What to Buy Next?

Summary

What peptides or adjustments should a 40-year-old woman on retatrutide try next for weight loss?

The thread centers on a woman already using several compounds who wants guidance on adding or skipping items like AOD9604, GHK-Cu, and NAD while her scale has stalled. Participants mostly advise raising the retatrutide dose first, stripping back to fewer compounds, confirming a calorie deficit with high protein, and checking hormones before more purchases. Some suggest trying tirzepatide or cagrilintide for appetite control or exploring HRT instead of additional peptides.

What this discussion establishesWhere people disagree

Whether AOD9604 or tesamorelin is preferable for stubborn fat areas, and whether stacking many compounds helps or hinders progress.

Still open

Whether any specific addition or dose change will finally move the scale for this individual, and what her current BMR or full hormone panel shows.

Nothing here is advice.

I'm hoping for input on the next compound to try. Weight loss is the main goal for me as a 40-year-old woman. Right now I'm using 4 milligrams of Reta and may need to raise it because nothing is shifting on the scale. Weight has always been difficult even with clean habits. My current list includes 5 amino 1mq, mots, ss31, bpc, TA1, and selank. I'm looking at aod9604, ghk cu, kpv, L carnatine, epitalan, and NAD. Before spending more I'd like thoughts on what to hold off on or drop, or anything else worth considering.

I recently added a low dose of Reta on top of my usual Tirz because loss had stopped after 41 pounds. I also got some Cagrilintide to help with hunger and am thinking of using that instead of the current combo or swapping out the Reta. I'm planning to start at 10mg/.25mg and increase weekly toward 10mg/2mg. Curious what other approaches people use when the current meds lose their edge.

Just go higher on the dose and get more reta. The rest of those compounds are pleasant to have around and might help some people, but they lack solid evidence beyond anecdotes.

WarmAlder80archiveApr 7

I think too many peptides are being used together. When several hit overlapping pathways they can blunt each other's effects and raise inflammation, which works against the goal. A reset using just Reta at 4mg for two weeks, then adding MOTS-C plus NAD for another two weeks, would activate AMPK, support fat burning, lower inflammation, and improve mitochondrial function. After that, SS31 could be added for mitochondrial repair. If weight still isn't moving, AOD9604 might help with fat release. This assumes clean high-protein eating plus strength work and light cardio like walking after meals, plus enough calories around 1600-1800.

I already rotate what I use and only keep four going at once so I can tell what is doing what. I agree a reset makes sense, so I'll start Reta at five milligrams then bring in AOD. Giving the body a break from everything feels wise. I also take two full days off injections each week. Gym time is four days, calories stay near 1600 with 140 grams of protein, and processed foods are avoided completely. I've always carried extra weight but at least the shape is decent. Thanks for the input.

Newer is not automatically better. Reta does not suppress appetite as strongly as Tirzepitide. Since Reta has already been used, starting Tirz at 5 mg weekly should be fine. Only raise by 2.5 mg every four weeks if the scale is stuck, up to 15 mg. If loss is happening, even slowly, stay at the lowest dose that works so there is room to go higher later. Only after that would adding Reta or Cagri make sense.

Skipping straight to Reta without trying Sema or Tirz first now feels like a mistake because hunger is barely affected at all.

QuietSignal40archiveApr 7

Cagrilintide could be added to help with appetite.

QuietAlder20archiveApr 7

Tesamorelin has a stronger track record for reducing fat than AOD. I never noticed any change with AOD, though results vary.

That's the choice I'm weighing. From what I understand Tesa targets body fat in general, which would cover the legs and arms where I need it most, while AOD seemed more specific. If Tesa is actually better I can switch to that instead.

QuietAlder20archiveApr 8
↳ replying to @QuietSignal40

The way Tesa works on visceral fat is not fully clear, but it is established and approved for that use. Overall it acts as a growth-hormone secretagogue, prompting the body to release more of its own HGH, which supports general fat burning. Nothing in the research chemical space seems targeted at arm or leg fat specifically. AOD was studied heavily by pharmaceutical companies but was eventually dropped. I tried a kit anyway and saw no benefit, plus it tended to gel often.

It looks like a lot of peptides are being run together, which would make it hard to troubleshoot anything without removing most of them first. Instead of adding still more, check these basics: current diet and calorie intake to confirm a deficit, whether protein is at one gram per pound of body weight, how much resistance training or at least daily steps are happening, sleep quality, and water intake.

