TrainedByJP Natural Physique - Beta-Ecdysterone for Muscle Mass

What is TrainedByJP Natural Physique?

It is a single-ingredient supplement in vegetarian capsules, dosed at 255 mg of beta-ecdysterone per capsule. The daily serving is two capsules, i.e. 510 mg, and the 60-capsule bottle covers 30 days.

Beta-ecdysterone, or 20-hydroxyecdysone, is a phytosteroid: a molecule found naturally in certain edible plants, including spinach and quinoa, as well as in insects. The “steroid” prefix causes confusion and deserves to be defused: it is neither a hormone nor a testosterone derivative, and its structure belongs to a distinct plant family.

The formula is complete simplicity: the active, microcrystalline cellulose as a bulking agent, a hypromellose capsule and magnesium stearate. No flavouring, no blend, no “proprietary complex”. Because the capsule is plant-based, the formula is suitable for vegetarians and vegans. The full range is in our TrainedByJP aisle.

What does a daily serving contain?

Other ingredients: microcrystalline cellulose, vegetarian capsule (hypromellose), magnesium stearate. Pack size: 60 capsules, i.e. 30 daily servings. No energy value is declared, and at this scale it is negligible.

So much for the facts. Let us turn to what matters most on this product, and we are going to be very direct: no health claim is authorised in Europe for ecdysterone. None. So you will not read on this page any promise of muscle mass, of strength, of protein synthesis or of recovery.

Nor will we go any further into the mechanisms. Marketing copy circulates about this molecule invoking cell signalling pathways and trial results; we only draw on ANSES, Ciqual or EFSA sources, and none of them validates any effect for this substance. What we can honestly describe is short: a plant-derived molecule, a dose of 510 mg per day, a one-month bottle, and a usage protocol. That is little, and it is everything that can be verified.

What can be credited to this product, on the other hand, is its honesty of formulation: a single active, a clearly displayed dose, no blend concealing the quantities. In an aisle where “proprietary complexes” mainly serve to hide laughable doses, that counts for something, and it at least makes comparison possible.

How do you take Natural Physique?

Dose: 2 capsules a day, i.e. 510 mg. Liquid: a glass of water. Timing: 1 capsule in the morning with breakfast, 1 capsule in the evening with dinner. Frequency: two split servings. Duration: a cycle of 8 to 12 weeks, followed by a 2 to 4 week break.

The manufacturer advises taking the capsules with a meal containing protein. The morning-evening split comes from them too: the aim is to spread the intake out rather than concentrate it.

One point we applaud, because it is rare: the manufacturer writes themselves that ecdysterone is not a miracle solution and that it replaces neither progressive resistance training nor a controlled diet. We would say nothing different. Without a training stimulus, this bottle will be of no use whatsoever.

They also pair their protocol with nutritional recommendations which are, for their part, the serious side of the subject: hydration of 3 to 4 litres per day, a moderate calorie surplus of 300 to 500 kcal and a protein intake of 2 to 2.5 g per kilo of body weight. If you are not holding those three lines, start with them — they will produce more than any capsule, and our mass gain aisle exists for exactly that.

One last practical piece of advice, and it is common sense: measure. Body composition, lifting records, tape measurements, every two to three weeks. On a product with no effect documented by a health authority, that is the only way to know whether you are spending your money usefully.

Who is this product for, and who is it not for?

It is aimed at adults doing resistance training who want to try this molecule with their eyes open, with a legible dose and no blend. The plant-based capsule makes it accessible to vegetarians and vegans.

One piece of information is decisive for some buyers, and the manufacturer states it themselves: ecdysterone has been on the World Anti-Doping Agency's monitoring list since 2020. It is not banned as things stand, but it is being watched. If you hold a competition licence, check your federation's rules before taking it, and bear in mind that monitored status can change.

The manufacturer rules it out for pregnant or breastfeeding women, advises against it for the under-18s, and makes medical advice mandatory in the event of liver or kidney disorders. Anyone on medication should seek advice before use. The product is made in a facility that handles celery, crustaceans, fish, milk, mustard, peanuts, soya, gluten, egg, lupin and molluscs: the list of possible traces is one of the longest in the catalogue.

What you should not expect from it: a shortcut. If your diet, your sleep and your training programme are not already in place, this product will make up for nothing. And if you are looking for a supplement whose effect on performance is recognised by European regulation, this is not the one — read the next section.

Ecdysterone or creatine?

That is the honest comparison, and we make it willingly even though it does not work in favour of the page you are reading.

Creatine monohydrate is the only performance supplement for which a claim is authorised in Europe: “creatine increases physical performance in successive bursts of short-term, high intensity exercise”, from 3 g per day. It also costs a fraction of the price of an ecdysterone, it is taken by the spoonful, and the track record behind it is considerable. If you are not yet taking creatine, that is where to start, without a second's hesitation.

Natural Physique is aimed at people who already have everything dialled in — diet, sleep, training, creatine — and who want to try something else knowing exactly what they are buying: a molecule with no authorised claim, at 510 mg per day, over a two to three month cycle. That is a legitimate choice, provided it is an informed one.

Three other routes are worth more than a capsule if your foundations are not in place: covering your intake with a protein or a whey isolate if you are not hitting your 2 g per kilo, and working on endurance across long sets with the beta-alanine aisle. These are less spectacular levers and considerably more reliable ones.

Frequently asked questions

Is ecdysterone a hormone?

No. It is a phytosteroid, a plant-derived molecule found in particular in spinach and quinoa. The word “steroid” here denotes a chemical family, not an androgenic hormone. The manufacturer also states that this product does not cause hormonal suppression.

Why do you not describe any effect?

Because no health claim is authorised in Europe for ecdysterone, and because we only draw on ANSES, Ciqual or EFSA sources. Writing that it increases muscle mass or strength would be an offence, whatever publications one may read elsewhere.

Is it allowed in competition?

The manufacturer states that ecdysterone has been on the World Anti-Doping Agency's monitoring list since 2020: it is not banned as things stand, but it is being watched. If you hold a licence, check your federation's rules in force before consuming it, as this status may change.

How long does a bottle last?

Thirty days, at two capsules a day for 60 capsules. The manufacturer recommends a cycle of 8 to 12 weeks: so allow two to three bottles for a full cycle, followed by a 2 to 4 week break.

Why split it between morning and evening?

That is the protocol chosen by the manufacturer: one capsule at breakfast, one at dinner, each with a meal containing protein. The stated aim is to spread the intake across the day rather than concentrate it. We report this instruction without attributing any demonstrated effect to it.

Are the capsules suitable for vegans?

Yes. The shell is made of hypromellose, a modified cellulose of plant origin, and no animal ingredient goes into the formula. Do watch out, however, for the long list of possible traces, as the production facility handles milk, egg, fish and crustaceans among others.

Should you take anything alongside it?

If your foundations are not in place, yes, and in order of priority: hit your protein intake, then creatine monohydrate, which is the only performance supplement with an authorised claim. The manufacturer also advises 3 to 4 litres of water a day during the cycle.

Where to buy TrainedByJP Natural Physique?

The 60-capsule bottle can be ordered from this page, and we ship throughout France and Europe. It is a niche product, to be reserved for those whose training and diet are already solid.

At the Vendargues shop, about ten minutes from Montpellier, this is the product page we go through most slowly with a customer, because it requires distinguishing what is written on the label from what regulation allows us to assert. Two very different things, and in this aisle the gap is the widest in the catalogue. The rest of the catalogue can be browsed in our sports nutrition section.
