Covering the full spectrum from tissue selective anabolic SARMs for muscle and bone research, to PPARδ agonists for endurance and metabolic research, to growth hormone secretagogues that are frequently categorized alongside SARMs due to their overlapping research applications. Every compound is independently HPLC tested before listing with certificates of analysis available on request.
What are SARMs and how do they differ from anabolic steroids?
Selective Androgen Receptor Modulators (SARMs) are a class of androgen receptor ligands that bind and activate androgen receptors with tissue selectivity. Producing anabolic effects in muscle and bone tissue while minimizing androgenic activity in other tissues such as the prostate, skin, and hair follicles. This selectivity is achieved through differential receptor conformation changes induced by the SARM compared to testosterone. Recruiting different coactivator proteins in different tissue types. The theoretical advantage over traditional anabolic steroids is meaningful anabolic activity with a reduced side effect burden, specifically reduced androgenic side effects, reduced hepatotoxicity (SARMs are not 17-alpha alkylated), and reduced cardiovascular impact compared to oral anabolic steroids. In practice, the degree of selectivity varies significantly between SARMs with some compounds demonstrating near complete tissue selectivity and others showing meaningful suppression and androgenic activity.
The most researched SARMs | Ostarine, RAD-140 and LGD-4033
Ostarine (MK-2866) is the most extensively clinically researched SARM, having completed multiple Phase II clinical trials for muscle wasting and osteoporosis. It demonstrates meaningful anabolic activity in muscle and bone at low doses (10–25mg per day) with minimal suppression at short cycle lengths. Making it the most studied entry level SARM for lean mass preservation research. RAD-140 (Testolone) is a potent non steroidal SARM with an anabolic to androgenic ratio reported at 90:1 compared to testosterone. Producing strong anabolic effects in muscle tissue with high selectivity. LGD-4033 (Ligandrol) is a high affinity, orally bioavailable SARM that completed Phase I clinical trials, demonstrating dose dependent lean mass increases with dose dependent HPG axis suppression. Making it one of the most potent and most researched SARMs in the catalogue.
Cardarine, MK-677 and associated research compounds
Cardarine (GW501516) is frequently categorised with SARMs despite not being an androgen receptor modulator; it is a PPARδ agonist studied for its profound endurance enhancing and lipid improving effects. It increases fatty acid oxidation, dramatically improves aerobic capacity, raises HDL, and reduces LDL and triglycerides in research models. MK-677 (Ibutamoren) is an oral ghrelin receptor agonist that stimulates GH and IGF-1 secretion. Categorized with SARMs due to overlapping research applications in body composition optimization. SR9009 (Stenabolic) is a REV-ERBα agonist studied for its effects on circadian rhythm, metabolism, and endurance. All three are stocked by CSD alongside the core SARM compounds.
SARMs suppression, PCT and safety considerations
All androgenic SARMs produce dose dependent HPG axis suppression reducing LH, FSH, and endogenous testosterone production. The degree of suppression varies by compound, dose, and cycle length. Ostarine at low doses for short cycles produces minimal suppression. RAD-140 and LGD-4033 at standard research doses produce meaningful suppression requiring post cycle recovery. S23 produces near complete suppression comparable to traditional anabolic steroids. Post cycle therapy with SERMs (Nolvadex, Clomid) is researched for HPG axis recovery following suppressive SARM cycles. The same compounds used in anabolic steroid PCT. Cardarine carries a carcinogenicity warning from long term rodent studies researchers should review the full safety literature before use.

SARMs are not approved by Health Canada for human use and are not scheduled as controlled substances under the Controlled Drugs and Substances Act. They exist in a regulatory grey area, not illegal to possess but not approved for sale as therapeutic products. All SARMs on Canada Steroid Depot are sold for research purposes only. Regulations may evolve, review applicable regulations in your jurisdiction before ordering.
Yes! Androgenic SARMs produce dose dependent HPG axis suppression. Mild compounds such as Ostarine at low doses for short cycles may require only a brief recovery period with minimal SERM intervention. More suppressive compounds such as RAD-140, LGD-4033, and particularly S23 require a full SERM based PCT protocol comparable to anabolic steroid recovery. Blood work before, during, and after SARM cycles is strongly recommended to monitor suppression and guide PCT decisions.
Ostarine is the mildest and most clinically researched SARM; ideal for lean mass preservation, recomposition, and injury recovery research with minimal suppression at appropriate doses. RAD-140 is more potent with a very high anabolic to androgenic selectivity ratio. Producing stronger anabolic effects with meaningful suppression at research doses. LGD-4033 is the most potent of the three in terms of lean mass gains in clinical research, with the most significant suppression, producing the strongest anabolic effects but requiring the most robust PCT protocol.
Yes! SARMs are commonly researched in combination protocols stacking compounds with complementary mechanisms. Common research stacks include Ostarine + Cardarine for recomposition research, RAD-140 + MK-677 for lean mass and recovery, and LGD-4033 + MK-677 for maximized anabolic and GH secretagogue effects. Stacking multiple androgenic SARMs compounds suppression. PCT planning should account for the cumulative suppressive effect of the stack rather than individual compounds.
