"Vigorous Steve reported in the source video: "I would do 1 mg to 2 mg tesamorelin before bed, ideally combined with CJC or ipamorelin" - describing his personal protocol for maximizing growth hormone secretion. Reported observation only; not medical advice."
"I did see the study that was showing that tesamorelin does increase insulin resistance for a temporary period of time, but in the long run it goes back down and levels out at baseline."
"we're using SS-31, tesamorelin, um high dose methylene blue like which you can see from these doses."

"for on days off for some reason I sleep better on Teslan not sure if that's cuz of the natural pulse but I just do for some reason I use it I don't know."
"I never really got much sleep out of Tesamorelin or CJC or Ipamorelin, but on growth hormone I sleep like a baby."
"According to the guest speaker, the suggested timing protocol involves taking tesamorelin roughly two hours after the last meal (e.g., last meal at 8:00 p.m., tesamorelin at 10:00 p.m.), followed by exogenous growth hormone about an hour later. The guest reported that this spacing is intended to avoid blunting..."

| Speaker | Source | Timestamp | Protocol | Evidence |
|---|---|---|---|---|
| Nick | Growth Hormone Vs Peptides - It's NOT even close! | 00:13:55 | Nick reported visceral fat reduction visible within 8-12 weeks; cycle structure similar to other GHRH analogs but with more flexibility for longer durations | anecdotal |
| Hunter Williams | The BPC-157 Masterclass | Complete Users Guide (2026) | 00:24:13 | No specific dose given; discussed as a GH peptide that may be added after BPC receptor upregulation, commonly with GH secretagogues before bed. | anecdotal |

| Hunter | Saturday Morning Coffee Talk 6/6/26 | 00:42:51 | Hunter compares 1 mg tesamorelin to 2 IU HGH as potentially producing similar total IGF-1 around 300 but different free IGF dynamics. | anecdotal |
| Vigorous Steve | Oral Vs Injectable SLU-PP-332, Ideal GH To Test Ratio, High... | 00:36:12 | 1-2 mg tesamorelin before bed, ideally combined with CJC-1295 or ipamorelin. FDA-approved dose 2 mg/day for visceral fat reduction. | anecdotal |
| Dr. Michael Müller | Doctor's Longevity Hack. Retatrutide, Tirzepatide, Peptides Fix? | 00:08:18 | Dr. Michael Müller reported using tesamorelin to support growth hormone release at night while sleeping; no dose was specified. | anecdotal |
| Vigorous Steve | GH Secretagogues Vs Real GH, Managing Estradiol On Cycle,... | 01:48:57 | 2mg tesamorelin + 500mcg ipamorelin together every single day for visceral fat reduction; equivalent cost to 5-6 IU generic GH | anecdotal |
| VS | Are Secretagogues Actually Worth It? Or Should You Just Go With HGH? | 00:04:36 | VS reported using 1-2 mg subcutaneous twice daily; some users run up to 3x daily. Cost: ~$10/day low-end to $36/day high-end | anecdotal |
| Nick | The Fastest Way to ACTUALLY Reverse Insulin Resistance in 2026 (Not... | 00:05:37 | Nick reported using 1 mg daily before bed on an empty stomach, running cycles of 12 to 24 weeks with no taper. | anecdotal |
| The Peptide Podcast | Tesamorelin Dosing-A Beginner-Friendly Deep Dive | 00:03:51 | Anecdotal reports describe split dosing: part of the dose in the morning and part at night, intended for continuous growth hormone stimulation. Some users report this approach was intended to support fat loss during the day and recovery at night. However, higher risk of side effects has been reported (joint pain, swelling, glucose changes), and healthcare consultation is recommended before use. | anecdotal |
| The Hunter Williams Podcast | The Tesamorelin Masterclass | Complete User's Guide (2026) | 00:13:24 | Users report an optimization dose of 1 mg daily, with some smaller women reportedly using 500 mcg daily. Reported applications include general optimization, cognitive support, sleep, and body composition support. Tesamorelin is known to stimulate IGF-1 production through GHRH signaling; users report observing IGF-1 increases in the 40-70% range. | anecdotal |
| The Peptide Podcast | Tesamorelin, Food Timing, and Why Consistency Actually Matters | 00:02:30 | The source (Host in bBRtmCfmwNo) described the following tesamorelin dosing protocol: morning administration on an empty stomach, waiting 30 to 60 minutes before eating; optionally including fasted cardio (walking, light cycling, low-intensity exercise) during that window before breakfast. | anecdotal |
| Trensparent with Nyle Nayga | Andrew Berry: New Age PED, Insulin, & Peptide Approach to Growth | 00:15:28 | 1 mg tesamorelin taken 2 hours after last meal (e.g., last meal 8pm → 1mg at 10pm), then ~1 hour later take GH at half the normal dose (e.g., reduce from 8 IU to 4 IU). Used during Phase 1 'restore and regenerate' 4-week post-prep protocol. | anecdotal |
| Dr. Jones DC | You're Injecting Tesamorelin WRONG! Doctor Explains How to Inject Tesamorelin | 00:04:13 | Inject subcutaneously into fatty tissue, commonly abdomen one or two inches from the belly button. Rotate injection sites; use a short fine insulin needle, pinch a little, angle, and push slowly. | anecdotal |
| Dr. Jones DC | The Perfect Tesamorelin Timing #biohackingtip #metabolichealth | 00:00:02 | The speaker reported taking Tesamorelin before bed, fasted 2 to 3 hours after the last meal. | anecdotal |
