Research, risks and common questions. Every chapter is free to read here, page by page or as plain text, with every source linked.
- 01 Semaglutide Semaglutide has a large body of clinical research, with results specific to each population and outcome.
- 02 Tirzepatide Tirzepatide produced large effects in several randomized trials.
- 03 TB-500 The name is often used for several peptides. This chapter identifies the peptide tested in each study.
- 04 Retatrutide An investigational medicine studied for weight and metabolic outcomes, with unanswered safety questions.
- 05 GHK-Cu GHK-Cu is sold under names used for multiple molecules, salts, mixtures and routes. The studies apply to the exact material tested.
- 06 Ipamorelin Human data come mainly from acute and postoperative intravenous studies.
- 07 CJC-1295 Published human studies used subcutaneous DAC material and measured hormones, exposure and short-term safety.
- 08 MOTS-c A small peptide studied in metabolism, exercise and aging. Measuring its natural levels in people does not tell us whether taking it improves health.
- 09 Tesamorelin In the United States, approved Egrifta products are indicated to reduce excess abdominal fat in adults with HIV lipodystrophy. Their best-established effect is on visceral fat around the organs, measured by CT.
- 10 Abaloparatide A prescription medicine that stimulates bone formation. Its strongest fracture evidence comes from postmenopausal women with osteoporosis.
- 11 Estradiol A steroid hormone used in several prescription medicines. The product, route and reason for treatment determine which evidence applies.
- 12 Finasteride A prescription medicine for male pattern hair loss and an enlarged prostate. Tablets and skin sprays need separate evidence.
- 13 hCG Fertility treatment uses specific products for defined indications and measured outcomes.
- 14 hGH Diagnosis and product identity define the treatment evidence.
- 15 Levothyroxine Levothyroxine is synthetic T4 used to replace missing thyroid hormone. Evidence and instructions are specific to the salt, product and dosage form.
- 16 Liraglutide A daily GLP-1 medicine used to treat type 2 diabetes and obesity.
- 17 Mecasermin IGF-1 replacement for children with severe primary IGF-1 deficiency.
- 18 Menotropins Fertility treatment with FSH and LH activity.
- 19 Minoxidil Hair regrowth takes time. Keeping it usually takes continued treatment.
- 20 Orforglipron A daily GLP-1 tablet for weight management.
- 21 Oxandrolone An oral anabolic steroid with a long medical history.
- 22 Oxymetholone An oral anabolic steroid studied for anemia and wasting.
- 23 Tadalafil A long-acting medicine for erectile dysfunction, urinary symptoms and pulmonary arterial hypertension.
- 24 Telmisartan Strong evidence for blood-pressure control. Metabolic effects beyond blood-pressure lowering are inconsistent.
- 25 Testosterone The clearest benefits concern specific symptoms in people with confirmed deficiency. The major trials make those benefits, and the risks, easier to separate.
- 26 Albuterol A familiar rescue medicine, with research specific to the condition, formulation and route.
- 27 Armodafinil A prescription wakefulness medicine with evidence tied to specific sleep disorders.
- 28 Bimagrumab An investigational antibody being studied for fat loss and lean-mass preservation.
- 29 Clomiphene Clomiphene is an oral medicine used in fertility care, with studies of ovulation, testosterone, semen and pregnancy across groups.
- 30 Dutasteride Dutasteride lowers DHT by blocking two forms of an enzyme. Its main clinical evidence concerns an enlarged prostate and male-pattern hair loss.
- 31 L-carnitine L-carnitine helps cells use fat for energy. Its medical role centers on deficiency; weight-loss and performance studies give mixed results.
- 32 Lemborexant Lemborexant is a prescription tablet for insomnia. It reduces wakefulness by blocking orexin signals.
- 33 Liothyronine Liothyronine supplies the thyroid hormone T3. Treatment assessment covers symptoms, blood tests and the reason for treatment.
- 34 Mazdutide A GLP-1 and glucagon receptor agonist with approved uses in China and published weight-loss trials in China and the US.
- 35 Methylene blue A hospital medicine and diagnostic dye with early research on memory.
- 36 Modafinil A prescription medicine for excessive sleepiness.
- 37 Nandrolone An injectable steroid studied for muscle loss, anemia and bone disease.
- 38 Nebivolol A prescription beta blocker with evidence on blood pressure, older adults with heart failure, vascular physiology and comparative sexual and metabolic effects.
- 39 Piracetam An older small-molecule drug studied for myoclonus, memory and neurological recovery, with results that vary by condition.
- 40 PT-141 Bremelanotide is a cyclic peptide sold as Vyleesi. Its strongest evidence concerns distressing low sexual desire in a defined group of premenopausal women.
- 41 SS-31 / elamipretide Elamipretide is the peptide in Forzinity, an approved treatment for muscle strength in Barth syndrome. Research in other conditions has produced a mix of early signals and negative trials.
- 42 Survodutide Survodutide combines GLP-1 and glucagon receptor activity. Trials report weight loss and improvements in liver measures, alongside frequent stomach symptoms and treatment withdrawals.
- 43 Alpha-GPC Patient trials, small performance studies and an unresolved safety picture.
- 44 ATX-304 An oral drug under study for metabolism. Formerly called O304.
- 45 Bromantane A Russian drug studied mainly for fatigue and asthenic symptoms.
- 46 Cagrilintide An investigational long-acting amylin analogue with standalone and semaglutide-combination evidence.
- 47 CagriSema An investigational cagrilintide and semaglutide combination, studied for weight management and type 2 diabetes.
- 48 Drostanolone The steroid behind historical Masteron, Masteril and Drolban records.
- 49 Eloralintide Eloralintide is a long-acting amylin drug being developed for weight management. One 48-week phase 2 study provides the main published weight-loss result. Larger ENLIGHTEN studies are recruiting, while nausea, fatigue and treatment persistence need close attention.
- 50 Enclomiphene Enclomiphene raises testosterone through the pituitary-testis pathway. Its studies also measured sperm concentration, symptoms, body composition and safety; results varied by outcome.
- 51 Kisspeptin-10 Kisspeptin-10 has been studied as a way to stimulate reproductive hormones. Small human experiments now include a 24-hour intravenous infusion and repeated subcutaneous exposure over 12 days.
- 52 KPV KPV research includes cells, animal models and engineered delivery systems. The peptide form and the way it is delivered shape each result.
