Oxandrolone: Light Liver Enzyme Elevation After 4 Weeks – What Should I Watch?

Posted by amber464 in Safety & Side Effects - 5 points, 6 comments.

I’ve been on 20 mg daily of oxandrolone for the past month to help with lean mass gain after a slow recovery. When I did my routine quarterly bloodwork, my ALT bumped up from 24 to 38 U/L and AST from 18 to 27 U/L. For me, that feels like a mild flare, no symptoms, just a number that’s a little higher than baseline. I noticed my HRV dipped slightly during that week, but otherwise I felt fine.

I keep a log of every reading and compare trends. My question is: how much rise is considered safe with oxandrolone, and how often should I retest if numbers stay in that 30‑40 U/L range? Should I add any liver‑supportive supplements, or just keep monitoring? I dels on a small dose of milk thistle and a strict low‑phosphorus diet, but I’d love to hear from folks who’ve seen similar results.

• leah_m: I’ve seen the same pattern with oxandrolone myself. When my ALT jumped from 19 to 33 after four weeks, I kept a close eye on it. A rise to 30‑40 is mild, but it’s still a sign the liver is working overtime. I usually re‑check every 4‑6 weeks. If it stays under 40 and I stay symptom‑free, I keep monitoring. If it climbs past 45 or I get nausea or fatigue,_WIDTH I pull the stick. I do a handful of milk thistle and NAC, and I watch my protein and phosphorus closely. How long do you keep it going
• hank_m: Tbh i’d keep it under 8‑week blocks if the enzymes stay under 40, re‑checking every 4 weeks; if it creeps higher or you notice any fatigue or nausea I’d cut it short, use milk thistle/NAC and maybe reduce the dose. Keep an eye on the trend.
• hank_m: Tbh i just keep it on a 4–6 week cycle and re‑check the labs after each break, same as you, and if the ALT/ASToder stays under 40 with no symptoms i let it run. Then i usually give the liver a month off, re‑test, and if it stays flat i can start the next round. It’s all about staying in that safe zone and giving it a rest.
• amber464: Thanks for theheads up on the cycling idea, imo that aligns with how I’m tracking mine too. I’m curious though, have you ever seen enzymes creep past 40 without symptoms? I’m at 38/27 now and wondering if staying under 40 is a hard ceiling or just a guideline. Also, your dip in HRV with mine, any tips on linking that to the enzyme rise? I’ll keep the milk thistle going but might add dandelion root if it’s safe.
• amber464: Thanks for the concrete advice, 8-week blocks and rechecking every 4 weeks lines up with my logging. My ALT’s at 38 now, which felt like a mild bump but no symptoms, so I’ll stick with that trend. I’m already on milk thistle daily, but I’ll add NAC if it’s suggested. How’d you handle dosing if enzymes crept up? Did you taper or just adjust? I’ll keep tracking HRV too, it did dip a bit that week, which I’m half-arguing could be unrelated.
• amber464: NAC helped me too, any changes in your NAC dose or timing if enzymes trend up? I’m logging daily numbers now, but wondering if 5-week rechecks vs. 4 might matter if I stay stable.
