If you've walked into your favorite supplement shop or browsed online recently looking for Hi-Tech Pharmaceuticals’ prohormones like 1-Testosterone, Androdiol, or Superdrol, you might’ve noticed something odd—they’re missing. Even Blackstone Labs Chosen1, once a staple in many bulking cycles, has quietly disappeared from shelves. So what exactly is going on? And more importantly, what are your options while these heavy hitters are off the market?
Let’s break down the current state of prohormones, the behind-the-scenes drama with the FDA, and the best alternatives to run until (or if) these products return.
The Legal Tug-of-War: FDA vs. Hi-Tech Pharmaceuticals
Details are still murky, but the crux of the issue seems to revolve around 1-Andro and 4-Andro, the core ingredients in many of the industry’s most popular prohormones. The FDA and Hi-Tech Pharmaceuticals have a long and well-documented history of legal skirmishes, and this latest battle appears to focus specifically on these compounds.
What's unclear is whether the FDA’s crackdown is aimed at the actual chemical structures of 1-Andro and 4-Andro, or if it's more about the product names and branding—we’ve heard reports pointing in both directions. Initially, it seemed Hi-Tech planned to re-release the same compounds under new names, but those plans appear to be stalled.
Here are some of the major casualties of this recent purge:
-
Hi-Tech 1-Testosterone
-
Hi-Tech 1-AD
-
Hi-Tech Androdiol
-
Hi-Tech Superdrol
-
Blackstone Labs Chosen1 (1-Andro based)
These products have been off the market for a few months now, with no official word on when—or even if—they’ll return.
LG Sciences: The Last Brand Standing?
Surprisingly, LG Sciences 1-Andro is still available through some retailers. It’s unclear whether LG Sciences has avoided the FDA’s radar due to its lower popularity, different formulation, or simply luck. It’s worth noting that LG’s version is significantly lower dosed than Hi-Tech’s or Blackstone’s offerings, which may be why it hasn’t triggered the same level of scrutiny.
That said, availability is spotty, and in some cases, stores have to break open their “kits” to sell the 1-Andro as a standalone item. If you can find it, it’s the closest direct substitute to the more potent 1-Andro products—but be aware that you may need to adjust your dosing or expectations accordingly.
Best Alternatives While You Wait
For 1-Testosterone / 1-AD / Chosen1
If you’re trying to replicate a 1-Andro-based cycle, your options are limited. However, these are your best bets:
-
LG Sciences 1-Andro
As mentioned, it’s lower dosed, but it's still 1-Andro and technically still available. Great if you want to maintain consistency with past cycles, but may require stacking or extending the duration for comparable results. -
Hi-Tech Halodrol
This is arguably the best replacement for 1-Testosterone right now. It combines 1-Andro and 4-Andro, leaning toward a lean bulking profile. If you’re looking for something potent and still available, Halodrol is your go-to. -
Hi-Tech Primobolan
This one’s a blend of 1-Andro and Epiandro, making it a sort of hybrid between 1-Testosterone and Winstrol. It’s lower dosed and milder overall, but makes for a solid cutting stack or a lean recomp if you’re not chasing extreme gains.
For Androdiol (4-Andro)
If you’ve been a fan of Hi-Tech Androdiol, which features 4-Andro, here are the best alternatives:
-
Blackstone Labs Brutal 4CE
A strong replacement for Androdiol, Brutal 4CE is a straight 4-Andro product that uses multiple esters for time-released delivery. It’s arguably a better designed 4-Andro than Androdiol in some ways, and perfect for size and strength. -
Hi-Tech Andriol
Still available and a more “long-term safe” prohormone option for those looking to run cycles for extended periods. It doesn’t hit quite as hard as Brutal 4CE but offers a good balance of results and sustainability.
For Superdrol
If you’re missing the dry, hard-hitting gains from Superdrol, here are two solid replacements:
-
Innovative Labs Monster Plexx
A multi-compound prohormone designed to deliver serious results. It’s a great choice for experienced users looking for a Superdrol-type effect. -
Hi-Tech Halodrol
Yes, Halodrol makes this list twice—and for good reason. It’s one of the most versatile prohormones still available, and depending on your cycle goals, it can even mimic Superdrol’s lean gains if dosed appropriately.
Final Thoughts
While the future of 1-Andro and 4-Andro prohormones remains uncertain, it’s clear the market is in a temporary state of limbo. Between regulatory pressure, product reformulations, and legal battles, there’s no telling exactly when—or if—Hi-Tech’s original lineup will return. In the meantime, you’ve still got options, but you’ll need to be a bit more strategic about your stack, dosage, and goals.
Stay tuned for more updates as this situation evolves. We’ll be watching closely and keeping you posted as soon as anything changes.
