Mentabolan + Pemetrexed
Pemetrexed brand names: Alimta, Pemfexy.
We found no known interaction between Mentabolan and Pemetrexed in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
Mentabolan and Pemetrexed
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Pemetrexed and Mentabolan in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Mentabolan at all — not against Pemetrexed, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

From our pharmacist’s overview on the Pemetrexed page
“Every supplement on file for pemetrexed (Alimta, Pemfexy) works the same way. Each can slow how the kidneys pull the drug out of the blood, which would let it linger and build to higher levels than intended.”

About Mentabolan
What is Mentabolan?
- Muscle building and strength
- Athletic performance enhancement
- Body recomposition
- Sold as a 'prohormone' bodybuilding supplement
Mentabolan is a marketing name for a synthetic steroid-like compound (often linked to dimethandrostenediol/prohormone chemicals) sold in some bodybuilding 'prohormone' products, not a natural herb. These designer steroid products can be unsafe, may be illegal or unapproved, and have been associated with liver and hormonal harm, so we strongly recommend avoiding them and talking with a doctor or pharmacist.
Not applicable (synthetic compound) · Capsules, tablets
