I Injected 10 Peptides for 90 Days (Superhuman Experiment)
Jacob Nachinson — a 90-day, multi-compound self-experiment, fact-checked claim by claim: the bloodwork that never appears, the count that doesn't survive his own video, and the clinic link underneath it.

Featured — and checked. A 90-day self-experiment across four phases and more than a dozen substances, ending with a full protocol released “for viewers to replicate” — and a description whose first line is a membership ad for the telehealth clinic the presenter co-founded. We pulled the transcript and graded every load-bearing claim. The scorecard is below; the full working is in our claim-by-claim fact-check.
What this video covers
Nachinson structures 90 days into four phases — “repair,” “purge,” “rebuild,” and a final metabolic phase — cycling through SS-31 (elamipretide), KPV, ARA-290, a BPC-157/TB-500 blend, NAD+, FOXO4-DRI, epitalon, pinealon, thymosin alpha-1, and MOTS-c, alongside three oral supplements in the purge phase. He reports the outcomes as feelings, gym performance, boxing endurance, and Whoop wearable scores, and repeatedly invokes blood tests as the experiment’s scientific backbone. Mid-video, he recounts injecting the wrong vial — melanotan-2 instead of MOTS-c. The closing third releases his full protocol, framed as a takeaway for viewers who want to replicate the experiment.
Summary drawn from this video’s own transcript (banked in our research library, pulled 2026-11-09). The video’s claims are the speaker’s — attributed, not endorsed. This site publishes no dosing, protocol, or sourcing information — including his.
Key points, in the speaker’s own framing
- The promise: 90 days to “superhuman levels of output” across muscle, fat loss, sleep, skin and hair, driven through mitochondria.
- The evidence offered: how he feels, dumbbell numbers returning toward a previous peak, boxing endurance, and Whoop recovery scores — “cracked the code on Whoop recovery.”
- Blood tests are invoked throughout (“I’m getting blood tests all along the way”) — and the video ends with the remaining bloodwork still to be taken. No lab result appears.
- FOXO4-DRI, which he concedes has “no human trials in history,” is credited with destroying “nearly all” senescent cells in his liver, lung, kidney, heart and muscle.
- He acknowledges placebo once, in passing — “whether it’s the peptide or placebo or whatever I’m enjoying it” — and never returns to it.
- His results benchmark, mentioned in passing: “best results since I very first started TRT.”
We checked this video
Our verdicts, in plain language — the same scale as our other scorecards. Supported = the record backs it. Mostly right = true with a correction attached. Overstated = a real thing stretched past its evidence. Unsupported = no source we could find backs it. Wrong as stated = the record says otherwise.
| The video’s claim | Our verdict | Why, in one line |
|---|---|---|
| He injected “10 peptides” | Wrong as stated | His own video names 11 injectable compounds — plus a 12th substance, melanotan-2, injected by accident. The title’s number survives only by quietly excluding entries. The count audit |
| Blood tests ran “all along the way” as the experiment’s backbone | Unsupported | The video ends with “I still have to take my remaining blood work.” No lab value appears in the video or its description — the description’s only link is his clinic’s membership page. |
| The results were “superhuman” | Unsupported | The entire dataset is self-report, a wearable’s proprietary scores, and gym numbers returning toward a previous peak — not past it. Nothing superhuman was measured; almost nothing was measured. |
| His flagship compound’s amount | Wrong as stated | He states one daily amount for SS-31 in the day-1 segment and a different one in the final recap — and the daily figure times the stated phase length does not equal the total he states. Three numbers, no two agree. (Figures quoted only inside the fact-check’s inconsistency finding.) |
| SS-31 is an FDA-approved drug | Mostly right | Elamipretide (Forzinity) won accelerated approval on September 19, 2025 — for Barth syndrome, a rare disease, on an intermediate endpoint. Its larger trials in heart failure and other conditions missed their primary endpoints. Gray-market “SS-31” is not the approved product. |
| FOXO4-DRI destroyed “nearly all” senescent cells in five organs | Unsupported | No instrument or clinical biomarker exists that can measure organ senescent-cell burden in a living human. The compound has zero human trials; the mouse studies established clearance by dissecting tissue. |
| MOTS-c transformed his energy and focus | Unsupported | No completed published human trial of MOTS-c exists; FDA has stated it identified no human exposure data. His account is an anecdote told while he was simultaneously changing sleep, sunlight, phone and training habits. |
| Epitalon lengthens telomeres | Overstated | The claim traces to one research institute’s program; the most-cited long-term human study used epithalamin, a different substance. No human trial has measured telomere lengthening in a treated person — and he measured none. |
| Pinealon supports brain and chromosomes | Unsupported | Its entire literature is cell cultures, rodent models, and computer simulations, all from the originating institute or collaborators. The one study testing it on pineal cells came back negative. |
| ARA-290 as a “repair phase” compound | Mostly right | Real science, wrong context: ARA-290 has genuine small Phase 2 data — in sarcoidosis nerve damage, a decade old. Its developer folded and the last trial was terminated when the drug supply expired. It says nothing about healthy lifters. |
| Thymosin alpha-1 as an immune “debris cleaner” between phases | Overstated | A real drug — approved in 35+ countries as Zadaxin for hepatitis B and vaccine support. Not FDA-approved in the US (the advisory committee voted 17–4 against compounding-list inclusion in December 2024), and no regulator anywhere recognizes a “debris-clearing” use. |
| “mTOR is catabolic to muscle growth” | Wrong as stated | mTOR signaling is the central anabolic pathway in muscle biology — it drives muscle protein synthesis. The mechanism is inverted, in the video’s science segment, with total confidence. |
| Whoop recovery scores prove the peptides worked | Overstated | Whoop’s raw heart-rate-variability sensing is decent at rest; its Recovery score is a proprietary composite never validated against any gold-standard measure of recovery — and HRV moves with sleep, alcohol, illness, training load and expectation. |
| The peptides caused his results | Unsupported | He ran the 90 days on testosterone replacement therapy while changing training, diet, sleep and habits phase by phase, recovering from a heavy-drinking past. Every reported outcome is fully explained without any peptide doing anything. That doesn’t prove they did nothing — it proves the video cannot tell, and a video that cannot tell should not conclude. |
| He injected the wrong vial mid-experiment | Supported — his own account | Melanotan-2 instead of MOTS-c, from look-alike vials, told as a joke. It is the most honest moment in the video — and the direct answer to its closing invitation to replicate. |
The argument, in context
This video is the influencer lane’s standard product in its most polished form: a comic-book promise, a lab-coat structure, a protocol as the payload, and a clinic as the destination. Compare AsapSCIENCE’s BPC-157 video — the critics’ version of certainty — and grade both by the same standard: what was measured, what was shown, what is being sold.
