Body Pharm Retatrutide vs UK SARMs Retatrutide: Pen Review

Two pre-filled UK research retatrutide pens that both publish a Certificate of Analysis. This one comes down to price per mg and the breadth of testing. Body Pharm's 64 mg pen is cheaper per mg; UK SARMs lists a marginally higher headline purity figure. Here is the factual side-by-side — UK SARMs figures are from their own listing (captured 5 July 2026); verify current details before ordering.

The differences that matter

Cheaper per mg

Body Pharm's 64 mg pen works out at £5.00/mg against the UK SARMs 40 mg pen at £6.25/mg — around 20% less for the same peptide, in the same pre-filled pen format.

Both publish a COA — Body Pharm's goes further

UK SARMs publishes an HPLC purity report (99.55%, MZ Biolabs). Body Pharm's per-batch Certificate of Analysis reports HPLC purity (98.75–99.3%) plus sterility, bacterial endotoxins, pH and phenol content — a fuller release specification.

Pre-filled pen, UK dispatch

Both ship pre-filled pens (no reconstitution) tracked from the UK. On raw purity UK SARMs edges it by under 1%; on price per mg and testing breadth, Body Pharm leads.

Verdict

The closest match in the comparison set: both are pre-filled retatrutide pens that publish HPLC purity data. UK SARMs lists a marginally higher purity figure (99.55% vs Body Pharm's 98.75–99.3%). Body Pharm counters with a lower price per mg (£5.00/mg vs £6.25/mg on the headline pens) and a broader release specification — its COA adds sterility, endotoxin, pH and phenol testing. For the best documented value in a pen, Body Pharm has the edge; UK SARMs is the pick if a fractionally higher stated purity outweighs the higher per-mg cost.
