Our Analysis
1-Andro vs 4-Andro: Our Real-World Take
We've tested thousands of these products across hundreds of cycles. 1-Andro and 4-Andro are not the same animal. One gets you drier and harder, the other gets you bigger, stronger, and actually feeling good. Pick wrong and you'll waste weeks wondering why you're not progressing.
Bottom line: 1-Andro for dry, lean, cosmetic results. 4-Andro for fullness, strength, libido, and that "on" feeling. For most people we steer toward 4-Andro because it simply delivers a better overall experience.
How They Stack Up
| Category | 1-Andro | 4-Andro |
|---|---|---|
| Full name | 1-Androstene-3b-ol,17-one | 4-Androstene-3b-ol,17-one |
| Converts to | 1-Testosterone | Testosterone |
| Primary goal | Lean mass, recomp, dry look | Size, strength, fullness, gym drive |
| Water retention | Low | Moderate to higher |
| Estrogen conversion | Does not aromatize | Converts downstream to estrogen |
| Typical feel | Hardening, drier, sometimes flat | More anabolic, fuller muscles, better mood/libido |
| Common daily dose | 100–300 mg/day | 100–300 mg/day |
| Beginner sweet spot | 150–200 mg/day | 150–200 mg/day |
| Advanced range | 200–300+ mg/day | 200–300+ mg/day |
What We've Seen in the Trenches
1-Andro is a precursor to 1-testosterone. It shines when you want to stay dry and tight. We see guys hold onto muscle during cuts, get that harder look, and recomp without bloating. It doesn't aromatize, so you avoid the soft, watery mess. The downside? A lot of users feel flat, libido tanks, and it can leave you looking sucked-out if run solo. It's a physique tool, not a feel-good compound.
4-Andro converts to straight testosterone. This is the one that actually makes training fun again. Better aggression in the gym, nasty pumps, real strength jumps, fuller muscles, and solid mood and libido support. Yeah, it can bring some water and estrogenic effects, but that's often exactly why it feels better than 1-Andro. Most guys prefer how they look and feel on it.
Dosing (The Part That Actually Matters)
Dose separates the real products from the garbage.
For 1-Andro:
- 100 mg/day is weak sauce
- 150–200 mg/day is where beginners should start
- 200–300 mg/day is the effective range we see results with
- 300+ is advanced
Anything under 150 mg daily is usually underdosed trash.
Same story with 4-Andro:
- 150–200 mg/day minimum for most people
- 200–300 mg/day for serious results
We've seen too many bottles with 50-75 mg per serving. Those get returned.
Capsules vs Transdermals
Capsules win on convenience. Transdermals win on effectiveness. We've run both extensively — a good transdermal at 200 mg feels noticeably stronger than the same dose in a capsule. If the product's worth a damn, the transdermal version usually justifies the extra cost.
Price Reality Check
Both are mid-to-premium. Stop buying the cheapest bottle. A "bargain" 1-Andro or 4-Andro with only 60 caps at 75 mg each is actually expensive once you run proper doses. Calculate total milligrams and days at effective dosing. We watch guys learn this lesson the hard way every month.
Who Should Use What
Buy 1-Andro if:
- You're cutting or recomping
- You want that dry, hard look
- You're stacking it with 4-Andro or something wetter
- Mirror results matter more than scale weight
Buy 4-Andro if:
- You're bulking or chasing strength
- You want better pumps, drive, and mood
- You're a first-time user
- You want something that just *feels* right
For cutting: 1-Andro wins.
For bulking: 4-Andro wins.
For recomp: 1-Andro gets the slight edge if staying tight is priority one.
First cycle: 4-Andro. Hands down. 1-Andro solo can be disappointing.
Our Final Call
4-Andro wins for most people.
After testing both for years, 4-Andro delivers the more complete package — better workouts, better strength, better fullness, better mood, and results people can actually feel and see. It's more versatile and less likely to leave you disappointed.
That said, if your main goal is a dry, granite-hard look with zero bloat, 1-Andro is the superior tool. Use it for cuts and recomp phases.
Simple rule we give every customer:
Want to feel like a beast and make fast progress? Grab 4-Andro.
Want to look carved and dry? Grab 1-Andro.
Don't overthink it. Pick based on your actual goal, dose it properly, and run it right.
