- 17:39Reconstituted retatrutide vial lifespanSteve says hCG degrades quickly but retatrutide and similar peptides seem more stable. He suggests picking a vial size you can finish in roughly 30 days.
- 21:46Cagrilintide and retatrutide experienceHe describes feeling lethargic on retatrutide plus cagrilintide and quitting after about three weeks. He mentions eloralintide is on its way to him.
- 26:07Mirabegron dosing for fat lossSteve says he used 150 mg per day and suggests starting lower. He says timing matters little because of the long half-life.
- 28:27SLU-PP-915 versus SLU-PP-332He says 915 is claimed to be more orally bioavailable than 332 and that he is waiting to try it. He says the differences between the two are not well researched.
- 56:09ATX-304, BAM15 and DNP comparedSteve ranks ATX-304 as the mildest uncoupler, then BAM15, then DNP. He describes using a topical BAM15 spray on his chest.
- 1:35:56How to dose SLU-PP-332He says there are no hard rules, advises starting low and building up, and says to stop if blood work looks bad. He reports lowered IGF-1 on 400 milligrams.
- 1:37:10Retatrutide and PEG-MGF blendSteve describes running a blend of retatrutide and PEG-MGF and says it is too early to know whether it makes a difference.
- 1:40:45Oxidative stress around surgeryHe suggests glutamine, glutathione and SS-31 around surgery and says a varicocele should be fixed before starting fertility drugs.
- 1:52:11Berberine with retatrutideAsked about adding 500 mg berberine to 1 mg retatrutide, Steve says he is not against it and describes how he takes berberine himself.
What the video says
This is a live Friday Q&A hosted by Steve, who answers member and super chat questions. Most of the two hours is about anabolic steroids, hCG dosing, blood work, sleep, family life and promotions. The peptide and fat-loss material is scattered through it, so the chapter list helps if you only want that part.
The longest peptide segment covers cagrilintide. Steve says he tried it with retatrutide, at 1 milligram of retatrutide three times a week plus half a milligram of cagrilintide three times a week. He says he became very lethargic, needed extra carbs to cope, and dropped it after about three weeks. He notes that others respond well and that amylin agonists seem to work at lower milligram doses than GLP-1 drugs. He also mentions an upcoming eloralintide sample and says he will stop quickly if it makes him lethargic again. On retatrutide vials, he suggests choosing a size you can finish in about 30 days.
Steve also covers other fat-loss and performance compounds. He describes taking mirabegron at 150 mg per day and says he has heard of people on 200 mg, with 50 mg twice daily as a starting idea. He ranks ATX-304, BAM15 and DNP from mildest to most aggressive uncoupling, and says a topical BAM15 spray worked on his lower chest without raising his body temperature. He compares SLU-PP-915 with SLU-PP-332 and says he is waiting on a sample, and he discusses SLU-PP-332 dosing from micrograms to 400 milligrams.
Later he describes running a compounded blend of retatrutide and PEG-MGF, which he calls metatrutide, and says it is too early to judge because he has only just returned to the gym. He also lists glutamine, glutathione and SS-31 for managing oxidative stress around surgery, and mentions pairing topical BAM15 with NAD+. Everything is anecdotal and framed around his own use and his sponsors' products.
On each compound
Cagrilintide21:46
Steve says he used half a milligram three times a week alongside retatrutide and felt very lethargic, so he stopped after about three weeks. He adds that some people respond well and that amylin agonists seem to work at lower milligram doses than GLP-1 drugs.

Steve says retatrutide seems stable enough that a vial finished within about 30 days should be fine. He describes taking 1 milligram three times a week, and says it could lower hematocrit when that is raised by sleep apnea linked to excess weight.

Steve describes running a retatrutide blend that includes PEG-MGF at 2 milligrams per vial. He says he has not seen much from PEG-MGF in the past and cannot yet tell whether it adds anything.

Steve says he used SS-31 before surgery, along with glutamine and glutathione, and recommends it for managing oxidative stress afterwards. He also says people may need SS-31 and magnesium first if SLU-PP-332 does nothing for them.
See how your DNA reads SS-31NAD+57:23
Steve says he combines topical BAM15 with NAD+ and 5-amino to keep fat metabolism going in fat tissue. He also lists NAD+ among the supplements he would use at 90 years old.

- All peptide comments are one person's experience, with no control group, blinded comparison or blood data shown for these compounds.
- Steve had not yet tried eloralintide, ATX-304 or SLU-PP-915 when he spoke, so the video gives no firsthand results for them.
- The claims about SLU-PP-915 bioavailability and its organ selectivity are stated from memory, and he says he has not researched them in depth.
Questions this video answers
How does Steve dose mirabegron for fat loss?
Steve says he took 150 mg per day and knows people taking 200 mg, and that a lighter person could start at 100 mg. He suggests 50 mg twice daily for a week before increasing, and says timing is mostly irrelevant because of its long half-life.
How does Steve rank ATX-304, BAM15 and DNP?
He says ATX-304 is the mildest and causes the least oxidative stress, BAM15 sits in the middle, and DNP is the most aggressive for similar fat loss. He had not yet tried ATX-304 when he said this.
What happened when Steve combined cagrilintide with retatrutide?
He says he became very tired, ate more carbs to compensate, and quit after about three weeks because the extra food defeated the purpose. He says others get stronger appetite suppression from the combination.
What does Steve say is different about SLU-PP-915 compared with SLU-PP-332?
He says published evidence suggests 915 is more orally bioavailable, while 332 is not, though people still report effects from 332. He had not yet tried 915 and says any other differences are unclear to him.
How long does Steve say a reconstituted retatrutide vial lasts?
He says a general rule is to finish a vial within about 30 days of reconstitution, and that even six weeks should probably be fine. He suggests choosing a vial size that fits that window.
