Proviron (mesterolone) is described variously as an aromatase inhibitor, a libido drug and a hardening agent. It is none of those exactly. Its main action is binding sex hormone binding globulin, which frees up testosterone you already have. Understanding that explains everything else people report about it. The actual mechanism Most testosterone in your blood […]

Three aromatase inhibitors are commonly used: anastrozole (Arimidex), exemestane (Aromasin) and letrozole (Femara). They differ in potency and in one structural respect that matters — exemestane binds irreversibly, the other two do not. Letrozole is the strongest and is usually the wrong choice. What an aromatase inhibitor does Aromatase is the enzyme that converts testosterone […]

Clomiphene (Clomid) and tamoxifen (Nolvadex) do the same job by the same mechanism — both block oestrogen feedback at the hypothalamus so LH and FSH rise and testosterone production restarts. The meaningful difference is side effects, and for most people that difference points to tamoxifen. Why they are more alike than different Both are SERMs. […]

hCG mimics luteinising hormone and stimulates the testes directly. That is the one thing SERMs like tamoxifen and clomiphene cannot do — they work on the brain and rely on the testes still responding. If suppression has been long, that assumption fails, and hCG is what addresses it. Why it is different from a SERM […]

Androgen-driven acne does not respond well to ordinary treatments because the cause is hormonal rather than bacterial. Isotretinoin (Accutane) works where they fail — it shrinks sebaceous glands directly. It is also the most side-effect-heavy drug most people here will encounter, and it overlaps badly with oral steroids on the liver. Why anabolics cause acne […]

Tamoxifen — sold as Nolvadex — is a selective oestrogen receptor modulator (SERM). It does not lower oestrogen. It blocks oestrogen from acting at specific receptors while leaving it active at others. That distinction is the whole reason it works for post-cycle recovery and is a poor choice for on-cycle oestrogen control. Blocking is not […]

These are the two deepest ranges we stock — Ultima Pharmaceuticals at 135 lines, Euro Pharmacies at 127 — and on paper they look interchangeable. They are not. Ultima is weighted towards peptides and growth hormone; Euro Pharmacies towards conventional injectable anabolics. Which one suits you depends entirely on what you are actually buying. Side […]

Four brands sit in the middle of our catalogue by depth — Mactropin (62 lines), Genetic Labs (54), Spectrum Pharmaceuticals (44) and La Pharma (42). That is enough to build a cycle from a single manufacturer but not enough to cover every ancillary, and knowing where each runs out saves an order. The four Brand […]

Five brands in our catalogue sell food supplements, not medicines — Magnus, Hi-Tech Pharmaceuticals, Elbrus, Brawn Nutrition and Zion Labs. They sit under entirely different legislation from everything else here, which changes what is legal, what is verified, and what will show up on a drug test. The five Brand Lines Price Known for Magnus […]

Four brands we stock are peptide specialists rather than general manufacturers — Bio-Peptide, Bioamino Labs, Canada Peptides and ZPHC. Their pricing diverges wildly: Bio-Peptide starts at £25, Canada Peptides at £110. That gap is not a quality ranking, and this page explains what actually drives it. The four Brand Lines Price range Weighted towards ZPHC […]
