Xeno Laboratories

Injectable Range and Ester Selection

The Xeno injectable range is built around esters, which means the same parent compound appears in more than one form. Testosterone is listed as Propionate 100, Enanthate 250 and Cypionate 200, all supplied in 10 ml vials. The propionate ester clears in a few days and is normally pinned more frequently, while the enanthate and cypionate esters hold steadier levels and suit a once or twice weekly schedule. Nandrolone follows the same pattern with Decanoate 200 for slower release and NPP 100 for a shorter, faster-clearing option.

Trenbolone is available as Acetate 100, Enanthate 200 and Parabolan 76, which gives users a short, a long and an intermediate ester from the same label. Drostanolone appears as Masteron 100 and Masteron Depot 200, and methenolone enanthate as Primobolan 100. Boldenone Undecylenate 300 and DHB 200 extend the range into vascularity and endurance work, while Trestolone MENT 50 covers an advanced dry-mass option. Ester length is the single most important detail to check before a stack is built, and the testosterone, trenbolone and Deca and NPP pages explain the differences in more depth.

Xeno also produces several concentrated blends such as MegaTest 500, SuperTest 375, OmniMass 500 and Omnicut 300. A blend reduces the number of injections, but it also fixes the ratio between esters, so it cannot be fine-tuned the way separate vials can.

Oral Tablets and Dose Ladders

The oral range runs from the mild to the strong end of the scale. Anavar 20 and Primo S 10 are the gentler tablets and are usually associated with cutting and definition work, while Dbol 20 and Anadrol 25 sit at the mass end and are known for rapid strength and weight gain. Between them, Winstrol 20 and Turinabol 10 cover strength phases, and Halotestin 10 covers short pre-contest blocks where hardness is the priority. Metribolone 1 is the most potent tablet in the line and is dosed in single milligrams.

Ancillary orals complete the picture: Clomiphene 50 and Tamox 20 for recovery, Arimidex 1, Aromasin 25 and Femara 2.5 for estrogen control, Proviron 25 as a mild androgen support, plus Finasteride 1 and Avodart 1 for hair-related concerns and Accutan 20 for skin. Clenbuterol 40 mcg, T3 25 mcg and T4 100 mcg belong to thermogenic and metabolic protocols. Tablet packs are usually 30, 50 or 100 units, so the pack size is worth checking whenever a dose ladder is planned.

Recovery Support and Ancillaries

Recovery is planned before the cycle starts, not after it ends. Clomiphene 50 and Tamox 20 are the two SERM choices in the Xeno line, used together or separately depending on how suppressive the cycle was. Aromatase inhibitors are split by strength as well: Arimidex 1 is the mid-range option, Aromasin 25 is a steroidal inhibitor that users often prefer for a smoother taper, and Femara 2.5 is the strongest of the three and is reserved for when the estrogen load is difficult to control.

For users who want to maintain testicular function during a heavy cycle, Xeno supplies HCG 5000 IU and HMG 75 IU. Cabergoline is covered as a prolactin-focused ancillary in the same support section, and the post-cycle therapy page explains how these products are sequenced after the last injection. The on-cycle page covers what belongs in the middle of a run rather than at its end.

Peptides in the Xeno Line

Xeno keeps a compact peptide group that mirrors its main research interests. BPC-157 5 mg is a pentadecapeptide studied in animal models for tissue repair and gut protection. Epitalon 5 mg is the AEDG tetrapeptide, Selank 5 mg is a synthetic heptapeptide and tuftsin analog, and Semax 5 mg is a heptapeptide studied as an ACTH(4-10) analog. All four are lyophilized and are documented on the peptides hub and the recovery peptides page.

The metabolic side of the peptide group is represented by Semaglutide 10 mg, a GLP-1 receptor agonist, and Tirzepatide 10 mg, a dual GIP and GLP-1 agonist. Both arrive as lyophilized powder, are reconstituted with bacteriostatic water and stored cold, and their research context is described on the fat loss page. None of these compounds is an approved medicine, and human pharmacokinetic data are limited for most of them, which is why they are presented here as research materials.
