Stacks, scored.
Peptide, biohack, and longevity stacks lifted from Twitter and Reddit, then graded across 5 goal axes — by editors who aren't afraid to say a dose is reckless.
Latest stacks
u/ConclusionInfinite95 heavy metabolic stack: Reta + Tesamorelin + MOTS-c + SS-31 + KLOW
The author asks the three questions that actually matter and most peptide-stack posts don't. Are Reta and Tesa redundant on visceral fat? Does MOTS-c on top of Reta's HR bump push cardio too far? Does Tesa-driven insulin resistance get hidden by Reta and MOTS-c's opposing glucose effects? Real, sharp concerns. The stack is mechanistically coherent: Tesa at the exact FDA-approved Egrifta dose, KLOW at 4mg/day (high end), MOTS-c pre-workout at high but defensible volume. Reta sourcing remains the structural risk.
@brentlajeunesse 'I would never inject this, but if I did' stack: Reta + KLOW + Selank + Semax + HCG + MOTS-c
The 'I would never inject Chinese research-grade material, but if I did' framing is the peptide community's standard legal fiction. It's also self-aware: author openly acknowledges the sourcing reality most peptide influencers paper over. The stack itself is community-standard: Retatrutide as the metabolic backbone, KLOW for recovery, Selank + Semax for cognition, HCG for HPG-axis (implying androgens not listed), and MOTS-c. No doses given, which keeps this in C territory. The 'drop your stack below' close makes this a community thread-starter, not a protocol.
@morellifit full peptide stack: AM repair + Epitalon/Pinealon + DSIP + Tirz microdose + exercise mimetics
The best-disclosed stack on the site so far. Morelli has doses, timing, cycling logic, and explicit n=1 learning ('ran DSIP daily, got groggy, now I pulse it'). He treats Tirzepatide as a fat-loss backbone and layers SLU-PP-332, 5-amino-1MQ, and MOTS-c with intentional sequencing. Three concerns. The Tirzepatide microdose (1.5-2.25mg/wk total) is below the trial starting dose. SLU-PP-332 and 5-amino-1MQ are preclinical-only with essentially zero human data. And 2mg/day TB-500 is daily continuous use of a compound typically loaded weekly.
@edgaralandough 'apparently this just works' fundamentals stack — May 2026
This is the load-bearing 90% of any health stack — sleep, 230g protein, lifting six days, cardio, creatine, magnesium/glycine, no alcohol, no scrolling — at calibrated doses where doses are listed. The author is right that it works; the framing as a discovery is the funny part because nothing here is novel. Held back from an A by two opaque lines: 'full vitamin stack' is bounded but unspecified, and 'peptides' could be anything from a daily 250mcg BPC-157 oral to a 9 IU GH protocol, and the analysis changes entirely depending on which.
@ZachMcGrew 11-compound kitchen-sink peptide stack — May 2026
Eleven compounds, several at supratherapeutic doses, with the 9 IU/night GH crossing from anti-aging-clinic territory squarely into bodybuilder territory. The HCG 250 IU EOD strongly implies undisclosed TRT underneath, which makes the stack as listed incomplete. There's real thought in the composition — VIP, Mots-C, Semax/Selank are coherent picks — but the doses are aggressive across the board, the growth-axis stack (9 IU GH + IGF-1 LR3) is the wrong direction for longevity, and no monitoring framework is mentioned for any of it.
@legdaydaddyy retatrutide + KLOW + NAD+ stack — May 2026
Three items: one real driver (retatrutide), one community recovery blend (KLOW), one weak-evidence add-on (injectable NAD+). The reta dose is sensible. But the author closes by asking what other peptides to add — and the honest editorial answer is none. The thing this stack is missing is a protein target and a resistance training program, both of which determine whether retatrutide-driven loss goes to fat or muscle.
@fastrlife reverse-aging starter pack — May 2026
The load-bearing 80% of this list is right: 8–9 hours of sleep, resistance training, sauna 3x/week, morning sun, social bonds, creatine, glycine. That's most of the actual longevity literature in one tweet. The other 20% is filler — seed-oil panic, 'micro-fasting dopamine,' a 6-drink-a-week alcohol allowance that openly contradicts the 'reverse aging' thesis — and the framing is the usual overclaim (these slow aging at best; nothing here reverses it). Still, a directionally sound starter pack.
