SecretagoguesIbutamoren (MK-677): the oral secretagogue with a two-year human trial
Most compounds in this catalog have no human data at all. This one has three randomised trials: a pulse study from 1996, an obesity study from 1998, and a two-year trial in 65 older adults that added fat-free mass without moving visceral fat. The numbers, exactly as published.

MetabolicLiver support pens: reading the label against the literature
Two multi-ingredient liver pens, opened up component by component. Silymarin has a Cochrane review that reads against it, NAC has a poisoning antidote trial that does not transfer, and the finished blends have no trial at all.

RepairBPC-157 in tendon research: what the rat studies actually show
Tendon models are the core of the BPC-157 animal literature, and a 2025 systematic review put the field's ratio at 35 preclinical studies to 1 clinical study. This page stays inside that ratio.

HormonalHCG and enclomiphene: what the fertility trials actually studied
Two compounds, four published studies, and a hard boundary: the literature describes what was measured in enrolled patients — intratesticular testosterone, sperm counts, pregnancies — not a protocol for anyone else. This article stays on the published side of that line.

GH axisHGH vs peptides: somatropin and the secretagogues, compared on the evidence
One is the hormone itself, approved since the 1980s for defined deficiency states. The others ask the pituitary to release more of it — and have one small trial, one PK study, or a single approval between them. The comparison searchers want has never actually been run.

HormonalMelanotan 2: three small trials, no approval — and the relative that got one
The entire human literature on Melanotan 2 is three trials in 23 men, run by one Arizona group in the 1990s. Nothing followed for tanning. Its chemical relative bremelanotide became an approved medicine — for one narrow indication that has nothing to do with tanning.

BlendsOxytocin: the approved hormone inside the OxyPT blend
One half of the OxyPT blend is among the oldest approved peptide drugs in medicine — used in obstetrics since the 1960s. Here is what the labels actually cover, and what they pointedly do not.
28 września 2026 · 1 min czytaniaSARMsSARMs part 2: the one with trials, and the four with none
Part 1 covered the compounds with phase 2 and phase 3 programmes. The five left — ibutamoren, stenabolic, andarine, S-23, YK-11 — split into one with three real human trials and an ugly safety footnote, and four with no human efficacy data at all. Two of the five are not even SARMs.

BioregulatorsCartalax and Chonluten: the bioregulators with almost no published record
Same Khavinson school as Thymalin and Epithalon, a fraction of the evidence. One cell-culture study for Chonluten, no readable efficacy study at all for Cartalax — and that asymmetry is the article.

LongevityEpithalon and the telomere claim: what the Khavinson papers actually report
Telomerase reactivation in a dish, extra passages past the Hayflick limit, longer-lived flies and mice — and no modern human trial. The published Epithalon record, figure by figure.

PerformanceMyostatin inhibitors: ACE-083 went to phase 2, follistatin-344 never left the lab
One follistatin-based molecule grew muscle in two randomised phase 2 trials and still failed where it mattered. The other has only animal data, a black market, and a retinal case series. The published record, side by side.

RepairARA-290 (cibinetide): four human trials, and the endpoints they missed
This is one of the very few compounds on the repair shelf with real randomised human data — four published trials, including a 64-subject phase 2b. Read them closely and the nerve-regeneration endpoint separates from placebo while the pain endpoint mostly does not.

PerformanceExercise mimetics: what AICAR, SLU-PP-332 and 5-Amino-1MQ have actually done, and in what species
One of these three has been given to 3,080 humans — and the trial was stopped for futility. The other two have never been given to a human at all. All three are sold on the same phrase, and the phrase comes from one mouse treadmill experiment in 2008.

MetabolicTesofensine: a phase 2 result that never became a phase 3 paper
The 2008 Lancet trial is real, and the numbers in it are large. What followed is the part nobody quotes — an Expression of Concern from the journal, no published phase 3 anywhere in the indexed literature, and no approval in the EU or the US.

LongevityEndurance, GlutaMB and the antioxidant pens: the labels add up, the trials are less flattering
Glutathione, NMN, resveratrol and methylene blue, in two pre-mixed pens. One component has a good human trial, one has four negative ones, and one is present at a dose thousands of times below the trial that reported a benefit. Ingredient by ingredient.

ProgramsThe four programs: what you are actually buying when you buy one
A program is the manufacturer's own multi-month protocol sold as the set of pens it calls for — priced below the sum of its parts, delivered on one fee. Here is what is in each of the four, and how strong the evidence under each component really is.

SleepDSIP: named after an effect that later human work could not reproduce
Isolated from rabbit blood in 1977 and named for the EEG rhythm it enhanced. Four small human insomnia studies produced weak or null results, a 2009 anaesthesia study found it reduced delta rhythm, and no gene or receptor has ever been identified.

MetabolicHGH Fragment 176-191 and AOD9604: a well-built mouse story with a missing human chapter
The idea was elegant — take growth hormone's fat-metabolism domain and leave the growth and insulin effects behind. It worked in obese mice, repeatedly. PubMed indexes 23 papers mentioning AOD9604 and not one randomised human trial.

GH axisIGF-1 LR3 and PEG MGF: two names, and what is actually published under each
Recombinant IGF-1 is an approved drug with a registry behind it. The LR3 analogue is a cell-culture reagent. PEG MGF has no administration study at all — the human MGF papers measure a gene switching on, not a peptide going in.

RepairKPV: three amino acids off the end of α-MSH, and where its evidence actually sits
The mechanism is unusually well worked out — KPV enters cells through PepT1, a transporter that is upregulated exactly where gut inflammation is. Every efficacy result is a mouse or a cell line, and the colitis work was oral, not injected.
