Description
The RAD-140 and LGD-4033 stack puts two of the strongest SARMs in one order. It’s aimed at labs comparing high-affinity androgen receptor ligands.
Buy the RAD-140 and LGD-4033 stack online
You get two full bottles: liquid testolone and liquid ligandrol. Buying them as a stack costs less than ordering each bottle on its own, and everything ships together in one package. Each bottle is filled from a batch with its own certificate of analysis, and each one has its own pipette, so there’s no cross-contamination between compounds.

What’s in the RAD-140 and LGD-4033 stack?
RAD-140 (testolone) is a high-affinity SARM from Radius Health with a long reported half-life and a strong anabolic profile in animal models. LGD-4033 (ligandrol) binds the androgen receptor at around 1 nM, one of the highest affinities of any SARM, and has phase I and II human data.
Both compounds bind the androgen receptor tightly and are selective for muscle and bone. LGD-4033 has more human data. RAD-140 has a longer reported half-life.
Research behind the RAD-140 and LGD-4033 stack
Because both act on the same receptor, effects like testosterone suppression and HDL changes may stack up. LGD-4033’s phase I trial reported both at higher doses, and RAD-140 studies report suppression too.
Plan controls for each compound alone. The ligandrol trials are on PubMed.

Measuring and storage
Each compound comes in its own glass bottle with a graduated 1 mL glass pipette, so you can measure each one separately and keep your records clean. Label your draws by bottle, because the solutions look alike.
Store all the bottles upright, tightly capped and away from heat and direct sunlight. Room temperature is fine for PEG-400 solutions.
Lab testing and certificate of analysis
Each bottle in the RAD-140 and LGD-4033 stack comes from a batch tested by MZ Biolabs, an independent lab in Arizona. RAD-140: COA 10/17/2025. LGD-4033: 99.74% (COA 10/26/25). Ask us for the full certificates and we’ll email them over.
RAD-140 and LGD-4033 stack FAQ
Why combine two strong SARMs?
Mainly for comparison work, so both can be measured under the same conditions.
Will suppression be stronger?
Probably, since both act on the androgen receptor.
What concentrations are included?
RAD-140 at 15 mg/mL and LGD-4033 at 10 mg/mL.
Why researchers buy from Sports Technology Labs
Research only works when the material matches the label. That’s why an independent lab (MZ Biolabs) checks every batch we sell, and it’s why we print the COA date and purity on each page. We bottle in the USA and pack liquids in UV-resistant glass with tamper-evident seals. If a COA ever doesn’t match, we don’t sell the batch.
