woods' health and well-being, particularly given his history of surgeries, including seven back surgeries and over 20 surgeries on his right leg.

Liverpool head coach Arne Slot has expressed no regrets over his treatment of Mohamed Salah, emphasizing that the decision to leave the club was solely the forward's. Salah announced his departure from Liverpool at the end of the season, 12 months before his contract was set to expire.Slot faced the media for the first time since Salah's announcement and chose not to disclose the reasons or timing of the forward's decision. He believes it is up to Salah to explain his reasons for exiting the club. The Liverpool head coach was questioned about being perceived as the 'bad guy' behind Salah's departure, particularly following the player's criticism at Leeds in December. Slot responded by stating that he wouldn't have handled the situation differently and doesn't regret many of his decisions during his time with Salah.Slot also denied that allowing Salah to leave on a free transfer indicates the club is happy to let him go. He emphasized that Salah has earned the right to decide when he should leave, having done many great things for the club.As Liverpool prepares for their FA Cup quarter-final against Manchester City, Slot confirmed he is heavily involved in planning for this summer's transfer window.

Eight Muslim-majority countries, including Pakistan, Turkey, Egypt, Indonesia, Jordan, Qatar, Saudi Arabia, and the United Arab Emirates, have issued a joint statement strongly condemning Israel's one-sided bill to impose the death penalty on Palestinians convicted of fatal attacks.The countries expressed deep concern over the conditions of Palestinian prisoners in Israeli detention, warning of mounting risks amid reports of ongoing abuses, including torture, inhumane and degrading treatment, starvation, and the denial of basic rights.Israel's parliament, the Knesset, passed the controversial bill on Monday, a one-sided law that will not impose the same penalty on Jewish Israelis convicted of killings. The law has been criticized by the United Nations and the European Union, but Israel's ally, the United States, came out in support of its sovereign right to determine its own laws.The eight countries also cautioned against measures by Israel that risk further inflaming tensions on the ground, stating that these practices reflect a broader pattern of violations against the Palestinian people.

Israel's death penalty law has significant implications for Palestinians, potentially leading to increased tensions and human rights concerns. The law, which allows for the imposition of the death penalty for certain crimes, has been met with criticism from human rights groups and Palestinian authorities.The consequences of this law are far-reaching, affecting not only Palestinians convicted of crimes but also the broader Israeli-Palestinian conflict. The law may be seen as a provocation by Palestinian leaders, potentially leading to increased violence and instability in the region.Human rights groups have expressed concerns about the fairness of trials and the treatment of Palestinian prisoners in Israeli custody. The law has also been criticized for its potential to disproportionately affect Palestinians, who make up a significant proportion of Israel's prison population.

Tiger Woods, the renowned golf superstar, has made a significant decision to step down as the US captain for the 2027 Ryder Cup. This move allows him to focus on his health and well-being, following a recent court ruling that granted him permission to travel abroad for comprehensive inpatient treatment.A Florida judge approved Woods's request, citing his need for an “intensive, highly individualized and medically integrated program” away from media scrutiny. Woods's lawyer argued that his client's complex clinical presentation required a level of care that couldn't be safely provided in the United States.The decision comes on the heels of Woods's recent misdemeanor driving under the influence (DUI) charges following a rollover crash in Jupiter, Florida. Woods had pleaded not guilty to the charges, which included property damage and refusal to submit to a urinalysis. The incident revealed that Woods had been swearing profusely, showed signs of lethargy, and had extremely dilated pupils.Woods has been open about his need for treatment, stating that he aims to achieve lasting recovery. In a public statement, he expressed his commitment to prioritizing his health and seeking the necessary support. The PGA of America, PGA Tour, and Augusta National Golf Club have all offered their support for Woods during this challenging time.The PGA of America has announced that they will provide further updates on the Ryder Cup Captaincy when appropriate. For now, Woods's focus remains on his health and well-being, and the golf community rallies around him in support of his journey toward recovery.
