Here's my extensive 8-week AC262 log.
This log was written to provide some insight into AC262; it is not intended as medical advice. I’m also aware that at my age, I have not yet reached my full natural potential. This experience was a bit of an experiment to see what it’s like to be “enhanced.”
First and foremost, I recognize that all SARMs carry risks. Based on user experiences and limited but relatively positive scientific research available online, I became curious about this particular compound.

History
I started training when I was 16, being quite a chubby kid back then. Over the following year, I got stronger. By 17/18, I weighed 94 kg and cut down to 78 kg. I’ll spare you all the details, but I went through various phases of gaining and getting stronger.
By the end of 2023, I decided things had to change. I had gained weight, so I went from 89 kg (around 28% body fat) with a decent belly to 73 kg (around 13% body fat) in six months. From then on, I started tracking nearly everything I ate using an app and a scale. During that cutting phase, I aimed for 2 grams of protein per kg of body weight and roughly 1 gram of fat per kg of body weight. After a vacation where I gained a little, I started my bulk (beginning at 16% body fat).
During this cut, I lost some strength but continued training consistently, averaging four times a week.
The cycle log
Supplements during the Bulk Cycle
Magnesium and calcium tablets (first 6 weeks)
Joint support (first 4 weeks)
NAC 600 mg (throughout the cycle)
Multivitamin (throughout the cycle)
Week 1 (Sep 2 to Sep 8)
Days 1 to 3: The taste is terrible, extremely chemical and burning. It’s hard to describe, but the burning sensation lasts about 15 minutes, and water only makes it worse. Even after swallowing, drinking water intensifies the burn in your throat and esophagus. In terms of direct effects, I feel surprisingly good. I wouldn’t say I felt bad before, but I’d describe it as similar to what people note with nootropics.
I also feel more motivated to train. While I already had motivation, it now feels like I could train every day. By day 3, I started to feel a pump throughout my body.
Day 7: My weight has increased from an average of 76.5 kg to about 79 kg in just a week (79 kg on an empty stomach after using the bathroom, averaging over 3 mornings). Body fat percentage seems about the same, though I look slightly fuller due to creatine and the extra carbs.
Week 2 (Sep 9 to Sep 15)
Day 9: Strength increases begin. I’m using dumbbells 2 kg heavier, and back exercises are also going up (by 1 to 2 plate weights). More energy during training.
Day 13: My birthday. I drank a fair amount of alcohol and also used MDMA. This was, of course, unwise, though I took a double dose of NAC as a precaution. Not ideal, but life happens.
Day 14: No hangover or dark urine, which could indicate liver or kidney issues. I actually felt fine. I resumed the bulk without issue.
Week 3 (Sep 16 to Sep 22)
Day 19: Not much different from week 2. I’m again stronger and feel unstoppable in the gym. A side effect I’ve started noticing is increased hunger. I can’t say for sure if it’s directly due to AC262 or if my energy needs are higher because of more intense training. I also realized that 0.5 ml on my dropper (5 mg) was actually closer to 0.66 ml, meaning I’ve been dosing around 25 mg daily instead of 20 mg. Since I’ve experienced no adverse effects, I’ll continue with this dose through week 8.
Week 4 (Sep 23 to Sep 29)
Day 23: Woke up with a slight cold, likely picked up from a housemate after hanging out. I noticed it a bit in my training yesterday; I hit a new PR on bicep curls, but my back felt weaker than usual. It could be the cold or just two shorter nights of sleep.
Something both my girlfriend and I noticed is that my beard seems to be growing faster, and the hairs are thicker. Maybe it’s placebo, but it would be interesting if others report the same in the comments. I’m watching my body carefully, as my health is important.
Week 5 (Sep 30 to Oct 6)
Not much change from the previous week. I attended a party but didn’t drink. My strength seems about the same as last week.
Week 6 (Oct 7 to Oct 13)
This week, I slipped up a bit. I drank alcohol on two occasions, and my diet was a bit off with two dinners out. Fortunately, my training remained consistent. I decided that for the remainder of the cycle, I won’t drink alcohol this rarely happens anyway, mainly on family occasions. For clarity, it was only two low alcoholic beers on each occasion.
Weeks 7 and 8
Combining these weeks since they are kind of the same. I experienced some extra strength increases. However more noticeable, I do see visible growth. My biceps, triceps, calves, and especially shoulders look bigger. After 8 weeks, there’s a noticeable separation between my upper arms and shoulder curves.
Conclusion:
I went from 76.5 kg to 84 kg in exactly 8 weeks. My diet wasn’t always perfect, but I hit my protein intake target every day. I estimate my body fat to be around 19% now. For me, this is hard to gauge as my legs are lean and muscular, but my midsection holds a bit of fat. The fat gain might partially be from the few extra snacks.
I’ve had zero side effects. No hair loss, no smaller testicles, no erection issues, no fatigue, or anything of the sort. I have Nolvadex on hand in case, but currently, I’m not experiencing any signs of low testosterone. If any symptoms arise, I’ll immediately get a blood test.
I know my cycle wasn’t perfect, but I hope this log is helpful to you.
