Challenge: Drop body fat from 14% to 10% in just 4 weeks

20 replies10 peopleAug 17, 2026☆ Follow
Summary

Can someone safely reach 10% body fat from 14% in only four weeks while preserving muscle?

The original poster plans a 1000 kcal daily deficit plus Retatrutide, TRT, and HGH to lose 4 kg of fat before a photoshoot. Most replies warn that rapid cuts increase muscle loss, especially at lower body-fat levels, and suggest extending the timeline to eight weeks or more. Several users mention harsher compounds like tren or clen for faster results but highlight side effects and interactions with retatrutide. Water manipulation and carb cycling are also discussed for the final week.

What this discussion establishesWhere people disagree

Whether a four-week timeline is worth the extra muscle loss and health risks versus taking more time

Still open

Whether the goal is realistically achievable without extreme or unhealthy methods

Nothing here is advice.

I set a personal goal to hit 10 percent body fat even if I may not stay there long term. I have never been that lean and want to see how it looks. Right now I sit at 14 percent with a photo attached. I will run a strict four-week diet and share weekly progress pictures. My current stats are 88 kg at 181 cm so I need to drop about 4 kg of fat while holding a 1000 kcal daily deficit. I just finished a high-calorie phase. My current compounds are Retatrutide at 4 mg aiming for 5 mg per week with omeprazole for heartburn, TRT at 150 mg per week possibly raised to 200 mg to hold muscle, and HGH at 3 IU daily. I will keep posting updates and welcome any suggestions on how to make it work better.

A milder deficit over eight weeks would probably spare more muscle. You are not starting from 40 percent so the muscle loss percentage will be higher as body fat gets lower. Adding a steroid cycle can help but moving to 200 mg test plus 3 IU of HGH means you are no longer on TRT and are enhanced which is fine if you are honest about it. There is no strong reason to rush straight to 10 percent. Take your time and do it properly.

Just wondering why the deadline is set at four weeks.

I would not turn this into a short-term challenge. Aim for the target gradually instead. Focus on losing fat while keeping your weight stable. I weigh 70 kg now and have finally started to reduce belly fat after a long period without dropping muscle. Even with enough protein, daily HGH shots, and consistent training the strength difference between 74 kg and 70 kg is clear. The same weights and reps feel harder now. Pay attention to what your body tells you rather than forcing a plan your mind made up. This is not a race.

Fat loss gets tougher the leaner you become because the body clings to remaining stores more tightly. Raising test does not always aid a cut and can actually increase hunger or water retention. That is why bodybuilders often turn to stronger tools like clen or orals such as winny or var when chasing single-digit levels. A full month of effort might get you close but probably not without the usual harsh methods.

Some steroids could support this. Tren acetate run for four weeks might allow it without much muscle loss but I still doubt you can avoid losing some tissue at that pace.

I guessed it was for a shoot. Pushing that hard in such a short window will likely cost more muscle than you want and the final look might disappoint you anyway. Could you move the shoot back another four to six weeks? You seem excited about the session and your current physique but rushing risks extra stress from constantly picking apart your own appearance instead of enjoying it.

The shoot is for a brand I work with and I will be shirtless so I want the lowest body fat possible.

For a drier appearance I will also do a carb depletion and reload in the last week plus a pump session with bands and weights right before the shoot. I plan to stop HGH a week out because it causes noticeable water under the skin.

You could also drop water in the 48 hours before the shoot. Look into bodybuilding show prep methods. It is not healthy but removing water can make you appear much leaner.

Cardio every day, lift heavy, eat plenty of protein, and stay in a calorie deficit. Tren can work if you are open to it and can source it. Good luck.

If you really want to try it, clenbuterol is an option. Some liquid versions avoid stomach issues from pills. It worked quickly for me and helped drop a few extra pounds each week. I am on week four now and just increased to 80 mcg.

Clen gave me awful side effects. I shook so badly I could barely use the toilet and it was constant. In my experience tren is actually milder on the system while also giving better muscle hardness and a dry vascular look. I do not understand how people tolerate clen. It was the worst thing I have ever put in my body even though some people seem to do fine with it.

That sounds rough. So far my only sides have been mild sweating. The resting heart rate increase was noticeable at first but I have adjusted and do not even notice it now unless I check with a monitor.

CopperAlder25archiveAug 17

I am concerned about the heart effects of stacking clen, yohimbine, or anything else that raises heart rate while I am on retatrutide. Combining those is generally not advised.

I have been on retatrutide for months, currently at 9 mg after dialing back from 15 mg to test if it still works. I started clen at 20 mcg three weeks ago and the heart rate issue settled within a week. Your choice.

I think you meant mcg. 20 mg would be lethal.

You could also sit in a sauna or do a hot yoga class in the 24 hours before the shoot. I do hot yoga every Saturday and drop up to 4 lbs of water. At 5 foot 7 and 143 lbs that is noticeable and I look quite shredded afterward.

No, my heart is made of brass. But yes it was 20 mcg.
