You can buy steroids from various sources depending on the type and legality:

• Research and pharmaceutical-grade steroids can be purchased from chemical suppliers like Sigma-Aldrich or Biosynth, which offer steroids and sterols primarily for scientific or medical use

• Anabolic steroids for bodybuilding are available from specialized online stores such as Pharmax-store, which claims to sell original anabolic steroids including injectables and oral forms with delivery options designed to avoid customs issues in Europe

• Legal steroid alternatives and supplements that mimic anabolic steroids without legal risks can be bought from reputable online retailers like CrazyBulk. These products include muscle-building supplements such as D-Bal (a legal Dianabol alternative), Testo-Max (a testosterone booster), and others designed for bulking, cutting, and endurance enhancement

• Steroids prescribed for medical use (corticosteroids) are generally only available with a prescription from healthcare providers and pharmacies. Some mild forms like creams or nasal sprays can be bought over the counter in pharmacies

• Some online steroid shops like MegaGear offer specific anabolic steroids such as Trenbolone enanthate for muscle growth, but these are typically intended for experienced users and may have legal restrictions depending on your country

Important note: The legality of buying anabolic steroids varies by country. Many anabolic steroids are controlled substances and illegal to buy or use without a prescription in many places. Legal steroid alternatives are a safer option for muscle building without legal or health risks. Always ensure you are complying with local laws and consult a healthcare professional before using steroids or supplements.
