Thanks but any ideas on where to purchase? Perplexity Pro… Haven’t used it before but snds powerful.

I would say some peptide that act on parts of the hpg axis continously lead to desentization. GnRH agonists continously stimulate the pituitary, which leads eventually to a drop on testosterone. Some of them are used for chemical castration.

Did you mean GB-115, or BPC-157?

After reading what BPC-157 can possibly do I’m definitely interested in it’s possibilities. I had a hip resurfacing done here in Hong Kong and the quack doctor sold me up right along vital nerve and or muscle which created chronic pain to this very day as I write this note. It’s been going on for 6 years now and I tried everything under the sun and I do mean everything. So please tell me how I would get some more info into obtaining this BPC-157. I haven’t checked the forums for any testimonials.

DSIP, Epitalon and Endoluten have been mentioned as being useful for sleep. I’ve tried a few sleep drugs, but don’t like the side effects. So, I always go back to doxylamine or diphenhydramine, two OTC drugs associated with Alzheimer’s or dementia of other types. Has anyone had a regular good experience related to better sleep with any of these three peptides/bioregulators or any others? By regular I mean for weeks and months, not just a few days. Thanks.

Was that inferred by only creatinine, or did you have any other tests to support improved kidney function? A 30 point increase is really very remarkable and I’d love to share this with people.

DSIP stands for Delta Sleep Inducing Peptide. It’s not a sleep aid, it does not make you drowsey or sleepy, it has no aftereffects like sleep inducing products (drugs or supplements) often have. It seems to only do 1 thing, increase the time in Delta or Deep sleep. 4 people (my wife and I) and 2 others have done sleep tracking before and after as we’ve all found a significant increase in deep sleep. Mine went from a bit over an hour to nearly 2 hours consistently.

It does seem to be individually dose dependent. For me, 0.3mg per night does the trick, 1 of my friends found that 0.45mg was what he needed, another was good with 0,25. A bit of experimentation over the course of a month with a sleep tracking app helps find the individual dose.

I do like peps with easily measurable results :slight_smile:

For us zero noticeable sleep benefit from Epitalon, but that was before we were tracking sleep. It may be dose or timing dependent and a tracker would help to understand if there is a benefit. Since I’m already a super sleeper I’d probably not see much benefit anyway.

As we both take CJC 1295 and Ipamorelin 5 nights a week and were doing this for nearly 2 years prior to adding DSIP to our nightly routine, I’d say the increasing hGH was not that helpful in improving our sleep while many people swear by it for this specific effect.

Look up scent benefits while sleeping for the possibility of reducing risk to dementia. Stimulating the olfactory system while sleeping may provide a benefit. I would have to balance the benefit vs the downside of “flavored” air causing other issues.

Zero sleep benefits from DSIP or epitalon for me. Some users on the peptide forums swear by one or both, others like me get nothing.

I did a cycle of epitalon and I’d even say my sleep was worse on it lol. I did dose it very high however. In the future I’d do smaller doses.

I’ve had the same experience.

Best things for me so far have been reducing caffeine, having caffeine earlier, making sure I’m not exposed to allergens and doing exercise earlier in the day.

No, just egfr based on creatinine levels both before and after being on retatrutide.

Approximately 200mcg per spray (20mg of active compound per bottle) At 6mg per day this doesn’t seem feasible.

Supposedly more bioavailable nasally. I notice a little bit but not that much when using.

A recent short YouTube video from Dr. Matt Kaeberlein. I won’t summarize it because it is quite short. And yes, I tend to be an early adopter of “shiny objects.”

Expresses my thoughts exactly, especially after the fact that I tried several injectable peptides over a period of months without any subjective or measurable benefits from most.
The exceptions were tirzepatide and N-acetyl semax nasal spray.

Tired many but only a few peptides had noticeable impacts:

Tirz and Reta - major impacts visibly, on scale, in many labs; which led me and many others to hope other peptides would have similar or even part of the degree of impact … none have come close but a few have been noticeable.

Semax - initially impact was more significant, you simply notice it. Perhaps not as much as anticipated from that initial feeling though.

Tesamorelin / Ipamorelin - measurable labs and waist size reduction. Dexa scans not close enough to correlate with this cycle but potentially visceral fat reduction related to this.

GHK-cu - topically I’m skeptical but it doesn’t hurt, injected give minor skin improvements but not noticeable reduction in loose skin.

Maybe some benefit from TA-1 (family all got flu and colds but I stayed health), BPC and TB4 (hard to tell if injured would have healed as fast or recovery as fast if done without them - didn’t resolve old injuries).

Over 10 other peptides and SARMS and NAD: nothing noted from labs, scale, or subjective feelings.

I wasn’t sure where best to post this.
But this is an intriguing longevity protocol, that if valid, puts rapamycin to shame.

Hi, I typically use this protocol here Using AI for Health and Longevity and Research - Your Favorite Prompts - #17 by RapAdmin

do evaluate a transcript of the video, to save time and to fact-check the claims.

