Microdose, BMI 18

Try adding some resistance work and maybe a few supplements; staying too low on BMI gets riskier with age.

Focus on training the parts that still feel good, especially the legs if they allow it. The big muscles below the waist deliver broad health payoffs when worked. Begin gently to stay safe, then increase effort over time. Check Dr. Ford Brewer on YouTube for extra detail.

Fine as long as there is no eating-disorder history and weight stays monitored.

Using tirz at a BMI of 18 carries real risks; 18 sits at the edge of most anorexia cutoffs, so deliberately getting leaner than that is rarely wise. The microdose angle is somewhat reassuring, yet careful weight tracking and readiness to stop if the scale drops further will probably be needed.

Other peptides exist for inflammation if that is the main target.

What goals are you chasing with the GLP-1? Beyond the weight-loss and appetite effects it was made for, what improvements do you hope to see, and is there a more direct route to those same results?

What is your body fat percentage?

At a BMI of eighteen there's really no point in taking tirz.

BMI 18 is already concerning. Any eating-disorder history would clearly argue against it. At that level there cannot be much muscle, and muscle matters most for staying active into the fifties and beyond; resistance training cannot be stressed enough. Tirz is usually the pick, but reta might let a higher dose be used without as much appetite drop. Skeptical that under 1 mg of tirz will do much for cartilage regrowth, and any inflammation relief may stay modest.

I've started rotating my sessions between klow and kpv/ghkcu as the alternative.

Not sure of height, but that BMI is low for an average adult. Other options exist for osteoarthritis and type II collagen.

What are your goals, if not weight loss?

I am F49 with knees that complain a lot. Muscles must be protected when using GLP-1s. Must. Muscle is already hard to gain at this age, and these drugs tend to strip it unless protein stays high and resistance training is consistent. Have seen nothing claiming tirz regrows cartilage; would have started yesterday if it did. With arthritis, less inflammation mainly means less ongoing breakdown, which is still helpful. Faster recovery and quicker adaptation to new movement are realistic; actual cartilage regrowth probably is not. The real danger for older adults is not the initial fall or break but the inactivity that follows, leading to lost muscle and lasting mobility trouble.

During my transition into menopause I noticed that carrying a few extra pounds actually helped me feel better.

Also a bit more context on GLPs and cartilage regeneration. Cartilage apparently has GLP-1 receptors, so joint improvement may not come only from less body weight; actual regeneration could occur. One MD microdoses for the non-weight-loss effects.

That word basically signals it keeps the condition from advancing any further. The shrug shows my doubt, yet easing the swelling still amounts to a major plus for OA.
