- 0:00Why he made this listJoseph says he would change several things about his GLP-1 start, drawing on his own mistakes and those of his patients.
- 0:28Baseline DEXA scan and labsHe says to track body composition and metabolic labs, not just weight. He suggests labs every 3 to 6 months and a DEXA scan every 2 to 3 months.
- 1:37Resistance training from day oneJoseph says reduced appetite can lead the body to break down muscle. He says he relied on cardio and lost muscle, and recommends weights 2 to 3 days a week.
- 2:23Making protein non-negotiableHe describes eating low-effort, low-calorie foods and losing muscle. He tells patients to aim for about 1 to 1.2 g of protein per kilogram, or 120 g to 140 g daily.
- 3:10Planning for side effectsHe says nausea, constipation and fatigue are predictable and recommends preparing for them in advance. He mentions magnesium citrate or Miralax, ginger or peppermint tea, and hydration and electrolytes.
- 3:35Start before you feel readyJoseph says he delayed the gym while waiting to lose weight first. He argues that patients who do well start imperfectly and adjust using their data.
- 4:20Layer peptides instead of stackingHe says adding several peptides at once made it impossible to tell what was working. He advises waiting 2 to 3 months on a consistent GLP-1 dose before adding others.
- 5:13Body image and mental healthHe says weight loss did not automatically change how he sees himself. He mentions therapy, journaling and mindfulness as approaches his patients report using.
What the video says
Dr. Kevin Joseph, a physician who says he has lost over 150 lb, looks back on his two years on GLP-1 medication and lists seven things he would do differently. He frames them as mistakes he made himself and ones he sees repeatedly in his patients. The video is mostly general weight loss coaching rather than a peptide deep dive.
He starts with data. He says weight alone does not show whether someone is losing fat, muscle or water, so he recommends a DEXA scan and baseline labs such as A1C, fasting insulin, a lipid panel and thyroid function. He suggests labs every 3 to 6 months and a DEXA scan every 2 to 3 months. He then argues for resistance training from day one and a firm protein target, saying that eating very little and doing mostly cardio cost him muscle. For protein he tells patients to aim for about 1 to 1.2 g per kilogram, or 120 g to 140 g a day. He also describes a side effect plan covering constipation, nausea and hydration.
The peptide-specific advice comes in the middle. Joseph says one of his biggest early mistakes was adding several peptides at once while new to GLP-1 treatment, naming tesamorelin, ipamorelin, BPC-157 and TB-500. Because he was losing weight with all of them in his body, he could not tell which one was responsible. His suggestion is to start with one variable, learn your response to a consistent dose, and wait more than 2 to 3 months on a stable GLP-1 dose before adding other weight loss peptides.
He closes with a mindset section. He describes ongoing body dysmorphia, says patients have found therapy, journaling or mindfulness useful, and encourages starting imperfectly instead of waiting to be ready. Everything here is his personal and clinical opinion, offered as reminders rather than a protocol.
On each compound
Tesamorelin4:20
Joseph names tesamorelin among the peptides he took alongside a GLP-1 early on. He says taking them together made it unclear which compound was driving his weight loss.

Joseph lists ipamorelin as one of several compounds he combined with a GLP-1 too early. He says he could not tell what was causing his results.

Joseph mentions BPC-157 as part of the group of peptides he stacked at once. His point is about attributing effects, not about what it does.
See how your DNA reads BPC-157TB-5004:20
Joseph includes TB-500 in the set of peptides he used at the same time as a GLP-1. He says the overlap made it hard to isolate any one compound's effect.

What this video doesn’t settle
- It is one physician's personal experience and patient observations, with no data or control group presented.
- The advice to wait 2 to 3 months before adding peptides is his own rule of thumb, not backed by any cited evidence.
- The video names tesamorelin, ipamorelin, BPC-157 and TB-500 only as examples and says nothing about their effects, doses or safety.
Questions this video answers
Should you add other peptides while starting a GLP-1?
Joseph says he regrets adding several peptides at once while new to GLP-1 treatment, because he could not tell which one was working. He suggests starting with one variable and waiting more than 2 to 3 months on a consistent GLP-1 dose before adding others.
What baseline tests does Dr. Kevin Joseph recommend before starting a GLP-1?
He recommends a DEXA scan for body fat, lean muscle and visceral fat, plus labs such as A1C, fasting insulin, a lipid panel and thyroid function. He suggests repeating labs every 3 to 6 months and the DEXA scan every 2 to 3 months.
How much protein does Dr. Kevin Joseph recommend on a GLP-1?
He says there is no concrete rule, but he usually tells patients to aim for roughly 1 g or 1.2 g per kilogram of body weight. For simplicity he often gives a set target of 120 g to 140 g a day.
Why does Joseph say to lift weights while on a GLP-1?
He says reduced appetite means people eat less and the body can break down muscle for energy. He recommends resistance training from day one, saying even 2 to 3 days a week helps preserve lean muscle mass.