GreenMeadow54archiveApr 15
↳ replying to @WarmAlder51

Exactly. Tracking calories matters even if people resist it, because the medications only work inside a deficit and because learning sustainable eating habits is necessary long term. Moving toward less calorie-dense, minimally processed foods is also under-discussed but key, since the food environment changed more than our bodies did.

QuietSignal40archiveApr 15
↳ replying to @GreenMeadow54

I already eat very cleanly, lift four days a week, hit at least 100 grams of protein, and stay around or below 1600 calories. Sleep is the area I'm still improving. Food has never been the problem; I avoid sweets and anything processed because of a corn allergy. The body just tends to stay heavier regardless. I don't run everything at once either; bulk ordering happens mainly to avoid repeated shipping costs. Accountability is important, so I don't make excuses about fiber or small portions. Peptides are useful precisely because they can reveal what actually works for an individual when diet alone isn't enough.

I'm in a tough spot and must count on that forum member as my final option.

Many assume weight comes down only to diet and exercise, yet individual differences in calorie burn exist. While calories in versus out remains the core rule, GLPs may also influence metabolism in ways that aren't fully mapped. I've noticed days where intake was close to previous levels yet weight still dropped the next morning, especially near the prior dose time. Daily weighing over a long period makes those shifts obvious.

Four milligrams of Reta, four gym sessions, and 1600 calories a day with no movement on the scale? What was the last BMR reading?

KeenAlder60archiveApr 16
↳ replying to @WarmAlder80

AOD lacks supporting research; anecdotes split between those who claim it works and those who see nothing. The data leans toward the latter view. It is also unstable and gels unless reconstituted precisely. I tried it years ago with standard mixing and noticed no extra fat loss compared with not using it. Raising Reta remains the better move.

PatientFenwick91archiveApr 16

Before adding anything else, bloodwork focused on hormones, thyroid, and common deficiencies would be useful. At this age, HRT can deliver more noticeable changes than additional peptides. Men often call the Reta plus testosterone plus HGH combination ideal; for women over 40 the equivalent would be the estrogen/progesterone/testosterone combination.

QuietSignal40archiveApr 16
↳ replying to @WarmLedger35

The last BMR check was not very high and needs repeating. A previous doctor wanted calories at 1200 because the lack of loss was puzzling. Most of the weight sits in the hips and thighs, giving a curvy shape.

WarmLedger35archiveApr 16

Twelve hundred calories can work for a short aggressive cut provided protein stays adequate. I'm currently doing the same and reached 13.6 percent body fat in about six weeks.

QuietSignal40archiveApr 17
↳ replying to @WarmLedger35

It is manageable only briefly. In May the plan is 1400 calories for a month while dropping from 100 grams of carbs down to 50 to test whether that finally shifts things.

What does the e/p/t stack refer to? After a full year on GLP-1s and only 60 pounds lost at roughly two pounds per month, I'm still considered morbidly obese. Post-menopause and mildly hypothyroid, I've tried Sema, then Tirz for six months, then Reta for three months with almost no further scale movement, though other benefits are clear so stopping isn't an option.

Sixty pounds is still a major achievement.

EPT stands for estradiol, progesterone, and testosterone. Adding tiny doses of levothyroxine and liothyronine alongside that combination improved sleep, mood, and daily functioning noticeably for my wife.

SharpThistle74archiveMay 3
↳ replying to @BlueSignal97

The math shows 60 pounds in a year equals five pounds a month or about one pound weekly, which is a solid sustained rate. If progress has been steady without a stall longer than a month, continuing the same approach is reasonable.

Raising the dose to 6 mg stopped all eating, changed how food tasted, and brought nausea plus temperature sensitivity. Dropping back to 2 mg and adding MOTS-C plus ARA290 finally ended the plateau. Chills occur only occasionally now and eating or drinking is possible again, possibly helped by the every-other-day 5 mg MOTS-C schedule. Because of mild hypoglycemia, long fasts are not feasible and would also risk muscle loss anyway. Slow steady progress is acceptable. Food still tastes slightly off. Heat therapy like sauna use to induce sweating and clear pores might be worth trying for an additional reset effect.

CopperCompass12archiveMay 5

The same pattern appeared when titrating to 6 mg: near-total loss of interest in food, difficulty drinking enough water, nausea, and orthostatic hypotension that made standing quickly feel risky. The higher dose seemed to take over in an unpleasant way. That complete disinterest in eating felt strange and uncomfortable.
