All QSC Steroids Compounds — Available in United States
All compounds below are in stock in the USA (domestic) warehouse and available for research orders in United States.
The A:A ratio compares anabolic activity (levator ani assay) to androgenic activity (prostate assay) vs testosterone (100:100 baseline). Key QSC Peptides ratios: Anavar 322:24, Trenbolone 500:500, Nandrolone 125:37, Dianabol 210:60, Winstrol 320:30, Anadrol 320:45, MENT 650:250.
Testosterone Enanthate is testosterone with a heptanoate (C7) ester providing ~7-day half-life. The most widely used injectable testosterone ester in research. QSC Peptides offers 250mg/mL in 10-vial kits.
Nandrolone Decanoate is 19-nortestosterone with a C10 decanoate ester (~15-day half-life). 125:37 anabolic:androgenic ratio — 25% more anabolic than testosterone with 63% less androgenicity. 5α-reduces to inactive DHN rather than DHT.
Trenbolone's Δ9,11 double bonds increase AR binding affinity ~3–5× testosterone, prevent aromatization, and prevent 5α-reduction — producing uniform 5× potency on both anabolic and androgenic axes. Strong progestin receptor agonist (~60% progesterone affinity).
Dianabol is 17α-methyl-Δ1-testosterone — the original oral AAS. C17α methylation enables oral bioavailability. 210:60 ratio. Aromatizes to 17α-methylestradiol (potent ER agonist). QSC Peptides offers 10/20/50mg tablets and injectable oil form.
Anavar is oxandrolone — a DHT derivative with 2-oxa A-ring modification giving 322:24 anabolic:androgenic ratio. No aromatization. Predominantly renal excretion (lower hepatotoxicity vs other oral AAS). QSC Peptides offers 50mg tablets.
MENT is 7α-methyl-19-nortestosterone acetate — the most anabolically potent injectable AAS at ~650:250 ratio. Does not 5α-reduce to inactive metabolite. Aromatizes to 7α-methylestradiol. QSC Peptides offers 50mg/mL in 10-vial kits.
DHT derivatives (Anavar, Winstrol, Masteron) are derived from 5α-dihydrotestosterone. They cannot aromatize and cannot 5α-reduce further. Each has a unique A-ring modification: Anavar (2-oxa), Winstrol (pyrazole), Masteron (2α-methyl with AI activity).
19-nor steroids (Nandrolone, Trenbolone, MENT) lack the C-19 methyl group of testosterone. This prevents full aromatization in most cases and produces different 5α-reduction products — DHN (inactive, low androgenicity) for nandrolone, no reduction for trenbolone.
Masteron (Drostanolone) is a 2α-methyl DHT derivative that directly inhibits CYP19A1 (aromatase), reducing estrogen biosynthesis while simultaneously activating AR. It's the only AAS that functions as a steroidal AI.
Equipoise is boldenone undecylenate — the Δ1 analog of testosterone with a C11 undecylenate ester (~14-day half-life, the longest of any common injectable AAS). 100:50 ratio, ~50% aromatization rate vs testosterone, associated with EPO stimulation.
QSC Peptides offers: Clomiphene Citrate (Clomid) 50mg, Tamoxifen Citrate (Nolvadex) 20mg, Exemestane (Aromasin) 25mg, Anastrozole (Arimidex) 1mg — for HPTA restoration research following AAS models.
