- Has undergone Phase I clinical trials in humans, showing measurable increases in lean body mass in a dose-dependent manner.
- Well-documented binding affinity to androgen receptors (high potency).
- Known pharmacokinetics: Around 24–36 hour half-life, allowing for once-daily dosing in studies.
- Observed effects: Muscle gain with fewer side effects than anabolic steroids, but still with some testosterone suppression.
⚠️ LGD-3033:
- Has no public clinical trial data in humans.
- Most data is preclinical or speculative, possibly from animal models or patent filings.
- Claims of higher potency are anecdotal or based on non-peer-reviewed sources.
- Uncertain safety profile and no clear data on dosage, half-life, or side effects.
Bottom Line:
LGD-4033 is the only one with any human clinical data. So clinically, it’s the stronger and more reliable compound — not necessarily in potency alone, but in having known, tested effects and risks.
If you’re evaluating these compounds from a scientific or health standpoint, LGD-4033 has a clinical foundation. LGD-3033 is more of a black box.

Here’s a breakdown of what people on Reddit and similar forums say about LGD-4033 vs LGD-3033 — with the strong caveat that these are just anecdotal, unverified reports, not scientific evidence.
📬 What Reddit Users Say (Anecdotal Feedback)
LGD‑4033 (most‑discussed / “standard” SARM)
- Many users report notable strength and muscle gains. For example: “Gained twenty pounds, and CLEARLY lost fat … I was surprised … I went from benching just under 200 … to benching 265 for ten at the end of this ten weeks.” Reddit+2Reddit+2
- Some mention cleaner “bulk” results if dieting and training were on point. iSARMS.com+1
- On the downside — several users describe side effects such as hormonal suppression (“shut down natural T”), changes in lipids/cholesterol, “LGD‑flu” (flu‑like feel when starting), mood changes/insomnia, acne, and fatigue once the cycle ended. Reddit+2Reddit+2
- Others debate whether all gains come from the SARM — some argue that hard training + diet alone could explain large gains, or that SARMs’ effect is overhyped. Anabolic Minds+1
LGD‑3033 (much less common / more experimental)
- Fewer users share experiences — the data is far more sparse. Reddit+2Reddit+2
- Some claims say that LGD‑3033 produces “dry gains” (less water retention) with possibly good strength gains: “I got … 3303 and it was freaking strong as hell. No joke strongest compound I’ve ever taken.” Reddit+1
- Others warn about suppression and “dry” but “bubbly” appearance after cycles. Reddit+1
- However, there’s also frequent skepticism — some people say results were weak or negligible, or that batches might have been “bunk” (fake/ineffective). Reddit+2Reddit+2
Compared directly: What some Reddit threads conclude
- In a thread titled “LGD4033 vs LGD3033,” one user writes: “LGD4033 seems to be far more researched and used, where’s anecdotally LGD3033 has been compared to S23 and even RAD140 to some extent.” Reddit
- But in that same thread another comment says: “I got rats army 3303 … strongest compound I’ve ever taken.” (referring to LGD‑3033) Reddit
- So the experiences are highly inconsistent — some people swear by 3033, others say 4033 was more reliable.
⚠️ Why User‑Reported “Results” Are Unreliable — and Particularly for LGD‑3033
- Bias & variability: Gains may reflect differences in diet, training, sleep, other supplements — not necessarily the compound. Many posts themselves question whether gains came from “just training + eating big.” Anabolic Minds+1
- Unknown / questionable product quality: Some reports say their 3033 “batches” were “garbage.” Reddit+1
- Selection / survivorship bias: People who got good results (or had strong opinions) are more likely to post. Perhaps many who got nothing or had negative effects never return to post.
- Hormonal/health side‑effects: Several common complaints with 4033 include testosterone suppression, libido changes, insomnia, acne, cholesterol/lipid changes. Reddit+2Reddit+2
- Very limited reports for 3033: The sample size of self‑reports for 3033 is small. That alone makes generalization nearly impossible.
🎯 My Impression (Based on Reddit Trends + What We Know from Clinical & Preclinical Data)
- LGD‑4033 seems to have more consistent anecdotal “success stories” — more reports of increased strength/mass, though often with side effects.
- LGD‑3033 may produce “dry gains” for a few users, but the data is spotty and unreliable; some users say it’s “strong,” others got little to nothing or suspect the product was fake.
- Because of the variability, it’s impossible to conclude that LGD‑3033 is “objectively stronger” than LGD‑4033 based on Reddit — at best, some individuals claim stronger or different effects, but it’s not consistent enough to assume it generally is.