Here is the result from ChatGPT:

A. Executive Summary

This episode features Dr. Bill Lawrence presenting long-awaited results from an 8-year telomere study and a 5-year epigenetic (DNA methylation) study evaluating Russian-discovered bioregulator peptides. Trained directly under Professor Vladimir Khavinson, Lawrence situates his work as a U.S.-based confirmation of decades of Soviet and Russian clinical research originally developed for military, spaceflight, and occupational health resilience.

Bioregulator peptides are short, organ-specific amino acid sequences derived from animal tissues that allegedly home to corresponding human organs, modulating gene expression, DNA repair, and tissue regeneration. Lawrence argues they act as normalizers, not stimulants—restoring youthful cellular function rather than boosting or suppressing systems.

Central claims include:

  1. Dramatic mortality reductions (up to ~50–60%) in elderly populations using pineal and thymus peptides alone;
  2. Organ regeneration, including retinal tissue in degenerative eye diseases;
  3. Biological age reversal or deceleration, measured via telomere length and increasingly granular epigenetic clocks assessing up to 19 organ systems.

Lawrence emphasizes that pineal and thymus peptides consistently outperform others, calling them foundational to all protocols. He reports that oral natural peptide extracts, while slightly less potent than injectable organ extracts, retain ~90% of their long-term telomere effects and are suitable for multi-year use.

Importantly, observed benefits reportedly require long durations (1–4 years), contrasting with fast-acting synthetic peptides. Lawrence frames the intervention not as “anti-aging” but as system-wide repair, aligning with Khavinson’s view that aging cannot be reversed wholesale but can be profoundly modulated at cellular and epigenetic levels.


B. Bullet Summary (15–18 bullets)

  • Bioregulator peptides originated in Soviet military and space medicine during the Cold War.
  • Peptides are short amino acid chains (2–4 AAs) derived from specific animal organs.
  • These peptides are claimed to be organ-specific via receptor “docking” mechanisms.
  • Pineal and thymus peptides were the first discovered and remain the most impactful.
  • Russian trials showed ~50% reductions in mortality using only pineal peptides.
  • Combining pineal + thymus peptides further reduced mortality in older cohorts.
  • Effects were observed even when peptides were administered for only ~3 years.
  • Lawrence launched U.S.-based confirmation studies beginning ~2017.
  • Biological aging was assessed using telomeres and DNA methylation clocks.
  • Epigenetic testing evolved from single-age outputs to multi-organ aging profiles.
  • Newer labs claim direct measurement (not prediction) of organ-specific aging.
  • Protocols are adjusted based on accelerated aging in specific organs.
  • Oral natural peptide extracts are ~90% as effective as injectable extracts long-term.
  • Synthetic peptides act faster but are less suitable for long-duration longevity goals.
  • Peptides appear to normalize function rather than stimulate or suppress systems.
  • Claimed mechanisms include restoration of DNA repair systems.
  • Reported organ regeneration includes retinal tissue in degenerative eye diseases.
  • Meaningful results typically require 1–4 years of consistent use.

D. Claims & Evidence Table

Claim Evidence Presented Assessment
Pineal peptide reduces mortality by ~50% Russian elderly cohort studies (12-year follow-up) Speculative (extraordinary effect; limited independent replication)
Pineal + thymus peptides reduce mortality to ~33% in ages 75–89 Russian “old people” study Speculative
Bioregulator peptides are organ-specific Animal-derived peptide homing observations Weak–Speculative
Peptides restore DNA repair systems Khavinson-published studies (not detailed here) Weak
Oral peptides are ~90% as effective as injectables Internal telomere comparisons shared verbally Unsupported (no published data shown)
Retinal degeneration can be reversed Visual field imaging examples; anecdotal cases Weak–Speculative
Telomere length increases after peptide use Lawrence’s 8-year study (data not shown yet) Speculative
Epigenetic age can be reversed or slowed 5-year DNA methylation data (not shown) Speculative

E. Technical Deep-Dive (Relevant)

The proposed mechanism centers on epigenetic modulation and DNA repair normalization. Khavinson’s hypothesis suggests peptides bind nuclear DNA regulatory regions, influencing transcription and improving fidelity of DNA repair machinery. Improved repair theoretically reduces mutation burden, stabilizes telomeres, and restores tissue-specific protein expression. This places peptides upstream of many aging hallmarks—but this remains mechanistically under-characterized in Western molecular biology terms.


F. Fact-Check of Important Claims

  • Mortality reductions of 40–60%: These figures far exceed effects seen with any validated longevity intervention (e.g., statins, caloric restriction mimetics). Independent replication outside Russia is lacking.
  • DNA repair “restoration”: No widely accepted evidence shows peptides can globally reset DNA repair systems in humans.
  • Retinal regeneration: Conflicts with current ophthalmologic consensus; extraordinary claim requiring randomized controlled trials.

Bottom line: The claims are biologically intriguing but extraordinary, and currently rest on limited-access Russian literature, unpublished data, and anecdote. Independent replication, peer-reviewed U.S./EU trials, and mechanistic validation are essential before acceptance into evidence-based longevity medicine.

I’m more inclined to think of most if not all of the “bioregulators” as a scam, but if future research proves differently then I’ll be happy to change my mind.
