Steroids & Anabolics

SARMs (Ostarine, LGD-4033, RAD-140, S-4)

Street names: Ostarine, MK-2866, LGD-4033, Ligandrol, RAD-140, Testolone, S4/Andarine, Cardarine, GW-501516, MK-677

⚡What it does

  • Selective androgen receptor modulation: muscle/strength gains weaker than steroids with (claimed) fewer androgenic sides; MK-677 (a ghrelin agonist, not a SARM) boosts appetite/GH

⚠Key risks

  • ZERO human approval — no long-term safety data anywhere; liver enzyme elevations documented; liver injuries reported to FDA
  • Suppression: they shut down natural testosterone — users need real PCT, which grey-market sellers never mention
  • Cardarine (GW-501516) caused cancers in rodent studies at human-equivalent doses — the mouse study that killed its development
  • Sold as 'legal steroids' with fake COAs; most products are underdosed or mislabeled
  • Vision side effects (yellow tint, night blindness) with S-4
  • WADA-banned — tested athletes pop hot regularly

✚Overdose signs

  • Jaundice, dark urine (liver)
  • Severe suppression symptoms: depression, libido collapse
  • Vision changes (S-4)