@alexaaronlab 6-8 week rebound stack: KLOW + extra KPV + extra BPC-157 + Reta + MT2
A thoughtfully-disclosed rebound stack. Author uses KLOW as a baseline then adds extra KPV and BPC-157 on top, showing he understands the blend isn't titrated for any single compound. Reta at 2.5mg/wk is conservative for the recomp goal (Phase 2 dose range starts at 4mg). The active vs 'on hand' distinction (Ta-1, glutathione, NAD held in reserve) is more mature than most. Time-bounded 6-8 week framing tied to a specific 5-month-abroad rebound is the kind of goal-shaped protocol most stacks lack. Retatrutide sourcing applies.
@peptidepirate theoretical innate-immunity stack: Ta-1 + Ta-2 + LL-37 + Glutathione + NAD+
A 'theoretical' community-curated immunity stack with appropriately humble framing. The compounds are directionally right: Ta-1 has FDA orphan status and EU approval, LL-37 is the most-studied antimicrobial peptide, glutathione and NAD cover antioxidant bases. Three issues. 'Ta-2' is ambiguous; thymosin alpha-2 is real but obscure and may not be what the author meant. No doses are listed. And for actual hantavirus exposure, standard precautions (rodent-excrement avoidance, respirator when cleaning enclosed spaces) outperform any peptide protocol by orders of magnitude.
@biotides AM/PM peptide stack: Semax, GHK-Cu, Aminotadalafil, Selank, CJC/Ipa, BPC-157 — all listed at 5mcg
The doses don't pass sanity check. Every peptide in this stack is listed at '5 mcg,' which is roughly 50-100x below typical research-vendor protocols across the board. Telling: the only ingredient with a sane dose is Aminotadalafil at 5mg, the one small-molecule (non-peptide) compound. Either the author meant 5 mg uniformly (well above typical for Selank, Semax, and CJC/Ipa) or 5 mcg literal (sub-therapeutic for every peptide). The compounds and AM/PM split are otherwise reasonable, but the protocol as published isn't actionable.
@Subject-Light-1153's six-peptide "thoughts about these together?" grab bag
A grab bag with no doses and no goals. Six compounds — a triple incretin agonist, GH-axis stimulators, MOTS-C, two Russian nootropics, and NAD+ — all running blind without bloodwork or titration. The ingredients are individually defensible; the assembly is not. When something goes well or badly here, there is no way to attribute it to any one compound.
Brett Boettcher's 'High-ROI' 7-Supplement Stack
A defensible, modestly-framed supplement stack with the actual evidence base behind most of the picks. Creatine, magnesium glycinate, and D3+K2 are gold-standard 'high-ROI' commodity supplements; NAC, collagen peptides, and nattokinase have moderate evidence for the claimed uses. The 'plaque reversal' line on nattokinase is the only real overclaim — there's no human RCT showing fibrinolytic enzymes regress atherosclerosis. Otherwise an honest, low-cost stack worth roughly what the author says it is.
Peptide Peppers' GHK-Cu + TB-500 + Ipamorelin Skin/Hair Stack
A reasonable cosmetic peptide trio with sane doses, undermined by vendor-grade overclaims. GHK-Cu and ipamorelin have real mechanisms for skin and the GH pulse. TB-500's hair regrowth claim is animal-data only — there's no human trial showing it grows hair — and 'proved to have high efficiency' for the three-compound combo isn't backed by anything published.
Path of Men's Testosterone Cheat Sheet
A multivitamin wearing a testosterone t-shirt. Most of these compounds (zinc, magnesium, D3, selenium) only raise T in men who start deficient, and there's no bloodwork on the cheat sheet. Magnesium at 100 mg is well below the 200–400 mg used in any T-relevant trial, and the actual top-three levers for T — sleep, body fat, training — don't appear at all.
Michael Morelli's Epithalon + Pinealon sleep & brain peptide stack
The standard Khavinson playbook: two pineal-derived peptides, an appeal to '40+ years of Russian research' that isn't replicated outside one St Petersburg lab, no doses, and 'incredible' sleep results inside the textbook placebo window. Epithalon at least has a plausible melatonin-axis mechanism; Pinealon is along for the ride with even thinner data. Calling these 'overlooked' is generous — they're available everywhere with the marketing already written.
