Best Vitamins & Supplements: Evidence-Based Guides

If you spend any time in fitness or longevity forums, you will eventually encounter people comparing GHRP-2 and GHRP-6 as if choosing between them is a straightforward personal preference — like picking between two protein powder flavors. It is not that simple, and the framing is worth pushing back on before you read anything else. […]

If you have spent any time in nootropic communities, you have almost certainly seen Semax and Selank mentioned together, usually by someone who describes them as "Russian government peptides" with an air of forbidden wisdom. That framing is not entirely wrong. Both compounds were developed in the Soviet Union, both are approved drugs in Russia

When people search for immune system supplements, they usually want one thing: fewer sick days without wasting money on products that overpromise. The reality is simpler and more useful. The best supplements don’t “supercharge” immunity in everyone – they fill common nutrient gaps that make immune defenses work poorly, especially in winter, during stress, or

MK-677 shows up in nearly every "peptide" bodybuilding forum thread, stacked alongside CJC-1295 and ipamorelin, praised for boosting growth hormone without injections. The trouble is that calling it a peptide is factually wrong — and the distinction is not pedantic. MK-677 is a small synthetic molecule, the closest thing the bodybuilding world has to an

Bremelanotide is one of only a handful of FDA-approved peptide drugs that a licensed physician can actually prescribe in the United States today — and almost everything sold online as "PT-141" is a compounded version that is not the same product. That distinction matters enormously, because it is the difference between a therapy tested in

You have probably seen MOTS-c mentioned in longevity forums alongside BPC-157 and Epitalon, often accompanied by claims about mitochondrial optimization and exercise mimicry. The reasonable question is whether this is serious science or the latest peptide hype cycle. The honest answer: MOTS-c is one of the most scientifically grounded peptides in aging research, and it

You have probably seen ipamorelin grouped with CJC-1295 in fitness forums and anti-aging clinics — promoted as a "cleaner" growth-hormone booster that avoids the cortisol spike associated with older peptides like GHRP-2 and GHRP-6. The selectivity claim is real and supported by peer-reviewed data. The leap from "more selective in animal models" to "safe and

CJC-1295 has a lot going for it on paper — a long half-life, a plausible mechanism, and two small clinical trials from a legitimate pharmaceutical company. So you might expect a tidy story about a compound that nearly became a drug and is now sold in grey-market vials. The actual story is messier. CJC-1295 has

GHK-Cu appears on product pages, Reddit skincare threads, and dermatologist TikToks as the copper peptide that resets your skin's DNA, regrows thinning hair, and rebuilds collagen better than anything short of tretinoin. Claims scale from plausible to extraordinary depending on who is talking. Is there real science underneath the marketing, or is this another skincare

Tirzepatide is the second peptide approved by the FDA for weight management and the first to outperform semaglutide head-to-head in a large randomized trial. The honest answer to whether that difference matters for you depends on what you can tolerate, what your insurance covers, and what your physician monitors.
