Rentox 200U is the same PharmaResearch Bio preparation as the 100-unit vial, in the size clinics reach for when the list is full. Two hundred units covers several full-face sessions, or the larger-muscle work — masseters, calves, trapezius — where unit counts climb quickly.
The arithmetic is the same as it is for any toxin. Each vial carries the same fixed costs of manufacture, packaging and cold-chain freight, so the larger vial always lands at a lower price per unit. For a practice treating steadily that difference compounds across a year; for one treating occasionally it does not, because an opened vial has a limited working life and product poured away costs more than the saving.
What distinguishes Rentox from most of the Korean field is the formulation rather than the vial: it is made without albumin or gelatin.
Why practitioners choose the 200-unit vial
Lower cost per unit
The clearest reason. Where throughput justifies it, the 200U vial is the most economical way to buy Rentox.
Albumin-free formulation
No human serum albumin and no animal-derived gelatin. For clinics fielding questions about what is in the vial, this is the reason Rentox gets specified over conventional albumin-stabilised products.
Suited to high-unit treatments
Masseter reduction, calf slimming and trapezius work consume units fast. A 200-unit vial covers bilateral treatment without opening a second box mid-session.
Identical to the smaller vial otherwise
Same manufacturer, same formulation, only the fill differs. A clinic standardised on Rentox can move between sizes without changing anything else about its protocol.
What it is used for
Glabellar lines, horizontal forehead lines and crow's feet account for the bulk of aesthetic use. Beyond that: masseter reduction and jawline slimming, perioral lines, platysmal bands, and calf or shoulder contouring where large muscle groups are involved. Hyperhidrosis of the underarms and palms is a common non-wrinkle application.
Therapeutic uses include blepharospasm and limb spasticity. Approved indications vary by market, and treatment should stay within your own scope of practice.
Composition
Clostridium botulinum toxin type A, 200 units per vial, formulated without albumin or gelatin. It works by blocking acetylcholine release at the neuromuscular junction, producing temporary and reversible relaxation of the treated muscle. Supplied as a lyophilised white powder that reconstitutes to a clear, colourless solution.

Handling
Inspect the vial before use — the cake should be white to slightly off-white and the seal intact. Reconstitute with sterile 0.9% sodium chloride, adding the diluent gently rather than shaking. Follow the diluent volumes and per-site dosing in PharmaResearch Bio's prescribing information.
Reconstituted solution should be used promptly and refrigerated in the interim. Effect duration is typically three to six months, varying with dose, treated area, muscle bulk and how quickly the individual metabolises it.
A prescription product for trained, licensed practitioners only. Contraindicated in pregnancy and breastfeeding, in known hypersensitivity to any component, where infection is present at the injection site, and in neuromuscular disorders such as myasthenia gravis.
